Constraint names on primary keys and default values are generated with random character sequences at the end to make them unique. If you delete the table and re-create it, the names don’t match the ones from the first time around.
This makes life difficult if you are using a database compare tool (e.g. redgate sql compare) to do migration scripts since user A’s db constraint names will be different than user B’s db constraint names.
Foreign key & index naming doesn’t add any random characters.
Is there a way to change the naming scheme so that the random sequences aren’t used?
