 Description   

In this script:

DROP TABLE IF EXISTS t1;
 
CREATE TABLE t1 (a DATETIME);
 
INSERT INTO t1 VALUES ('2000-09-12 00:00:00'), ('2007-04-25 05:08:49');
 
SELECT * FROM t1 WHERE a>TIME'00:00:00';
 
SELECT * FROM t1 WHERE a>TIME('00:00:00');

the first SELECT query correctly returns empty set, and the second SELECT query erroneously returns two rows:

+---------------------+
 
| a                   |
 
+---------------------+
 
| 2000-09-12 00:00:00 |
 
| 2007-04-25 05:08:49 |
 
+--------------------
