Require Primary Key

In almost all cases, each table needs a primary key.

In MySQL, the InnoDB storage engine always creates a primary key if you didn't specify it explicitly or didn't create a unique key, thus making an extra column you don't have access to.


How the rule works

Bytebase considers this rule to be violated if the SQL tries to create a no primary key table or drop the primary key. If the SQL drops all columns in the primary key, Bytebase also considers that this SQL drops the primary key.
