Delete a catalog

You can use the DROP CATALOG [IF EXISTS] external_catalog_name; statement to delete a catalog that is no longer in use.

When you delete a catalog, if you specify IF EXISTS, no error is returned even if the catalog does not exist. If you do not specify IF EXISTS, an error is returned.

Here is an example:

obclient> DROP CATALOG IF EXISTS test_odps_catalog;
