Advanced Sql-Shape Query - Help

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 !Hi
I have never used SHAPE/OLEDB, but in T-SQL you can do:
SELECT t1.* FROM tbl1 t1 WHERE EXISTS ( SELECT * FROM tbl2 t2 WHERE t1.field
= t2.field )
Therefore you may want to try this as your parent query.
