Hi all We are having a weird problem with some queries which are not using some indexes in date fields.
Query-1 SELECT [field list] FROM tableX WHERE dateField = [any date expression or constant value] Query-2 SELECT [field list] FROM tableX WHERE dateField <= [any date expression or constant value] We have an index for dateField in tableX. However Query-1 is using the index but Query-2 is not. We have tested a lot of different combinations and every time we use any of these operators <=, <, >, >= Mysql stop using the index. We are using Mysql 4.1.12 binary distribution running on linux. Any help will be really appreciated.
