          Description

          DROP TABLE IF EXISTS t1;
CREATE TABLE t1 (a ENUM('0x'));
INSERT INTO t1 VALUES ('0x');
SELECT a IS TRUE AS a0, COALESCE(a) IS TRUE AS a1, LEAST(a,a) IS TRUE AS a2, (SELECT a FROM t1) IS TRUE AS a3 FROM t1;

          returns:

          +----+----+----+----+
| a0 | a1 | a2 | a3 |
+----+----+----+----+
|  1 |  0 |  1 |  0 |
+----+----+----+----+

          Expect to get the same result for all columns.
