Conditional Table Joins

Hi all,
I'm having a little trouble with producing a query for MS SQL Server
2000 with a conditional join in.
The basis of the structure is that when an order is active, the
OrderID of any book in the Order is stored in the book record in the
Books table. If an order is cancelled, the OrderID is removed from the
record in the Books table, to enable the book to be put back on sale.
At that point, for each book cancelled, a record is appended to the
CancelledRefundedBooks table, with just the book reference number
(foreign key of the Books table), and the OrderID it belonged to. This
is to us to still see which books were in a cancelled order. I hope
that made sense! i've posted the table defs for these tables at the
bottom of this message.
My problem is when using the following stored procedure query to
search for orders based on different criteria, included a reference
number for a book in the order, the join with the books table is
causing cancelled orders not to be returned. For example, if i search
for active order 1, because one of the possible search criteria is
book reference, the Books table is joined to the query. Because order
1 is active, the book records in the Books table have orderID's
stored, and the order is returned. However, if i search for cancelled
order 2, because the books are lacking the OrderID field, the join is
causing the order record not to be returned. I have tried using an
INNER JOIN and a LEFT OUTER JOIN, and neither help. The ideal
situation would be if the join for the Books table could be
conditional on the OrderStatusID field in the Orders table, so that
the query would be joined to the Books table if the order was active,
and if the order was cancelled, the join would change to the
CancelledRefundedBooks table.
An additional complication is that if the join was to the
CancelledRefundedBooks table, in the event of a cancelled order, the
CancelledRefundedBooks table holds only the book reference numbers.
This means that table would then need a further join onto the Books
table to retrieve author, title etc. fields.
The stored proc as it stands is as follows:
ALTER PROCEDURE sp_searchorders
@.refnumber int = NULL,
@.surname nvarchar(100) = NULL,
@.orderid int = NULL,
@.postcode nvarchar(50) = NULL,
@.booktitle nvarchar(500) = NULL
WITH RECOMPILE
AS
SELECT DISTINCT
Orders.OrderID, Staff.Surname AS StaffSur,
Staff.FirstName AS StaffFir, Orders.CustomerID, Customers.Forenames,
Customers.Surname,
Customers.Telephone, Customers.Email,
Customers.Forenames, Customers.Surname, Customers.TownCity,
Websites.Name AS Website, Orders.OrdDate
FROM Orders INNER JOIN
Customers ON Orders.CustomerID = Customers.CustomerID INNER JOIN
Staff ON Orders.StaffID = Staff.StaffID INNER
JOIN
Websites ON Orders.WebsiteID = Websites.WebsiteID LEFT OUTER JOIN
Books ON Orders.OrderID = Books.OrderID
WHERE CASE @.refnumber
WHEN 0 THEN @.refnumber
ELSE Books.Ref
END
= @.refnumber
AND Customers.Surname LIKE COALESCE(@.surname, '%')
AND Books.Title LIKE COALESCE(@.booktitle, '%')
AND Customers.Postcode LIKE COALESCE(@.postcode, '%')
AND CASE @.orderid
WHEN 0 THEN @.orderid
ELSE Orders.OrderID
END
= @.orderid
My sincerest apologies for posting such a long narrative about the
problem, but I can't think of any other way of describing it! I have
included the CREATE statements for all the mentioned tables below, and
if i can provide any more information to help come up with a solution
plz ask. I am a relative newbie at SQL server, so please be gentle!!
Many thanks in advance

GOJames,
I did not go beyond your second paragraph. I believe your db design is
flawed. If you keep an OrderID in your Book table for an active order, how
do you deal with the situation that there more than one orders that buy the
same book?

Conditional Sum trouble

Can someone help me figure this out? I'm trying to total up 4 columns which
have been X'd to indicate inventory types: RAWX, NSFGX, BUYX and SFGX.
I've tried:
=iif( Fields!RAWX.Value = "X", Sum(Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0)
=iif( Fields!NSFGX.Value = "X", Sum(Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0)
=iif( Fields!BUYX.Value = "X", Sum(Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0)
=iif( Fields!SFGX.Value = "X", Sum(Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0)
The reoport runs without errors, but I get a Grand Total for RAWX and 0 for
the other three columns.
If I change the expressions to:
=Sum(iif( Fields!RAWX.Value = "X", (Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0))
=Sum(iif( Fields!NSFGX.Value = "X", (Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0))
=Sum(iif( Fields!BUYX.Value = "X", (Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0))
=Sum(iif( Fields!SFGX.Value = "X", (Fields!BKIC_PROD_AVGC.Value *
Fields!BKIC_PROD_UOH.Value), 0))
I get #ERROR in all columns and a warning for each field:
"The value expression for the textbox â'RAWXâ' uses an aggregate function on
data of varying data types. Aggregate functions other than First, Last,
Previous, Count, and CountDistinct can only aggregate data of a single data
type.
BKIC_PROD_AVGC and BKIC_PROD_UOH are the same data type.
What is this message trying to tell me?Did you try this for the RAWX column?
=iif( Fields!RAWX.Value = "X", Sum(Fields!BKIC_PROD_AVGC.Value) *
Sum(Fields!BKIC_PROD_UOH.Value), 0)
--
I would also try to display the conditional value for the other three
to verify that those fields equal your "X" value
For example (for the NSFGX column), just put
= (Fields!NSFGX.Value = "X")
and see if it returns 'True' or 'False'
that may lead you in the right direction.
--
Also, I'm not sure how your report is set up, but did you notice that
for each of your columns, you're referencing the same values (
Fields!BKIC_PROD_AVGC.Value and Fields!BKIC_PROD_UOH.Value )?

Conditional stored procedure question

I need to create a stored proc which has a conditional WHERE clause depending on the value of a passed parameter. I'm having trouble handling the condition. I'm missing something here.

CREATE PROCEDURE Milestone_Get
(@.myID int, @.iShowAll int)

AS

SELECT uid, name, date, registration_confirmed
FROM tbl_members

WHERE
If @.iShowAll = 0
begin
(uid = @.myID) AND (registration_complete = 0)
end
else
begin
(uid = @.myID)
end

GO

Thanks,
davidyou can use a CASE statement but i do not know the syntax..heres another way of doing it

CREATE PROCEDURE Milestone_Get
(@.myID int, @.iShowAll int)
AS
if @.iShowAll = 0
 SELECT uid, name, date, registration_confirmed FROM tbl_members where uid = @.myID AND registration_complete = 0
else
 SELECT uid, name, date, registration_confirmed FROM tbl_members where uid = @.myID
go

HTH|||Here's an example using a Case

SELECT uid, name, date, registration_confirmed FROM tbl_members
WHERE (uid = @.myID) AND registration_complete = CASE WHEN @.iShowAll = 0 THEN 0 ELSE registration_complete END

Conditional SELECT

Dear Group

I'm having trouble with the statement below. I tried CASE and IF
without success. What I'm trying to do:
There is a field in the database called Business_TelNo. If the field
has some value, I would like to return a generated field
(LaBusinessTelNo), which is the label of Busines_TelNo, reading
'Phone:'
If Business_TelNo has no value, the label should be set to ''.

Something like this:
SELECT i2b_vw_contact.Business_TelNo AS Business_TelNo,
IF (LEN(Business_TelNo) > 0) BEGIN SELECT 'Phone: ' AS LaBusinessTelNo
END ELSE BEGIN SELECT '' AS LaBusinessTelNo END
FROM i2b_vw_contact

This is working:
SELECT i2b_vw_contact.Business_TelNo AS Business_TelNo,
'Phone: ' AS LaBusinessTelNo
FROM i2b_vw_contact

PS: I know it would be much easier to add some logic in the
application but need to do this in SQL.

Thanks very much for your time and efforts!

MartinSELECT business_telno,
CASE WHEN business_telno>'' THEN 'Phone: ' ELSE '' END AS labusiness_telno
FROM i2b_vw_contact

You can find the CASE and IF syntax in Books Online but understand that CASE
is an *expression* whereas IF is a *statement* and therefore IF can't be
used as part of a query.

Conditional page breaks in SSRS

Hi,

I am having trouble setting conditional page breaks to my reports.

i.e... I am having a report where I need to allow user the option to set page break between a group or not.

Based upon the option selected by the user, I need to add page break to the report. I tried with all possibilities inside Sort and Group dialog box, but could not figure out how to toggle the option at runtime.

Does anyone know how to implement page breaks on runtime? Help me plzzzz!! I really need this to be done…Thanx in advance for any help..

- Rayz

OK, I think I have succeeded in doing this...

create a boolean parameter, something like PageBreak --
I would give it a default value, but it doesn't appear to be necessary if you don't want it.
create a group with "page break at end", as you normally would. Don't put anything in its header and footer lines.
here's the trick: make this group's grouip expression an IIF() containing your "real" group expression,
something like the following example:|||

I tried it out ..but no luck for me

Wherever i apply page break..it seems it wont take the condition that i've specified..and pagebreaks appears permanently..even if i dont put pagebreak no..the page break comes..

Thanks for your suggestion

-Rayz

|||

Well, let's see...

>>it seems it wont take the condition that i've specified..and pagebreaks appears permanently

What is the condition you've specified?

Also, to make sure I can repro, is this an RDL or RDLC?

>L<

|||Perhaps you should extend the syntax that Lisa has shown with the IIF() function. If you set the group expression as previously mentioned and add a field reference that is global to the report instead of the empty field ( "" ) then perhaps this evaluate correctly.

=IIF(Parameters!PageBreak.Value, Fields!MyField.Value, Fields!MyMostGlobalField.Value)

This way you will get a field reference to evaluate the grouping to. You may additionally want to hide this group with a "Visibility" expression on the group, though you may still get a page break before your report footer if one exists.

Hope this helps.

Hi Paul,

It actually does work fine with the "" -- and in the past I've done this with other "global/invariant" expressions -- such as True or 1. Is there some reason why this is a bad idea?

BTW another way I do this, without an IIF(), is to group on a variable and increment the variable in code when I want to force a page break -- I haven't tried that in RS and it can be a little more difficult to manage in general. So I didn't try it in response to this query. I will try it if you think it's a better idea.

Regrads,

Hi,

I have five tables in a report which has to be repeated on every sheet of excel based on a variable

Can i also use the same condition?

Kindly help me out.

Thanks in advance

"Every sheet of Excel" is basically "every explicitly-requested page of the report". By that I mean you get a sheet for each page break you explicitly asked for with a page break condition, rather than the report just deciding that it has to page break based on some constraints of the host format (for example, physical page size).

So, "Excel" shouldn't be handled specifically when trying to repeat tables -- it should work the way you want, if you get the explicit page break requests correct.

I will assume you understand this (I almost wrote "that we're on the same page" <g>) and ignore the "Excel" part of the question...

So, you want to have five tables that you want to see on each page. Can you tell me some more about your layout, what each of the tables represent from the point of view of datasets? Are they related to each other or completely distinct, data-wise? Is there additional data in the report? are the tables positioned adjacent to each other vertically, or horizontally, or what?

Lisa, I tried your approach and found two problems that I still can't figure out.

1) I had to do the Page break before the sections rather than after section in order for it to work.

2) I need to be able to choose the group level to page break on OR choose that no page break occurs at all. In this pursuit, I can't find a solution. Even if the Parameter!PageBreak criteria is not met, the top level group always page breaks. I need the ability to eliminate the page break as one of my options.

Any ideas?

|||

Well, it definitely does work and should not require page break before -- in fact using page break before might be why you're saying "top level always breaks".

I am not on a machine where I have any of these examples, and, clearly, we need to take this from the top.

Can I have a clear(er) statement of exactly what you've done so far in this report and also a separate statement of what the requirements are? This would optimally include some simplified SELECT or other way that I can repro exactly what your group breaks look like, there may be some collision that we have to account for that wasn't in the original suggestion (or maybe the collision *can't* be accounted for in your situation -- right now I honestly have no idea).

I'm leaving for the day now, so no rush on your response <s>

I just created a stripped down sample report, and the issue with using page break after went away, but the other issue remains. I have a parameter named PageBreak with three option values: NONE, GROUP1, and GROUP2. When i choose NONE, it should always evaluate the Group1pre and Group2pre as ="" and therefore never cause a page break during the report. Unfortunately, it still causes the GROUP1 page breaks even if I choose NONE.

I created four group levels sequenced as follows (as seen in the Groups tab of Table Properties) and a detail row with the Detail values:

table1_Group1pre, page break at end checked, group expression =IIF(Parameters!PageBreak.Value="GROUP1",Fields!Group1.Value,"")

table1_Group1, no page breaks, group expression =Fields!Group1.Value

table1_Group2pre, page break at end checked, group expression =IIF(Parameters!PageBreak.Value="GROUP2",Fields!Group2.Value,"")

table1_Group2, no page breaks, group expression =Fields!Group2.Value

Here is the data set I created for testing.

select 'ABC' as Group1, '123' as Group2, 'slfje' as Data
union all
select 'ABC' as Group1, '123' as Group2, 'redfg' as Data

Thank you for taking such care to provide a reproducible sample. I will check this out and write back, whether I can do this or not, and I have no idea at the moment <s>. I do know that it's a chancey thing, and it's often tricky to get the conditional expressions right, so I usually take a while to get it to work.

Anyway, I'll give this a shot and report back...

>L<

OK -- you can do this, it will work <s>. What you're missing (I think) is that you have to put the conditionals on the outer rim of the "real" groups. IOW, your group order is this:

Group1pre

Group1

Group2pre

Group2

... and it is quite possible that it would have worked something like this:

Group1pre

Group2pre

Group1

Group2

... although I didn't try it that way.

What I did try successfully, and what appears to follow the "rules of engagement" as I understand them (my understanding being without inside knowledge, just observation, and is admittedly imperfect!), is this:

GroupsPre

Group1

Group2

... using the following expression as my conditional break on GroupsPre:

Code Snippet

=IIF(Parameters!PageBreak.Value="NONE","",

IIF(Parameters!PageBreak.Value="GROUP1",
Fields!Group1.Value,

Fields!Group2.Value)
)

I want to say one other thing, based on your sample data -- which may be compounded in something you're doing in your "real" data set:

I am not sure what effect you are after on the inner group break, but you may have to dynamically sort your data to get the effect you are after when the break is on "GROUP2" (your inner group as expressed in the report). It is certainly possible to do this, of course, and I'm not even sure that is an issue for you.

Conditional page breaks in SSRS

Hi,

I am having trouble setting conditional page breaks to my reports.

i.e... I am having a report where I need to allow user the option to set page break between a group or not.

Based upon the option selected by the user, I need to add page break to the report. I tried with all possibilities inside Sort and Group dialog box, but could not figure out how to toggle the option at runtime.

Does anyone know how to implement page breaks on runtime? Help me plzzzz!! I really need this to be done…Thanx in advance for any help..

- Rayz

OK, I think I have succeeded in doing this...

create a boolean parameter, something like PageBreak --
I would give it a default value, but it doesn't appear to be necessary if you don't want it.
create a group with "page break at end", as you normally would. Don't put anything in its header and footer lines.
here's the trick: make this group's grouip expression an IIF() containing your "real" group expression,
something like the following example:|||

I tried it out ..but no luck for me

Wherever i apply page break..it seems it wont take the condition that i've specified..and pagebreaks appears permanently..even if i dont put pagebreak no..the page break comes..

Thanks for your suggestion

-Rayz

|||

Well, let's see...

>>it seems it wont take the condition that i've specified..and pagebreaks appears permanently

What is the condition you've specified?

Also, to make sure I can repro, is this an RDL or RDLC?

>L<

|||Perhaps you should extend the syntax that Lisa has shown with the IIF() function. If you set the group expression as previously mentioned and add a field reference that is global to the report instead of the empty field ( "" ) then perhaps this evaluate correctly.

=IIF(Parameters!PageBreak.Value, Fields!MyField.Value, Fields!MyMostGlobalField.Value)

This way you will get a field reference to evaluate the grouping to. You may additionally want to hide this group with a "Visibility" expression on the group, though you may still get a page break before your report footer if one exists.

Hope this helps.

Hi Paul,

It actually does work fine with the "" -- and in the past I've done this with other "global/invariant" expressions -- such as True or 1. Is there some reason why this is a bad idea?

BTW another way I do this, without an IIF(), is to group on a variable and increment the variable in code when I want to force a page break -- I haven't tried that in RS and it can be a little more difficult to manage in general. So I didn't try it in response to this query. I will try it if you think it's a better idea.

Regrads,

Hi,

I have five tables in a report which has to be repeated on every sheet of excel based on a variable

Can i also use the same condition?

Kindly help me out.

Thanks in advance

Nalini

"Every sheet of Excel" is basically "every explicitly-requested page of the report". By that I mean you get a sheet for each page break you explicitly asked for with a page break condition, rather than the report just deciding that it has to page break based on some constraints of the host format (for example, physical page size).

So, "Excel" shouldn't be handled specifically when trying to repeat tables -- it should work the way you want, if you get the explicit page break requests correct.

I will assume you understand this (I almost wrote "that we're on the same page" <g>) and ignore the "Excel" part of the question...

So, you want to have five tables that you want to see on each page. Can you tell me some more about your layout, what each of the tables represent from the point of view of datasets? Are they related to each other or completely distinct, data-wise? Is there additional data in the report? are the tables positioned adjacent to each other vertically, or horizontally, or what?

>L<

|||

Lisa, I tried your approach and found two problems that I still can't figure out.

1) I had to do the Page break before the sections rather than after section in order for it to work.

2) I need to be able to choose the group level to page break on OR choose that no page break occurs at all. In this pursuit, I can't find a solution. Even if the Parameter!PageBreak criteria is not met, the top level group always page breaks. I need the ability to eliminate the page break as one of my options.

Any ideas?

|||

Well, it definitely does work and should not require page break before -- in fact using page break before might be why you're saying "top level always breaks".

I am not on a machine where I have any of these examples, and, clearly, we need to take this from the top.

Can I have a clear(er) statement of exactly what you've done so far in this report and also a separate statement of what the requirements are? This would optimally include some simplified SELECT or other way that I can repro exactly what your group breaks look like, there may be some collision that we have to account for that wasn't in the original suggestion (or maybe the collision *can't* be accounted for in your situation -- right now I honestly have no idea).

I'm leaving for the day now, so no rush on your response <s>

I just created a stripped down sample report, and the issue with using page break after went away, but the other issue remains. I have a parameter named PageBreak with three option values: NONE, GROUP1, and GROUP2. When i choose NONE, it should always evaluate the Group1pre and Group2pre as ="" and therefore never cause a page break during the report. Unfortunately, it still causes the GROUP1 page breaks even if I choose NONE.

I created four group levels sequenced as follows (as seen in the Groups tab of Table Properties) and a detail row with the Detail values:

table1_Group1pre, page break at end checked, group expression =IIF(Parameters!PageBreak.Value="GROUP1",Fields!Group1.Value,"")

table1_Group1, no page breaks, group expression =Fields!Group1.Value

table1_Group2pre, page break at end checked, group expression =IIF(Parameters!PageBreak.Value="GROUP2",Fields!Group2.Value,"")

table1_Group2, no page breaks, group expression =Fields!Group2.Value

Here is the data set I created for testing.

Thank you for taking such care to provide a reproducible sample. I will check this out and write back, whether I can do this or not, and I have no idea at the moment <s>. I do know that it's a chancey thing, and it's often tricky to get the conditional expressions right, so I usually take a while to get it to work.

Anyway, I'll give this a shot and report back...

>L<

OK -- you can do this, it will work <s>. What you're missing (I think) is that you have to put the conditionals on the outer rim of the "real" groups. IOW, your group order is this:

Group1pre

Group1

Group2pre

Group2

... and it is quite possible that it would have worked something like this:

Group1pre

Group2pre

Group1

Group2

... although I didn't try it that way.

What I did try successfully, and what appears to follow the "rules of engagement" as I understand them (my understanding being without inside knowledge, just observation, and is admittedly imperfect!), is this:

GroupsPre

Group1

Group2

... using the following expression as my conditional break on GroupsPre:

Code Snippet

=IIF(Parameters!PageBreak.Value="NONE","",

IIF(Parameters!PageBreak.Value="GROUP1",
Fields!Group1.Value,

Fields!Group2.Value)
)

I want to say one other thing, based on your sample data -- which may be compounded in something you're doing in your "real" data set:

I am not sure what effect you are after on the inner group break, but you may have to dynamically sort your data to get the effect you are after when the break is on "GROUP2" (your inner group as expressed in the report). It is certainly possible to do this, of course, and I'm not even sure that is an issue for you.

[LSN Editing next morning: instead of dynamic orderng you can probably concatenate the value in the last part of the expression as csi_hugh shows in the next post]

Conditional page breaks in SSRS

Hi,

I am having trouble setting conditional page breaks to my reports.

i.e... I am having a report where I need to allow user the option to set page break between a group or not.

Based upon the option selected by the user, I need to add page break to the report. I tried with all possibilities inside Sort and Group dialog box, but could not figure out how to toggle the option at runtime.

Does anyone know how to implement page breaks on runtime? Help me plzzzz!! I really need this to be done…Thanx in advance for any help..

- Rayz

OK, I think I have succeeded in doing this...

create a boolean parameter, something like PageBreak --
I would give it a default value, but it doesn't appear to be necessary if you don't want it.
create a group with "page break at end", as you normally would. Don't put anything in its header and footer lines.
here's the trick: make this group's grouip expression an IIF() containing your "real" group expression,
something like the following example:|||

I tried it out ..but no luck for me

Wherever i apply page break..it seems it wont take the condition that i've specified..and pagebreaks appears permanently..even if i dont put pagebreak no..the page break comes..

Thanks for your suggestion

-Rayz

|||

Well, let's see...

>>it seems it wont take the condition that i've specified..and pagebreaks appears permanently

What is the condition you've specified?

Also, to make sure I can repro, is this an RDL or RDLC?

>L<

|||Perhaps you should extend the syntax that Lisa has shown with the IIF() function. If you set the group expression as previously mentioned and add a field reference that is global to the report instead of the empty field ( "" ) then perhaps this evaluate correctly.

=IIF(Parameters!PageBreak.Value, Fields!MyField.Value, Fields!MyMostGlobalField.Value)

This way you will get a field reference to evaluate the grouping to. You may additionally want to hide this group with a "Visibility" expression on the group, though you may still get a page break before your report footer if one exists.

Hope this helps.

Hi Paul,

It actually does work fine with the "" -- and in the past I've done this with other "global/invariant" expressions -- such as True or 1. Is there some reason why this is a bad idea?

BTW another way I do this, without an IIF(), is to group on a variable and increment the variable in code when I want to force a page break -- I haven't tried that in RS and it can be a little more difficult to manage in general. So I didn't try it in response to this query. I will try it if you think it's a better idea.

Regrads,

Thanx a bunch Lisa....

ur initial suggestion worked !!

Hi,

I have five tables in a report which has to be repeated on every sheet of excel based on a variable

Can i also use the same condition?

Kindly help me out.

Thanks in advance

Nalini

"Every sheet of Excel" is basically "every explicitly-requested page of the report". By that I mean you get a sheet for each page break you explicitly asked for with a page break condition, rather than the report just deciding that it has to page break based on some constraints of the host format (for example, physical page size).

So, "Excel" shouldn't be handled specifically when trying to repeat tables -- it should work the way you want, if you get the explicit page break requests correct.

I will assume you understand this (I almost wrote "that we're on the same page" <g>) and ignore the "Excel" part of the question...

So, you want to have five tables that you want to see on each page. Can you tell me some more about your layout, what each of the tables represent from the point of view of datasets? Are they related to each other or completely distinct, data-wise? Is there additional data in the report? are the tables positioned adjacent to each other vertically, or horizontally, or what?

>L<

|||

Lisa, I tried your approach and found two problems that I still can't figure out.

1) I had to do the Page break before the sections rather than after section in order for it to work.

2) I need to be able to choose the group level to page break on OR choose that no page break occurs at all. In this pursuit, I can't find a solution. Even if the Parameter!PageBreak criteria is not met, the top level group always page breaks. I need the ability to eliminate the page break as one of my options.

Any ideas?

|||

Well, it definitely does work and should not require page break before -- in fact using page break before might be why you're saying "top level always breaks".

I am not on a machine where I have any of these examples, and, clearly, we need to take this from the top.

Can I have a clear(er) statement of exactly what you've done so far in this report and also a separate statement of what the requirements are? This would optimally include some simplified SELECT or other way that I can repro exactly what your group breaks look like, there may be some collision that we have to account for that wasn't in the original suggestion (or maybe the collision *can't* be accounted for in your situation -- right now I honestly have no idea).

I'm leaving for the day now, so no rush on your response <s>

I just created a stripped down sample report, and the issue with using page break after went away, but the other issue remains. I have a parameter named PageBreak with three option values: NONE, GROUP1, and GROUP2. When i choose NONE, it should always evaluate the Group1pre and Group2pre as ="" and therefore never cause a page break during the report. Unfortunately, it still causes the GROUP1 page breaks even if I choose NONE.

I created four group levels sequenced as follows (as seen in the Groups tab of Table Properties) and a detail row with the Detail values:

table1_Group1pre, page break at end checked, group expression =IIF(Parameters!PageBreak.Value="GROUP1",Fields!Group1.Value,"")

table1_Group1, no page breaks, group expression =Fields!Group1.Value

table1_Group2pre, page break at end checked, group expression =IIF(Parameters!PageBreak.Value="GROUP2",Fields!Group2.Value,"")

table1_Group2, no page breaks, group expression =Fields!Group2.Value

Here is the data set I created for testing.

select 'ABC' as Group1, '123' as Group2, 'slfje' as Data

Conditional format within matrix, depending on subtotal?

Hi there,

I'm having trouble inserting a conditional format to a specific column.

e.g.: Matrix within the rows the "weeks" (1, 2, 3, ... , 52), and in the column a "lastyear revenu", "thisyear revenue" and a difference between them, "delta %", in percent grouped by the stores.
I added a subtotal to it so I get in the latest column the "total lastyear revenue", the "total thisyear revenue" and a difference between them in percent for all stores, "total delta %", for a specific week.

Problem: I want to colour the "delta %" column green when it is greater then the "total delta %" value.

I thougt this would be quite easy, but it really is a pain in the *** because, in the background expression dialog box, I can't refer to the subtotal cells ...

I tried to create a simple report from a cube with Month,Store,Turnover, Previous Year turnover and Delta %. Then I placed on the rows the months and the stores and the values in the colums (that should be the way that you did on the report, am I correct?) and I added the subtotal. Then in the background expression I wrote this:

"=iif(sum(Delta.values) > sum(Delta.values,"Dataset1"),"Green","White")"

Doing this I had the monthly delta background in green when it was higher than the total one.

I hope that I was clear enough!

|||So, am I getting this right:

You simply created another dataset in which you calculate the "total delta %". You then refer in the background expression dialog box to the "total delta %" field of the new dataset?
|||

The dataset is the same, I just refer to the whole dataset in the formula.

So, I have only one dataset (dataset1) and in the % delta for the background I use a formula like:

iif((sum(Fields!CYRevenue.value)-sum(Fields!PYRevenue.value))/sum(fields!PYRevenue.value) > (sum(Fields!CYRevenue.value,"Dataset1")-sum(Fields!PYRevenue.value,"Dataset1"))/sum(fields!PYRevenue.value,"Dataset1"),"Green","White")

Hope it helps!

Conditional Column Formatting

Hi Everyone,
I am trying to hide a column in a matrix table. I have no
trouble using conditional formatting to control the visibility of the
column, but when I hide the column the main row in the matrix does not
shrink. Therefore, I have a big gap... My thought was to use conditional
formatting to control the column width of the main matrix row. Listed
below is the expression that I used. Can anyone help me with the error
message or recommend a better solution?
=IIF(Fields!FiscalYear.Value = IIF(Month(TODAY()) = 10-12,Year(TODAY()) ,Year(Today())-1), 0.625in, 0.25in) cannot be
parsed as a unit because it does not contain numeric values. Examples
of valid unit strings are "1pt" and ".5in".

Did you ever figure this out? I need to control the width of a column but
it appears column width isn't formattable via an expression.

Concurrent SQL Tranasactions Fail

Hi all,
I am having trouble trying to get an efficient way of checking if a
value pair exists in a table, and if not inserting the value pair and
returning the new id in the identity column. The old method I have used
has been fine for some time but the table has grown to a very large
size and the current code is causing a bottleneck.
The table consists the three columns, An identity column and two
nvarchar(15) columns. Instead of replicating the nvarchar(15) columns
over the database I have placed them in a lookup table and use the ID
from the identity column to reference the nvarchar values. I do store
multiple languages in the database so an nvarchar is necessary.
I admit the current code I use below is poor, but all of the
enhancements I have tried to make have resulted in the system failing,
as multiple copies of the procedure run and two (or more) procedures
try and insert the same data into the table (there is a unique
clustered index on the two varchar columns, and the identity column is
the primary key).
As our server application is multithreaded, it is highly likely
(certain) that two or more of these procedures will be running at once
so I have to ensure data integrity whilst checking and updating. Im
just not sure that a TABLOCKX,HOLDLOCK lock hint is the best way.
CREATE PROCEDURE dbo.CreateNewContextItem
@.CONTEXT NVARCHAR(15),
@.DATAITEM NVARCHAR(15),
@.ID INTEGER OUTPUT
AS
SET NOCOUNT ON
BEGIN TRANSACTION
SET @.ID = (SELECT id FROM contextitem WITH (TABLOCKX,HOLDLOCK) WHERE
context = @.CONTEXT AND dataitem=@.DATAITEM)
IF @.ID IS NULL
BEGIN
INSERT INTO
contextitem (context,dataitem)
VALUES
(@.CONTEXT,@.DATAITEM)
IF @.@.ERROR<>0
GOTO Errhandler
SET @.ID = Scope_Identity()
IF @.@.ERROR<>0
GOTO Errhandler
END
COMMIT TRANSACTION
RETURN 0
Errhandler:
ROLLBACK TRANSACTION
RETURN 50063 -- application specific error code
GO
Is there a way of speeding up this procedure whilst still allowing
multiple copies of it to be run at once safely? Any help would be
greatly appreciated.
Thanks in advance.How about UPDLOCK instead of the TABLOCKX hint?
