You have to love error messages some times. Today is was “ERROR 1289 (HY000): The ‘UNKNOWN’ feature is disabled;”
For those interested.
mysql> select version(); +-------------+ | version() | +-------------+ | 6.0.0-alpha | +-------------+ 1 row in set (0.00 sec) mysql> set session sql_mode=NO_ENGINE_SUBSTITUTION; Query OK, 0 rows affected (0.00 sec) mysql> create table T2 (id INT UNSIGNED NOT NULL) ENGINE=InnoDB; ERROR 1289 (HY000): The 'UNKNOWN' feature is disabled; you need MySQL built with 'UNKNOWN' to have it working
In this case it’s obviously something that’s not quite right, so being a good community contributor I raised a bug. You can read more at Bug #29373 .
MySQL values the contributions from the community, even as trivial as documentation or error messages. If you have an inquiry raise it at the forums or the lists , or if it’s obviously an issue raise it in the Bugs System
