From ff23f5360ee328bd6adb14436e68e080cfe1d110 Mon Sep 17 00:00:00 2001 From: Sergey Glukhov Date: Mon, 28 Mar 2011 12:28:30 +0400 Subject: Bug#11766424 59527: DECIMAL_BIN_SIZE: ASSERTION `SCALE >= 0 && PRECISION > 0 && SCALE <= PRE Assertion happens due to missing initialization of unsigned_flag for Item_func_set_user_var object. It leads to incorrect calculation of decimal field size. The fix is to add initialization of unsigned_flag. mysql-test/r/variables.result: test case mysql-test/t/variables.test: test case sql/item_func.cc: add initialization of unsigned_flag. --- mysql-test/t/variables.test | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'mysql-test/t/variables.test') diff --git a/mysql-test/t/variables.test b/mysql-test/t/variables.test index 383bdfc79a9..8f111e7cf3b 100644 --- a/mysql-test/t/variables.test +++ b/mysql-test/t/variables.test @@ -1298,6 +1298,19 @@ SET @@global.key_cache_block_size=0; # select @@max_long_data_size; +--echo # +--echo # Bug#11766424 59527: DECIMAL_BIN_SIZE: ASSERTION `SCALE >= 0 && PRECISION > 0 && SCALE <= PRE +--echo # + +CREATE TABLE t1(f1 DECIMAL(1,1) UNSIGNED); +INSERT INTO t1 VALUES (0.2),(0.1); +SELECT 1 FROM t1 GROUP BY @a:= (SELECT ROUND(f1) FROM t1 WHERE @a=f1); +DROP TABLE t1; + +CREATE TABLE t1 AS SELECT @a:= CAST(1 AS UNSIGNED) AS a; +SHOW CREATE TABLE t1; +DROP TABLE t1; + # cleanup SET @@global.max_binlog_cache_size=DEFAULT; SET @@global.max_join_size=DEFAULT; -- cgit v1.2.1
