    Description

      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 AS SELECT 12345678900 AS c1, COALESCE(12345678900) AS c2;
      SELECT * FROM t1;
      SHOW CREATE TABLE t1;
      

      +-------------+------------+
      | c1          | c2         |
      +-------------+------------+
      | 12345678900 | 2147483647 |
      +-------------+------------+

      | Table | Create Table                                                                                                   |
      +-------+----------------------------------------------------------------------------------------------------------------+
      | t1    | CREATE TABLE `t1` (
        `c1` bigint(11) NOT NULL,
        `c2` int(11) NOT NULL
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
      +-------+---------------------------------------------------------------------------------------------------------------
      

      The expected result to create a BIGINT column for both expressions, and return 12345678900 for both columns.
