Null handling in Transfomer

Hi All,
I want to give this condition in the Constraint tab of Transformer:
C_ID IS NOT NULL AND A_ID IS NOT NULL
How do I give this in DataStage?
I want the Transformer to pass those records which don't have NULLs in their IDs.
Thanks in advance.

In the transformart constraint add below constraints.
Code: Select all
IsNotNull(C_ID) And IsNotNull(A_ID)

I'm assuming that's new syntax in 8.x or perhaps custom work. For earlier versions the answer would be:
Code: Select all
Not(IsNull(C_ID)) And Not(IsNull(A_ID))

No.It's there in 7.5 versions as well. I am working on 7.5.1

The IsNotNull() just gets compiled to Not(Isnull())

You mean it's a
transform? One I've yet to notice after all this time? Sheesh.
Edit: OK, I feel a little better here - there's no such thing in my 7.5.2 installation. It would be easy enough to whip one up, you sure that's not custom work?
Now, there is such a thing in a
Parallel Transformer, but
not in Server, and since this was marked as a Server question my answer stands.
