Hi,
I am trying to do a mapping where in I am in need of a UDF to get this working.
I have three values a and b. if a = yyy and b = zzz
If b is present then in output I need yyyzzz - - - constant ( three dash and a constant )
if b is not present then it must be yyyzzzconstant no - - is needed. ( no dash in this case )
I have done this using standard function. I want to check using UDF for my understanding.
