      Description

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a DECIMAL(2,1) DEFAULT 10000.1);

      correctly returns:

      +---------+------+--------------------------------------------+
      | Level   | Code | Message                                    |
      +---------+------+--------------------------------------------+
      | Warning | 1264 | Out of range value for column 'a' at row 1 |
      | Error   | 1067 | Invalid default value for 'a'              |
      +---------+------+--------------------------------------------+

      A similar script with a quoted default value:

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 (a DECIMAL(2,1) DEFAULT '10000.1');

      Does not produce an error.

      The default value is adjusted to the data type range:

      SHOW CREATE TABLE t1; +-------+---------------------------------------------------------------------------------------------+
      | Table | Create Table                                                                                |
      +-------+---------------------------------------------------------------------------------------------+
      | t1    | CREATE TABLE `t1` (
        `a` decimal(2,1) DEFAULT '9.9'
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
      +-------+---------------------------------------------------------------------------------------------+
