NDB_SHOW_TABLES(1)

NAME
ndb_show_tables - display list of NDB tables

SYNOPSIS

ndb_show_tables [options]

DESCRIPTION

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 NDB Cluster Disk Data objects as well.

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

    Command-Line Format | --ndb-connectstring=connection-string
    Type | String
    Default Value | [none]

    Set connect string for connecting to ndb_mgmd. Syntax: "[nodeid=id;][host=]hostname[:port]". Overrides entries in NDB_CONNECTSTRING and my.cnf.

    Command-Line Format | --ndb-mgmd-host=connection-string
    Type | String
    Default Value | [none]

    Same as --ndb-connectstring.

    • --ndb-nodeid
    Command-Line Format | --ndb-nodeid=#
    Type | Integer

    Set node ID for this node, overriding any ID set by --ndb-connectstring.

    • --ndb-optimized-node-selection
    Command-Line Format | --ndb-optimized-node-selection

    Print program argument list and exit.

    • --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.

    • --usage
    Command-Line Format | --usage

    Display help text and exit; same as --help.

    • --version
    Command-Line Format | --version

    Display version information and exit.

    Note

    Only user-created NDB 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 ndb_select_all(1)).

Prior to NDB 7.5.18 and 7.6.14, this program printed NDBT_ProgramExit - status upon completion of its run, due to an unnecessary dependency on the NDBT testing library. This dependency is has now been removed, eliminating the extraneous output.
