Hello, a friend of mine has got a problem:
in a SELECT with a condition 'WHERE foo IN (1,2,3,4,...)' with a large list within. The optimizer choose a rewrite to many OR's and a bitmap index scan on the index, no problem, fast. But if the list increase the planner choose an seq-scan. The amount of values in the list is about 200 and the table has about 250.000 rows. How can we avoid the seq-scan? Andreas, thx in advance. -- Andreas Kretschmer Kontakt: Heynitz: 035242/47150, D1: 0160/7141639 (mehr: -> Header) GnuPG-ID: 0x3FFF606C, privat 0x7F4584DA http://wwwkeys.de.pgp.net ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
