Ø Lookup override query
1. in this query, must use “as” to define the column, otherwise, Informatica will treat as invalid query.
2 .Not support columns in nest query for example:
select 'AA'as A,(select 'BB' from dual) as B from dual;
in this case, change query to use sub query
Select C.A AS A, C.B AS B
from (select 'AA' as A, (select 'BB' from dual) as B from dual) C
Ø In the mapping level, expression trans,when use local variable
Can only use variable port directly.can not use nest nest variable. For example,
|
