Thanks for the prompt reply.
Description: Getting incomplete data set while querying InnoDB table. Looks good with MyIsam on the same version. We tried only with Version: 5.1.39 and 5.1.40 and both produce the same incompleted data (date) set. To make it more clear: mysql> select * from bugtest; +------------+ | dt | +------------+ | 2009-10-25 | | 2009-10-26 | | 2009-10-27 | +------------+ 3 rows in set (0.00 sec) mysql> select * from bugtest where dt >= '20091025'; +------------+ | dt | +------------+ | 2009-10-26 | | 2009-10-27 | +------------+ **** NOTE: 2009-10-25 is missing from the above query **** 2 rows in set (0.00 sec) mysql> select * from bugtest where dt >= '2009-10-25'; +------------+ | dt | +------------+ | 2009-10-25 | | 2009-10-26 | | 2009-10-27 | +------------+ 3 rows in set (0.00 sec) We have another server with MySQL 5.0.45, no problems with that innodb table. Please let us know how to resolve this. How to repeat: mysql> create table bugtest (dt date not null, primary key (dt) ) engine=innodb; Query OK, 0 rows affected (0.00 sec) mysql> show create table bugtest\G *************************** 1. row *************************** Table: bugtest Create Table: CREATE TABLE `bugtest` ( `dt` date NOT NULL, PRIMARY KEY (`dt`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 1 row in set (0.00 sec) mysql> insert into bugtest values ('20091025'),('20091026'),('20091027'); Query OK, 3 rows affected (0.00 sec) Records: 3 Duplicates: 0 Warnings: 0 mysql> select * from bugtest; +------------+ | dt | +------------+ | 2009-10-25 | | 2009-10-26 | | 2009-10-27 | +------------+ 3 rows in set (0.00 sec) mysql> select * from bugtest where dt >= '20091025'; +------------+ | dt | +------------+ | 2009-10-26 | | 2009-10-27 | +------------+ 2 rows in set (0.00 sec) mysql> select * from bugtest where dt >= '2009-10-25'; +------------+ | dt | +------------+ | 2009-10-25 | | 2009-10-26 | | 2009-10-27 | +------------+ 3 rows in set (0.00 sec) mysql> select version(); +------------------+ | version() | +------------------+ | 5.1.40-community | +------------------+ 1 row in set (0.01 sec) Suggested fix: Don't Know !
