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.

Table 23.47. Command−line options used with the program ndb_show_tables
Usage

ndb_show_tables [−c connection_string]

−−character−sets−dir

Directory containing character sets.

−−connect−retries

Number of times to retry connection before giving up.

−−connect−retry−delay

Number of seconds to wait between attempts to contact management server.

−−connect−string

Same as −−ndb−connectstring.

−−core−file

Write core file on error; used in debugging.

−−database, −d Specifies the name of the database in which the desired table is found. If this option is given, the name of a table must follow the database name.

If this option has not been specified, and no tables are found in the TEST_DB database, ndb_show_tables issues a warning.

−−defaults−extra−file

Read given file after global files are read.

−−defaults−file

Read default options from given file only.

−−defaults−group−suffix

Also read groups with concat(group, suffix).

−−help

Display help text and exit.

−−login−path

Read given path from login file.

−−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.

−−ndb−connectstring

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

−−ndb−mgmd−host

Same as −−ndb−connectstring.

−−ndb−nodeid

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

−−ndb−optimized−node−selection

Enable optimizations for selection of nodes for transactions. Enabled by default; use −−skip−ndb−optimized−node−selection to disable.

−−no−defaults

Do not read default options from any option file other than login file.

−−parsable, −p Using this option causes the output to be in a format suitable for use with LOAD DATA.

−−print−defaults

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

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

−−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 8.0.20, 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, eliminating the extraneous output.
