Try to find the appropriate access plan(s) in the SQE plan cache and delete

If no access plan exists any more it is built by scratch.

Subject: Force rebuild of SQL Access Plan?

Hi all,

I?m having trouble with a dynamic query on our production server being run
in one of our SQLRPGLE programs. All indices used by the query exists on
both our development system and production system. The data contents of the
tables are essentially the same but the access path on the production system
is using a table scan instead of an index probe.

We changed the query to do a ?in(subselect union subselect)? instead of a
?in (subselect) or in(subselect)? and this allowed the query to run with the
correct index. But we don?t want to change the embedded SQL in the program,
just force the DBMS to rebuild the access path of the ?in (subselect) or
in(subselect)? query.

Is this possible? If so how?

Thanks and Regards,
Mathias
