conditions, expressions

I have a table

CREATE TABLE [dbo].[CmnLanguage]
(
[Id] [char](2) NOT NULL CONSTRAINT PkCmnLanguage_Id PRIMARY KEY,
[EnglishName] [varchar](26) NOT NULL,
[NativeName] [nvarchar](26) NOT NULL,
[DirectionType] [smallint] NOT NULL,
[IsVisible] [bit] NOT NULL,
[CreatedDateTime] [datetime] NOT NULL DEFAULT GETDATE(),
[ModifiedDateTime] [datetime] NULL
)

We will use these 3 queries

select * from CmnLanguage where IsVisible = 0
select * from CmnLanguage where IsVisible = 1
select * from CmnLanguage

I want to make a method which handles these queries.

But at the back end on Stored Procedures

We have to write 3 queries

Which I don't want to do.

I want to minimize the queries and conditions

and want to just write one for these 3

Can any one do it?

How about this:

SET ANSI_NULLSONGOSET QUOTED_IDENTIFIERONGOCREATE PROCEDURE dbo.sp_MyProcedure(@.IsVisibleAS BIT =NULL)ASBEGINSELECT*FROM[dbo].[CmnLanguage]WHERE[IsVisible] =CASEWHEN @.IsVisibleISNULLTHEN [IsVisible]ELSE @.IsVisibleENDENDGO

Nice.

Very Useful.

Thanks.

Conditional expressions for background color

I am trying to use conditional expressions within a report field to change
the background color depending on the value of one of the fields in the
report.
Within the properties for one of the report items, I click the background
color item and then choose the expressions and that brings up an edit
expression window. I key the following code into the expression pane.
=iff(fields!libseq.value > 2, "Red", "Blue")
when I rebuild the solution or try to run the report, I get the following
message.
C:\VS Test Applications\Report Testing\Report4.rdl The background color
expression for the textbox 'textbox10' contains an error: [BC30451] Name
'iff' is not declared.
Does anyone know what needs to be declared and where?
thanks,
hughIt shoud be IIf and not iff

Thank you for your post.
As Jasper mentioned, the function you use should be Iif not Iff.
Iif is a Visual Basic Fuction. Here is an article for your reference.

Conditional expressions - isnull(A) OR isnull(B)

I am trying to reproduce an expression in my access front-end database
in an SQL view (using Visual Studio 2005 view definition). The
expression is:
SELECT dbo_T200PEOPLE.PersonNo, dbo_T200PEOPLE.FirstName,
dbo_T200PEOPLE.LastName, IIf(IsNull([Password]) Or
IsNull([PasswordHint]),"No","Yes") AS Secured, dbo_T200PEOPLE.Password,
dbo_T200PEOPLE.PasswordHint
FROM dbo_T200PEOPLE;
Can anyone tell me how to reproduce the "IIf(IsNull([Password]) Or
IsNull([PasswordHint]),"No","Yes") AS Secured" part? All help
gratefully received!Take a look at CASE expression in the BOL

this:
CASE
WHEN PEP.Password IS NULL OR
PEP.PasswordHint IS NULL OR
PEP.Salutation IS NULL OR
PEP.FirstName IS NULL OR
PEP.JobTitle IS NULL
THEN 'No'
ELSE 'Yes'
