25.5.11 ndb_drop_table — Drop an NDB Table

ndb_drop_table drops the specified NDB table. (If you try to use this on a table created with a storage engine other than NDB, the attempt fails with the error 723: No such table exists.) This operation is extremely fast; in some cases, it can be an order of magnitude faster than using a MySQL DROP TABLE statement on an NDB table.

Usage

ndb_drop_table -c connection_string tbl_name -d db_name

Options that can be used with ndb_drop_table are shown in the following table. Additional descriptions follow the table.
