    Description

      Testcase:

      CREATE TABLE t1 (a YEAR(2));
      		 
      INSERT INTO t1 VALUES (0);
      		 
      SELECT a, NULLIF(a,2001), NULLIF(2001,a) FROM t1;
      		 
      DROP TABLE t1;

      Expected result:

      a	NULLIF(a,2001)	NULLIF(2001,a)
      		 
      00	00	2001

      Actual result:

      a	NULLIF(a,2001)	NULLIF(2001,a)
      		 
      00	0	2001
