17.4.22. 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 17.4.25, "Options Common to MySQL Cluster Programs — Options Common to MySQL Cluster Programs".

`--database=string`, `-d`	Specifies the database in which the table is found	All MySQL 5.6 based releases
`--loops=#`, `-l`	Number of times to repeat output	All MySQL 5.6 based releases
`--type=#`, `-t`	Limit output to objects of this type	All MySQL 5.6 based releases
`--unqualified`, `-u`	Do not qualify table names	All MySQL 5.6 based releases
`--parsable`, `-p`	Return output suitable for MySQL LOAD DATA INFILE statement	All MySQL 5.6 based releases

Usage

ndb_show_tables [-c connect_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.

Note

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 17.4.19, "ndb_select_all — Print Rows from an NDB Table").
