Hi all,
I am trying to run a query with sub-queries in Oracle 10G Release 2 and it is
taking ages, I divided the query into parts and I have no problems running the
first and third subqueries (together and each one separated) but when I try to
run the second subquery along with the other two or just itself, it takes ages
(I generated a trace and returned a wait of 22 minutes executing the query
giving no results at all).
The table has 22567 records in it and runs PERFECTLY in Oracle 9i, we didn't
change anything while migrating to 10G. It seems there is a problem with the
date being invoked in the second subquery. Do you have any clue about what can
be happening with this query?. Thanks
