MySQL Cluster NDB 6.1-7.1  /  MySQL Cluster Programs  /  ndb_delete_all — Delete All Rows from an NDB Table

6.9 ndb_delete_all — Delete All Rows from an NDB Table

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 MySQL Cluster programs (including ndb_delete_all), see Section 6.26, “Options Common to MySQL Cluster Programs — Options Common to MySQL Cluster Programs”.
