Hi, had a bit of weird result for a query: SELECT id FROM spectrum_match WHERE search_id in (788,694,693,685) AND rescored IS NOT NULL and dynamic_rank = true ORDER BY ID; returns (among some 127K other lines): ... 32694548 32694860 ... But if I change the query to: SELECT id FROM spectrum_match WHERE search_id in (788,694,693,685) AND rescored IS NOT NULL and dynamic_rank = true and id= 32694801; I get 32694801 which is omitted from the previous result. The database is running under windows (I know that's bad - but we had reasons...). It only became apparent after we made a copy of the database and run it under Linux (Debian wheezy). There the first query returned 136k lines and this id was the first difference. Does anybody has an idea what is going on? It's postgresql 9.2.1 running under a windows 2008 R2 server Lutz -- Lutz Fischer lfischer@xxxxxxxxxxxxxxxxxx +44 131 6517057 The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
