Check the high water mark of this table. May be there are lot of empty blocks due to which count(*) is taking time. -----Original Message----- From: Jordi Adame V [mailto:jordi@xxxxxxxxxxxx] Sent: Thursday, January 29, 2004 6:55 PM To: Oracle-L@xxxxxxxxxxxxx Subject: Dead slow count(*) Hi! I have this table with ~4,000,000 entries When i do a SELECT COUNT(*) FROM TABLE_NAME it takes 4 hours to give me the result, this is way too much Im running Oracle 9.2.0.4.0 on RedHat AS 3 These are my first experiences with Oracle, so I have no clue how to fix this query time... Any help would be nice regards Jordi ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at http://www.freelists.org/archives/oracle-l/ FAQ is at http://www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at http://www.freelists.org/archives/oracle-l/ FAQ is at http://www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
