Crystal report - 2 tables link together. miss some data

Hi,
I have a enrolment table which show what segment and year candidates enrolled.
I need to create a report show a candidate enrol for segment A and/or enrol segment B.

I have insert the same table 2 times and link to each other, left outer join. So it suppose whover sit for segment A will show up no matter they sit segment B or not.

The problems is enrolment table is including all different segments. I need to filter out just show segment B. Once I applied this filter, it would only show candidates sit for A and B. Candidate sit for segment A, not sit segment B is not showing.

Thanks
Meko

If you filter on the right table in a left join, Crystal converts the join to INNER or EQUAL since it can't compare NULL to the value.

Where are you wrinting the SQL?

I haven't written any SQL, just jusing the selection expert.

Ok.  Crystal wrote it and as I stated it turns the join into INNER since it won't compare NULL to a value.

You will have to do this through conditional suppression.

Remove the selection filter.

Suppress the record based on
Not IsNull({TableB.FIeld})

Sorry to ask, how can I do this :


Suppress the record based on
Not IsNull({TableB.FIeld})

Hi

I got the report  like this. What I need to generate is Cand sit segment A and pass segment A and cand without sit Segment at all (so CandID 123) also come up in my record.
CandID and Segment/Result is in 2 different table.
If I select segment ="A" or null, will not have any result come up because Segment not equal to null in its table.


CandID      Segment      Result
123            
234      A      Pass
234      B      Fail
234      C      Fail
