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
