thanks, so please tell me what do these parameter do ? please give me some scenario about that.

this is the abstract for v8 guide:

" If you use input columns in an output column expression, be aware that a null value in that input column will cause the row to be dropped or, if a
reject link has been defined, rejected. "

my question point to that.

thanks very much!

thanks , got it

thanks , got it

thanks , got it

thanks friends, but this otherwise link is not a reject link. and following is as abstract for v8 developer guide, hopeful you can make it clear: A constraint otherwise link can be defined by: v Clicking on the Otherwise/Log field so a tick appears and leaving the Constraint fields blank. This will ...

Hi chulett, that is true, please read following words from v8: ( this is definitly not "Otherwise/Log field" ) A constraint otherwise link can be defined by: Set the constraint to OTHERWISE. This will be set whenever a row is rejected on a link because the row fails to match a constraint. ...

thanks, but if I don't set this constraint for otherwise link, I think it also catch all the rows when there is not other constraint fired. is that right ? if that is it, why should we need use this setting?

Hello Gurus,

How can I create surrogate key using @INROWNUM/@OUTROWNUM/@NUMPARTITIONS/@PARTITIONNUM, which will minimum the number space ? such as " 1, 2,3 " is better, however " 1, 18, 39" is bad.

thanks very much!

thanks, but does stage variable/constraint/output derivation are evaluated row by row ?

Hello Gurus,

I can set constraint to " OTHERWISE" for a otherwise link in transformer stage . what does that constraint mean?

thanks very much!

Hello Gurus, in transformer stage, if a input columne is null, and this is direct mapping, so corresponding output should be null. but if this null input columne appears in the output derivation, corresponding output will be rejected. how to make this null input column output with derivation if I wa...
