MySQL 5.7 Reference Manual  /  ...  /  ndb_delete_all — Delete All Rows from an NDB Table

21.5.9 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.

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