From 7f6a8164846da34a822e8f844d6ec9e1da3af412 Mon Sep 17 00:00:00 2001 From: unknown Date: Thu, 19 Jul 2007 20:21:23 +0400 Subject: Bug#29850: Wrong charset of GROUP_CONCAT result when the select employs a temporary table. The result string of the Item_func_group_concat wasn't initialized in the copying constructor of the Item_func_group_concat class. This led to a wrong charset of GROUP_CONCAT result when the select employs a temporary table. The copying constructor of the Item_func_group_concat class now correctly initializes the charset of the result string. mysql-test/t/func_gconcat.test: Added a test case for the bug#29850: Wrong charset of the GROUP_CONCAT result when the select employs a temporary table. mysql-test/r/func_gconcat.result: Added a test case for the bug#29850: Wrong charset of the GROUP_CONCAT result when the select employs a temporary table. sql/item_sum.cc: Bug#29850: Wrong charset of GROUP_CONCAT result when the select employs a temporary table. The copying constructor of the Item_func_group_concat class now correctly initializes the charset of the result string. --- mysql-test/r/func_gconcat.result | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'mysql-test/r/func_gconcat.result') diff --git a/mysql-test/r/func_gconcat.result b/mysql-test/r/func_gconcat.result index 8b71ad1940e..35487c25ae3 100644 --- a/mysql-test/r/func_gconcat.result +++ b/mysql-test/r/func_gconcat.result @@ -810,4 +810,13 @@ LENGTH( GROUP_CONCAT( a ) ) 65535 SET group_concat_max_len= DEFAULT; DROP TABLE t1, t2, t3; +set names latin1; +create table t1 (id int, name varchar(20)) DEFAULT CHARSET=utf8; +insert into t1 (id, name) values (1, "óra"); +insert into t1 (id, name) values (2, "óra"); +select b.id, group_concat(b.name) from t1 a, t1 b group by b.id; +id group_concat(b.name) +1 óra,óra +2 óra,óra +drop table t1; End of 5.0 tests -- cgit v1.2.1
