Advanced Sql-Shape Query - Help

[doar123]

Hi,

This is my basic sql shape query:
------------------------------------------------------------
SHAPE {select * from tbl1}
APPEND({SELECT * FROM tbl2 where field1=1} AS RS2 RELATE field TO
field)
------------------------------------------------------------

With this query i get a RecordSet (RS1), who handle all the records
from table tbl1, and a secondary RecordSet (RS2) who handle all the
records from table tbl2, who applies to the criteria that field1=1.

It is possible that RS2 will be empty (zero records) since there is no
record in tbl2 who applies to that criteria.

My wish is to design a query, that will collect only the records from
tbl1, that will have records from tbl2 who applies to the criteria -
that RS2 won't be empty !

I want to influence on the main part of the query (RS1), through the
criteria that is being used in the secondery query (RS2).

I hope that my question is clear enough. thanks !

If I get this right you want this in the SHAPE part:

SELECT * FROM tbl1
WHERE EXISTS (SELECT * FROM tbl2 WHERE tbl2.field = tbl1.fiedl)
