From b4b7d941fea8b17bd0db2d30a74df6596101b4ed Mon Sep 17 00:00:00 2001 From: Igor Babaev Date: Tue, 15 Nov 2011 13:03:00 -0800 Subject: Fixed LP bug #889750. If the optimizer switch 'semijoin_with_cache' is set to 'off' then join cache cannot be used to join inner tables of a semijoin. Also fixed a bug in the function check_join_cache_usage() that led to wrong output of the EXPLAIN commands for some test cases. --- mysql-test/t/subselect4.test | 1 + 1 file changed, 1 insertion(+) (limited to 'mysql-test/t/subselect4.test') diff --git a/mysql-test/t/subselect4.test b/mysql-test/t/subselect4.test index db0433ce48e..98d47e7f3ea 100644 --- a/mysql-test/t/subselect4.test +++ b/mysql-test/t/subselect4.test @@ -6,6 +6,7 @@ drop table if exists t1,t2,t3,t4,t5,t6; set @subselect4_tmp= @@optimizer_switch; set optimizer_switch='semijoin=on,firstmatch=on,loosescan=on'; +set optimizer_switch='semijoin_with_cache=on'; set optimizer_switch='mrr=on,mrr_sort_keys=on,index_condition_pushdown=on'; --echo # -- cgit v1.2.1
