--- Comment #20 from Nik Everett <[email protected]> --- (In reply to comment #19) > (Hopefully $dbr->estimateRowCount() executes in O(1) time!) For MySQL, PostgreSQL, and MSSQL it is O(1) because it uses an explain. Looks like Sqllite and Oracle do it with a COUNT(*) though. I know Oracle hides its explain output behind obtuse views that you may or may not have access to. I'm not sure about Sqllite. -- You are receiving this mail because: You are the assignee for the bug.
