LP:869104 - CREATE TABLE ... SELECT can result in column type "null"

        Details

        • Type: Bug

          Description

          CREATE TABLE t1 ENGINE = INNODB AS SELECT IF(NULL IS NOT NULL, NULL, NULL);
          SHOW CREATE TABLE t1;

          Create Table: CREATE TABLE `t1` (
          `IF(NULL IS NOT NULL, NULL, NULL)` null DEFAULT NULL
          ) ENGINE=InnoDB DEFAULT CHARSET=latin1

          Note the column type "null". This is not valid in CREATE TABLE, so for example
          a mysqldump including such a table will not be able to re-create the table.

          This is MySQL bug#54394: http://bugs.mysql.com/bug.php?id=54394
