Conditional split questions

I have a zipcode column that contains xxxxx-xxxx, i want to use conditional split so that i can take the last 4 digits and put them into a different column, I tried to use the SUBSTRING ("ZIP", 6, 4) but it returns an error, any ideas on how i can split it?

Thanks.

Actually, I think you want the derived column transform, not the conditional split. Your SUBSTRING should work fine.|||

I think you want a Derived Column Transfomation too, but you have a couple of mistakes, assuming this is a SSIS expression-

You need to remember the SSIS expression syntax is C style and therefore zero based, so index 7 is the start of the last section, I assume you are skipping the hyphen.

You have used double quotes, this makes it a literal.

Try SUBSTRING(Zip, 7, 4)

Both points don't count if you are still trying to do this on SQL, but I assume you wanted a SSIS solution.

As a rule it helps a lot if you give the details of the error, things like error message, as save a lot of guess work when trying to help you.

Conditional Split Question

Hello,

I am have an ID column that sometimes contains all numeric characters and sometimes contains all digits. I would like to the records with all digits (0-9) to continue downstream in my Data Flow. I would like the records that contain characters other than digits to be logged to a table.

This sounds like a job for the Conditional Split transformation, but I don't see a way to easily test for a numeric value. For example, I would like to use something like ISNUMERIC([MyIDField]) for testing the values in my Conditional Split, but I don't see a way to do this.

Do I have to create a Derived Column transformation prior to my conditional split that populates a "numeric" ID column for each of my records then test this Derived Column in my Conditional Split? Seems like more work than I would to see for something as simple as testing for a numeric...

TIA...

"numeric characters and sometimes contains all digits"... digits are numeric? Anyway I'd use my Regular Expression Transform http://www.sqlis.com/default.aspx?91. It will handle the test and split, and regular expressions are great for validating things like this.

Brian,

You are correct, there is no ISNUMERIC() function in the expression evaluator. However, in your case, there is a fairly decent workaround I think.

If you are SURE that the string is never a mix of numeric and character data, you could use the following expression to direct alpha strings (where Col is the name of your input column:

FINDSTRING("0123456789", SUBSTRING(Col, 1, 1), 1) == 0

This expresssion will be true if the first character of Col is an alpha character.

Hope this helps.
