Could you double check if you recreated all steps. I have checked that on ubuntu 10.10 maverick 32 / 64 bits and debian squeeze 64 bits with mysql 5.1.49 - all systems have same result. In 10.10 maverick desktop edition 32 bit with fresh install of mysql (no config changes) with just one db - 'test'. Debian one have no changes to config too. Important bit is: INSERT INTO `a_b` VALUES (12,4); select * from a_b where a_id = 11 and b_id = 4; Empty set (0.00 sec) and how create index fix it: create unique index index_a_b_on_both_id on a_b (a_id, b_id); select * from a_b where a_id = 11 and b_id = 4; +--+--+ | a_id | b_id | +--+--+ | 11 |4 | +--+--+ Kind Regards Marcin Grzymski -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-dfsg-5.1 in ubuntu. https://bugs.launchpad.net/bugs/727091 Title: Select on table with two colums cause empty result. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 727091] [NEW] Select on table with two colums cause empty result.
Public bug reported: Binary package hint: mysql-server-5.1 Table with two integer columns and separate indexes on each column can cause problems during select with conditions on both columns. Selecting with condition on one column works ok but multiple columns in same time generate empty result. Creating index on two columns fixes results from select. Version 5.0 works fine in that case. Looks like bug has been fixed in 5.1.54 + . http://bugs.mysql.com/bug.php?id=60231 ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: mysql-server-5.1 5.1.49-1ubuntu8.1 ProcVersionSignature: Ubuntu 2.6.35-25.44-generic 2.6.35.10 Uname: Linux 2.6.35-25-generic x86_64 NonfreeKernelModules: nvidia Architecture: amd64 Date: Tue Mar 1 10:42:40 2011 ProcEnviron: PATH=(custom, user) LANG=en_GB.utf8 SHELL=/bin/bash SourcePackage: mysql-5.1 ** Affects: mysql-dfsg-5.1 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug maverick -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-dfsg-5.1 in ubuntu. https://bugs.launchpad.net/bugs/727091 Title: Select on table with two colums cause empty result. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
