Hi Larry, I think that the answer is that the statistics are of no use to the CBO until an index is created. @ Regards, @ Steve Adams @ http://www.ixora.com.au/ @ http://www.christianity.net.au/ -----Original Message----- Sent: Friday, 2 February 2001 11:16 To: Multiple recipients of list ORACLE-L non-indexed columns Listers, 7.3.4.3 database on HP-UX 11.0. In what way do statistics (or lack thereof) on non-indexed columns influence the CBO? I've searched high and wide for any info on this and came up with nothing, and, I can't think of a reason or example off the top of my head. And no, this isn't an OCP, homework (I wish I were that young), or interview question. Simply a question a friend called and asked me. Regards, Larry G.
