Description
The script that is reported in MDEV-12377 causes a crash in 10.2.
This only happens if FETCH causes warnings. If I modify the data in the below script not to have the trailing 'x' character in the column t1.b, the crash goes away.
SET sql_mode=default; |
DROP TABLE IF EXISTS t1; |
DROP PROCEDURE IF EXISTS p1; |
|
|
CREATE TABLE t1 (a INT, b VARCHAR(10)); |
INSERT INTO t1 VALUES (10,'11x'); |
INSERT INTO t1 VALUES (10,'12x'); |
|
|
DELIMITER $$;
|
CREATE PROCEDURE p1() |
BEGIN
|
DECLARE cur1 CURSOR FOR SELECT b FROM t1; |
BEGIN |
DECLARE res int; |
OPEN cur1; |
FETCH cur1 INTO res; |
CLOSE cur1; |
END; |
END; |
$$
|
DELIMITER ;$$
|
|
|
CALL p1();
