[shangyanwen]

Describe the problem

SET sql_mode = 'NO_ENGINE_SUBSTITUTION';
CREATE TABLE t1 (
  id int NOT NULL DEFAULT '0',
  a  varchar(10) NOT NULL,
  b  varchar(10),
  c  varchar(10),
  d  timestamp NOT NULL,
  PRIMARY KEY (id, a)
)engine=tianmu;

CREATE TABLE t2 (
  fubar_id         int  NOT NULL DEFAULT '0',
  last_change_time datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  PRIMARY KEY  (fubar_id)
)engine=tianmu;

DELIMITER |
CREATE TRIGGER fubar_change
  AFTER UPDATE ON t1
    FOR EACH ROW
      BEGIN
        INSERT INTO t2 (fubar_id, last_change_time)
          SELECT DISTINCT NEW.id AS fubar_id, NOW() AS last_change_time
            FROM t1 WHERE (id = NEW.id) AND (OLD.c != NEW.c)
        ON DUPLICATE KEY UPDATE
          last_change_time =
            IF((fubar_id = NEW.id)AND(OLD.c != NEW.c),NOW(),last_change_time);
      END|

DELIMITER ;

INSERT INTO t1 (id,a, b,c,d) VALUES
 (1,'a','b','c',now()),(2,'a','b','c',now());

UPDATE t1 SET c='Bang!' WHERE id=1;

##Incorrect test results
SELECT fubar_id FROM t2;
Empty set (0.00 sec)

DROP TABLE t1,t2;
SET sql_mode = default;

Expected behavior

#Correct test results（note:Innodb test verification, test results are as follows）
SELECT fubar_id FROM t2;
fubar_id
1
