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/subselect3.test | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'mysql-test/t/subselect3.test') diff --git a/mysql-test/t/subselect3.test b/mysql-test/t/subselect3.test index f3faf44289e..e0f62a29465 100644 --- a/mysql-test/t/subselect3.test +++ b/mysql-test/t/subselect3.test @@ -3,7 +3,7 @@ drop table if exists t0, t1, t2, t3, t4, t5, t11, t12, t21, t22; --enable_warnings set @subselect3_tmp= @@optimizer_switch; -set optimizer_switch='semijoin=on,firstmatch=on,loosescan=on'; +set optimizer_switch='semijoin=on,firstmatch=on,loosescan=on,semijoin_with_cache=on'; # # 1.
