SET optimizer_use_condition_selectivity = 3; |
|
CREATE TABLE t1 (pk INT PRIMARY KEY, a INT) ENGINE=MyISAM; |
INSERT INTO t1 VALUES |
(1,4),(2,6),(3,3),(4,5),(5,3),(6,4),(7,2),(8,9);
|
|
CREATE TABLE t2 (b INT) ENGINE=MyISAM; |
INSERT INTO t2 VALUES (1),(7); |
|
SELECT 1 FROM t1, t2 WHERE pk = 6 AND a = 2 AND b = 10; |
Also reproducible with InnoDB.
Reproducible with the default optimizer_switch as well as with all OFF values.
EXPLAIN also crashes.
