Hi, could somebody explain me please why following select SELECT docid FROM prod.guids GROUP BY docid HAVING( COUNT(docid) > 1 )
taking 15 min on 2 Proc Box on 1M rows, where number of duplicates around 300K, and docid indexed and not null and char(16). May be I am doing something wrong? Thank you. ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
