Hello, Basically I want to know if this is a good query for indexing.
I have the following query: select count(1) as count from session where last >= DATE_SUB(NOW(), INTERVAL :from SECOND) Is it safe to assume that the expression calling the function DATE_SUB is evaluated just once to a fixed date?
