      Description

      This script:

      CREATE OR REPLACE TABLE t1 (a INT, KEY(a));
      INSERT INTO t1 VALUES (1),(2),(3);
      SELECT * FROM t1 WHERE a BETWEEN NAME_CONST('x',1) AND NAME_CONST('y',2);
      

      returns a correct result:

      +------+
      | a    |
      +------+
      |    1 |
      |    2 |
      +------+
      

      Now I change the name in the second NAME_CONST() from 'x' to 'y', the script returns a wrong result:

      CREATE OR REPLACE TABLE t1 (a INT, KEY(a));
      INSERT INTO t1 VALUES (1),(2),(3);
      SELECT * FROM t1 WHERE a BETWEEN NAME_CONST('x',1) AND NAME_CONST('x',2);
      

      +------+
      | a    |
      +------+
      |    1 |
      +------+
