Igor Babaev 746dbbe583 Fixed LP bug #917990. ... If the expression for a derived table of a query contained a LIMIT clause the estimate of the number of rows in this derived table returned by the EXPLAIN command could be badly off since the optimizer ignored the limit number from the LIMIT clause when getting the estimate. The call of the method SELECT_LEX_UNIT->set_limit added in the code of mysql_derived_optimize() will be needed also in maria-5.5 where parameters in the LIMIT clause are supported.		2012-01-18 03:31:20 -08:00
