Description
This is the test case that was discussed on IRC. It looks similar to MDEV-4942, but the fix for the latter is already in the tree, and this one still fails.
CREATE TABLE t1 (a1 INT, b1 INT NOT NULL) ENGINE=MyISAM; |
INSERT INTO t1 VALUES (1, 10), (2, 11); |
|
|
CREATE TABLE t2 (dt DATETIME NOT NULL, a2 INT, b2 INT) ENGINE=MyISAM; |
INSERT INTO t2 VALUES ('2006-10-08 09:34:54', 1, 100), ('2001-01-19 01:04:43', 2, 200); |
|
|
SELECT * FROM t1 LEFT JOIN t2 ON a1 = a2 WHERE ( dt IS NULL OR b1 IS NULL ) AND b2 IS NULL; |
