Test case:
|
SET use_stat_tables=PREFERABLY;
|
SET optimizer_use_condition_selectivity=2;
|
|
CREATE TABLE t1 (a INT) ENGINE=MyISAM;
|
INSERT INTO t1 VALUES (1);
|
|
CREATE TABLE t2 (b INT, INDEX(b)) ENGINE=MyISAM;
|
INSERT INTO t2 VALUES (2),(3);
|
|
CREATE TABLE t3 (c INT) ENGINE=MyISAM;
|
INSERT INTO t3 VALUES (4),(5);
|
|
ANALYZE TABLE t1, t2, t3;
|
|
SELECT * FROM t1, t2, t3 WHERE a = 4 AND c = b;
|
EXPLAIN also crashes.
