Hi
i found a strange problem . when i using index for 'select' , i
got a slower result than without index .
i have a tabe :
create table geo_query (
`id` int(10) unsigned not null auto_increment ,
`start` bigint(20) unsigned not null ,
`end`
.
Index hints are rarely ever needed. It's best to stay away from them unless
you know exactly what's going on under the hood :-)
