hi! to speed up queries i have created a bitmap index on a column that contains 2 chars as a maximum. to my surprise the bitmap index does not make the query quicker than the 'usual' B-tree index, though there are only bout 100 different values in half a million rows.
has n.e.one got experience with bitmap indices? are there any further poosibilities to adapt them when creating??? tia & bye daniel -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Daniel Wisser INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- 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).
