Transformer Null handling and reject link

[TITUS_007]

hello,

i have a problem with Transformer, I would like if a column is null that the row is not rejected.

Can you give me a solution, Which stage use before ?

Thanks

Is a warning or other message being logged? Do you have constraints on the output link? What exactly do you mean by "rejected"?

No-one can know the why unless you provide more information on what you are doing or seeing, right now we'd only be guessing.

[ray.wurlod]

The field in question must be marked Nullable on the output link.

No Transformer function can be supplied with NULL as an argument (this requirement is relaxed, we are informed, in the next version of DataStage). Therefore any incoming NULL must be intercepted and not passed to the function.
If IsNull(InLink.TheField) Then SetNull() Else TheFunction(InLink.TheField)

Ray does tend to be a pretty good guesser, though.

[TITUS_007]

the field is marked nullable on the input link and no constraints on output link
and not nullable on output link.

I have a reject link on the transformer.

What is the best stage to transform in a field NULL to # for example ?

Since you already have a transform stage in the job then use that stage and a NullToValue() function.

NulltoValue() is a great function of datastage. I found this only lately.
Otherwise i was quite confused on how to handle null data.
