let me be clearer. I need to return an estimate of the number of rows for 'pagination'. The user will page through 25 rows a time, but wants an estimate on the total number of rows returned. I want to avoid counts.
tom kytes book says to use v$sql_plan, but how do i get my exact query? Id prefer to do it without table joins. Since I have a very strict SLA. dbms_xplan is returning the whole thing. I just want the cardinality and I have to put it in a variable. ----- Original Message ----- To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: Monday, December 29, 2003 4:59 PM > i need to return the cardinality estimate to the user as a number. how do i do that? > > > > From: Stephane Faroult <[EMAIL PROTECTED]> > > Date: 2003/12/29 Mon PM 04:29:26 EST > > To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> > > Subject: Re: getting estimate of result set from v$sql_plan > > > > [EMAIL PROTECTED] wrote: > > > > > > can someone send me the query I use to hit v$sql_plan to get my estimated cardinality for a query? > > > > > > > > > > @$ORACLE_HOME/rdbms/admin/utlxpls.sql > > or > > $ORACLE_HOME/rdbms/admin/utlxplp.sql if you have parallelism. > > -- > > Regards, > > > > Stephane Faroult > > Oriole Software > > -- > > Please see the official ORACLE-L FAQ: http://www.orafaq.net > > -- > > Author: Stephane Faroult > > INET: [EMAIL PROTECTED] > > > > Fat City Network Services -- 858-538-5051 http://www.fatcity.com > > San Diego, California -- Mailing list and web hosting services > > --------------------------------------------------------------------- > > To REMOVE yourself from this mailing list, send an E-Mail message > > to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in > > the message BODY, include a line containing: UNSUB ORACLE-L > > (or the name of mailing list you want to be removed from).
