You can delete an unused database from the DLI console: when a database is no longer needed, such as after a test database has completed testing; if a database has errors or anomalies that cannot be fixed; when there is a need to reorganize the data structure, such as by modifying table designs; or if a database is idle and has no practical use.
This section describes how to delete a database on the DLI management console.
If a database or table is deleted, it cannot be recovered. Exercise caution when performing this operation.
You cannot delete databases that contain tables. To delete a database containing tables, delete the tables first.
