Hi,

Is there any idea how many indexes per table can use optimizer. In other words when I'm selecting some data from one table_1 and have 2 indexes first on field_1 second on filed_2 example:

select * from table_1 where field_1 = 5 and field_2 = 'ttt'

in this case is optimizer uses all indexes on table_1 or it uses only one index?

TIA
Laert
