ndb_select_count

NDB_SELECT_COUNT()														NDB_SELECT_COUNT()

NAME

       ndb_select_count - print row counts for NDB tables

SYNOPSIS

       ndb_select_count [-c connect_string] -d db_name tbl_name[ tbl_name2[ ...]]

DESCRIPTION

       ndb_select_count prints the number of rows in one or more NDB tables. With a single table, the result is equivalent to that obtained by
       using the MySQL statement SELECT COUNT(*) FROM tbl_name.
	       Usage

	   ndb_select_count [-c connect_string] -ddb_name tbl_name[, tbl_name2[, ...]]

       The following table includes options that are specific to the MySQL Cluster native backup restoration program ndb_select_count. Additional
       descriptions follow the table. For options common to most MySQL Cluster programs (including ndb_select_count), see Options Common to MySQL
       Cluster Programs(1).

       You can obtain row counts from multiple tables in the same database by listing the table names separated by spaces when invoking this
       command, as shown under Sample Output.
	       Sample Output

	   shell> ./ndb_select_count -c localhost -d ctest1 fish dogs
	   6 records in table fish
	   4 records in table dogs
	   NDBT_ProgramExit: 0 - OK
