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.

In NDB 7.6 and earlier, this program printed NDBT_ProgramExit − status upon completion of its run, due to an unnecessary dependency on the NDBT testing library. This dependency has been removed in NDB 8.0, eliminating the extraneous output.
