Hi All,

Is it possible to use Semi Joins in an Obiee Answer Report?

What i want in pseudo code is: Select <something> From <Starmodel> Where Not Exist <Correlated Subquery>

I know it is possible to do direct SQL but that is not what i'm looking for.

TIA

    Depending on what you actually mean with this you may want to look at the filter option: Filter based on another analysis

    Thanks Christian,

    I have looked into that but I think that way you will be able to do NOT IN subqueries but I don't see how to do NOT EXIST from there.

    I suppose I should have searched the forum first because this has already been answerred: .

    This describes to rewrite the query using a outer join.

    Still, I think a NOT EXIST makes more sence semantically so I would prefer to use that approach if possible.
