      INSERT INTO t1 VALUES ('10.1');
      SELECT

        CAST(a AS DECIMAL(10,2)),
        CAST(a AS DECIMAL(10,3))
      FROM t1;
      

      +------+--------------------------+--------------------------+--------------------------+
      | a    | CAST(a AS DECIMAL(10,1)) | CAST(a AS DECIMAL(10,2)) | CAST(a AS DECIMAL(10,3)) |
      +------+--------------------------+--------------------------+--------------------------+
      | 10.1 |                     10.1 |                    10.01 |                   10.001 |
