18.4.23 ndb_show_tables — Display List of NDB Tables

ndb_show_tables displays a list of all NDB database objects in the cluster. By default, this includes not only both user-created tables and NDB system tables, but NDB-specific indexes, internal triggers, and MySQL Cluster Disk Data objects as well.

The following table includes options that are specific to the MySQL Cluster native backup restoration program ndb_show_tables. Additional descriptions follow the table. For options common to most MySQL Cluster programs (including ndb_show_tables), see Section 18.4.26, “Options Common to MySQL Cluster Programs — Options Common to MySQL Cluster Programs”.

ndb_show_tables [-c connection_string]
  • --database, -d

    Specifies the name of the database in which the tables are found.

  • --loops, -l

    Specifies the number of times the utility should execute. This is 1 when this option is not specified, but if you do use the option, you must supply an integer argument for it.

  • --parsable, -p

    Using this option causes the output to be in a format suitable for use with LOAD DATA INFILE.

  • --show-temp-status

    If specified, this causes temporary tables to be displayed.

  • --type, -t

    Can be used to restrict the output to one type of object, specified by an integer type code as shown here:

    • 1: System table

    • 2: User-created table

    • 3: Unique hash index

    Any other value causes all NDB database objects to be listed (the default).

  • --unqualified, -u

    If specified, this causes unqualified object names to be displayed.


Only user-created MySQL Cluster tables may be accessed from MySQL; system tables such as SYSTAB_0 are not visible to mysqld. However, you can examine the contents of system tables using NDB API applications such as ndb_select_all (see Section 18.4.21, “ndb_select_all — Print Rows from an NDB Table”).
