To get Check object properties, users can be a member of the public fixed server role.
To set Check object properties and run the Alter method, users must have ALTER permission on the parent table or column, or be a member of the db_owner fixed database role.
To create a check constraint, users must have ALTER permission on the parent table, or be a member of the db_owner fixed database role.
To drop a check constraint, users must have ALTER permission on the parent table, or be a member of the db_owner fixed database role.
