MySQL 5.7 Reference Manual

21.5.12 ndb_drop_table — Drop an NDB Table

ndb_drop_table drops the specifiedNDB table. (If you try to use this on a table created with a storage engine other thanNDB, the attempt fails with the error723: No such table exists.) This operation is extremely fast; in some cases, it can be an order of magnitude faster than using a MySQLDROP TABLE statement on anNDB table.

Usage

ndb_drop_table -cconnection_stringtbl_name -ddb_name
