Hi, please help me to get below logic in Derived transformation, SSIS.
Logic:ensure the Docket number is 5 digits and populate with leading zeros if not.
I have to check input number field is 5 digits, if not I have to populate with leading zeros to make it as 5 digits.
It will be more helpful if any one got me the logic.

The easiest thing to do in a case like this is code that looks like the following:

SELECT RIGHT('00000' + DocketNumber,5)

So, you are putting together 5 0s and your docket number and taking the 5 rightmost characters. You have to make sure that your docket number is a character type or else you'll get an error with putting a string together with a numeric type. Also, if your docket number is ever more than 5 characters, you are only going to get the last 5 characters of the docket number.

I'm not sure what the equivalent expression is in SSIS, but that's the same logic should be able to be used anywhere.

If DocketNumber is a numeric datatype, you can cheat like hell.

SELECT RIGHT(DocketNumber+1000000,5)

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
