NDB_DELETE_ALL(1)

NAME
ndb_delete_all - delete all rows from an NDB table

SYNOPSIS

ndb_delete_all options

DESCRIPTION

ndb_delete_all deletes all rows from the given NDB table. In some cases, this can be much faster than DELETE or even TRUNCATE TABLE. Usage

    ndb_delete_all -c connection_string tbl_name -d db_name

This deletes all rows from the table named tbl_name in the database named db_name. It is exactly equivalent to executing TRUNCATE db_name.tbl_name in MySQL.

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