Just guessing, but it seems as if the longer initial run is because the
data is being pulled into the buffers. After that the query is being
answered without disk i/o. See if you can cache the table and if that gets
rid of the initial long run.

Please respond
to ORACLE-L
It's Friday, and I'm having a brain storm. Just to check:
The developers are using ADO to connect to a VB application and want to
pull back a record set. Using ADO means they can't use bind variables.
Returning more than 1 record means they can't use a function (which
WOULD use bind variables). Am I correct in saying that other than tuning
the SQL (done that, it isn't a complex query) or playing around with
Oracle session parameters, there isn't anything else I can do?
(The query takes 1 second the first time it is run, but 10 ms after. It
is used all the time in the callcentre to search postcodes.)
TIA
Craig Healey
