[AccessD] Query Run time in different databases

Do both dbs have the same tables with the same indexes on them?  If the
second db is missing an index that the query uses, then it may be forced
to do a table scan which is much slower for large tables.  If that is
not the problem, then you will have to give us more information about
these two dbs.

Subject: [AccessD] Query Run time in different databases



I have a query that takes about 10 seconds to run in one database. I
copied the query into another database using the menu bar. The query
tries to run for hours in the database it was copied into. The original
database is larger if that matters. A compact and repair seemed to have
no effect. Any thoughts as to what is happening?

No trees were killed in the sending of this message. However a large
number of electrons were terribly inconvenienced.
