A method and apparatus for locking a database table having a plurality of partitions. In various embodiments, lock status codes are maintained for both a database table and for the partitions of the database table. The partition locks do not need to be updated when a lock is granted for the database table since a separate table lock status code is maintained. The separate table lock status code improves database application performance and simplifies programming of explicit lock operations.
