How can I optimize this query

select * from table where col1 = 5 && col2 = 15;

If I  know that col2 I have 150000 rows and col1 I have just 100
rows, I know that because I save that data in another table.

How can I do for search first where is minus number of result?


The two columns are indexes.

Try making it

select * from table where col1 = 5 and +col2 = 15;

The unary plus in front of col2 disqualifies it for use in an index, so SQLite is likely to use an index on col1.
