Wrong result for SELECT..WHERE LENGTH(decimal_10_1_column)!=3 AND decimal_10_1_column=1.10

    Details

      Description

      In this script:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL(10,1));
      		 
      INSERT INTO t1 VALUES (1.1);
      		 
      SELECT * FROM t1 WHERE LENGTH(a)!=3;
      		 
      SELECT * FROM t1 WHERE LENGTH(a)!=3 AND a=1.10;

      The first SELECT query correctly returns empty set, and the second SELECT query erroneously returns one row.
