This is a temporary table (with no indexes) that gets created in the same transaction block as the SELECT gets run, but I tried creating an index on the ean column anyway with no luck:
CREATE INDEX ean_idx ON TMPTABLE USING btree (ean); SELECT DISTINCT ON (ean) ean, count(*) FROM TMPTABLE WHERE code NOT IN (SELECT code FROM stock_deleted) AND ean IS NOT NULL GROUP BY ean; Still returns: 3246576919422 2 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marcin Stêpnicki Sent: Tuesday, 20 February 2007 23:34 To: pgsql-sql@postgresql.org Subject: Re: [SQL] DISTINCT ON not working...? Wild guess - have you tried reindexing this table? I haven't seen corrupted indexes since 7.1, though - it usually means subtle hardware problems. *******************Confidentiality and Privilege Notice******************* The material contained in this message is privileged and confidential to the addressee.
