I have a query that requires a where statement on a calculated value:
select * from table where date( timestamp ) = ?
An explain on this query yields the expected ALL select type, which is not ideal. Using MySQL, what’s the best way to optimize this?
Another option might be to rewrite the query such that the calculations are all done on the other side of the equation. For example:
In this query, “some date” would be midnight of that date.
