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.

The following table includes options that are specific to ndb_delete_all. Additional descriptions follow the table. For options common to most NDB Cluster programs (including ndb_delete_all), see Options Common to NDB Cluster Programs(1).
