25.5.27 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 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.

Usage

ndb_show_tables [-c connection_string]

--character-sets-dir
Command-Line Format --character-sets-dir=path
Directory containing character sets.
--connect-retries
Command-Line Format --connect-retries=#
Type Integer
Default Value 12
Minimum Value 0
Maximum Value 12

--core-file
Command-Line Format --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
Command-Line Format --defaults-extra-file=path
Type String
Default Value [none]
Read given file after global files are read.
--defaults-file
Command-Line Format --defaults-file=path
Type String
Default Value [none]
Read default options from given file only.
--defaults-group-suffix
Command-Line Format --defaults-group-suffix=string
Type String
Default Value [none]
Also read groups with concat(group, suffix).
--help
Command-Line Format --help
Display help text and exit.
--login-path
Command-Line Format --login-path=path
Type String
Default Value [none]
Read given path from login file.
--no-login-paths
Command-Line Format --no-login-paths
Skips reading options from the login path 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
Command-Line Format --ndb-connectstring=connection_string
Type String
Default Value [none]
Set connection string for connecting to ndb_mgmd. Syntax: [nodeid=id;][host=]hostname[:port]. Overrides entries in NDB_CONNECTSTRING and my.cnf.
--ndb-mgm-tls
Command-Line Format --ndb-mgm-tls=level
Type Enumeration
Default Value relaxed
Valid Values
relaxed
strict

Sets the level of TLS support required to connect to the management server; one of relaxed or strict. relaxed (the default) means that a TLS connection is attempted, but success is not required; strict means that TLS is required to connect.
--ndb-mgmd-host
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
Default Value [none]
Set node ID for this node, overriding any ID set by --ndb-connectstring.
--ndb-optimized-node-selection
Command-Line Format --ndb-optimized-node-selection
Enable optimizations for selection of nodes for transactions. Enabled by default; use --skip-ndb-optimized-node-selection to disable.
--ndb-tls-search-path
Command-Line Format --ndb-tls-search-path=list
Type Path name
Default Value (Unix) $HOME/ndb-tls
Default Value (Windows) $HOMEDIR/ndb-tls
Specify a list of directories to search for a CA file. On Unix platforms, the directory names are separated by colons (:); on Windows systems, the semicolon character (;) is used as the separator. A directory reference may be relative or absolute; it may contain one or more environment variables, each denoted by a prefixed dollar sign ($), and expanded prior to use.
Searching begins with the leftmost named directory and proceeds from left to right until a file is found. An empty string denotes an empty search path, which causes all searches to fail. A string consisting of a single dot (.) indicates that the search path limited to the current working directory.
If no search path is supplied, the compiled-in default value is used. This value depends on the platform used: On Windows, this is \ndb-tls; on other platforms (including Linux), it is $HOME/ndb-tls. This can be overridden by compiling NDB Cluster using -DWITH_NDB_TLS_SEARCH_PATH.
--no-defaults
Command-Line Format --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
Command-Line Format --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
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 Section 25.5.25, “ndb_select_all — Print Rows from an NDB Table”).
