From 272bb6b5856a7f033e6826ba5a96b1ca52aabb12 Mon Sep 17 00:00:00 2001 From: unknown Date: Mon, 8 Oct 2007 12:46:38 +0500 Subject: Bug#27580 SPACE() function collation bug? Problem: when character_set_connection=utf8, mixing SPACE() with a non-Unicode column (e.g. for concat) produced "illegal mix of collations" error. Fix: Item_string() corresponding to space character is now created using "ASCII" repertoire. Previously it was incorrectly created using "UNICODE" repertoure, which didn't allow to convert results of SPACE() to a non-Unicode character set. mysql-test/include/ctype_common.inc: - Adding test for bug#27580 - Restoring previous values of character_set_client and character_set_results, because ctype_common.inc now changes them when doing "set names utf8" in the test for bug#27580 mysql-test/r/ctype_big5.result: Adding test mysql-test/r/ctype_cp1250_ch.result: Adding test mysql-test/r/ctype_euckr.result: Adding test mysql-test/r/ctype_gb2312.result: Adding test mysql-test/r/ctype_gbk.result: Adding test mysql-test/r/ctype_uca.result: Adding test mysql-test/r/ctype_ucs.result: Adding test mysql-test/t/ctype_cp1250_ch.test: Adding test mysql-test/t/ctype_ucs.test: Adding test sql/item_create.cc: Item for SQL function SPACE() is now created with ASCII repertoire, to allow automatic conversion from UTF8 to column's character set e.g. for CONCAT(). --- mysql-test/include/ctype_common.inc | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'mysql-test/include') diff --git a/mysql-test/include/ctype_common.inc b/mysql-test/include/ctype_common.inc index 202c508a9c9..b9bd7869967 100644 --- a/mysql-test/include/ctype_common.inc +++ b/mysql-test/include/ctype_common.inc @@ -13,6 +13,8 @@ SET @safe_character_set_server= @@character_set_server; SET @safe_collation_server= @@collation_server; +SET @safe_character_set_client= @@character_set_client; +SET @safe_character_set_results= @@character_set_results; SET character_set_server= @test_character_set; SET collation_server= @test_collation; CREATE DATABASE d1; @@ -51,8 +53,22 @@ SELECT c1 as want1result from t1 where c1 like 'locatio%'; SELECT c1 as want1result from t1 where c1 like 'location%'; DROP TABLE t1; +# +# Bug#27580 SPACE() function collation bug? +# +set names utf8; +create table t1 ( + name varchar(10), + level smallint unsigned); +show create table t1; +insert into t1 values ('string',1); +select concat(name,space(level)), concat(name, repeat(' ',level)) from t1; +drop table t1; + DROP DATABASE d1; # Restore settings USE test; SET character_set_server= @safe_character_set_server; SET collation_server= @safe_collation_server; +SET character_set_client= @safe_character_set_client; +SET character_set_results= @safe_character_set_results; -- cgit v1.2.1
