2016-01-29 08:45:15 7f5b11b09700 Error in foreign key constraint of table auditdb/tb_test:
foreign key(`action_id`) references `tb_tab1` (`action_id`)):
Cannot find an index in the referenced table where the
referenced columns appear as the first columns, or column types
in the table and the referenced table do not match for constraint.
Note that the internal storage type of ENUM and SET changed in
tables created with >= InnoDB-4.1.12, and such columns in old tables
cannot be referenced by such columns in new tables.
