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.

--ndb-connectstring
. --ndb-optimized-node-selection
Command-Line Format --ndb-optimized-node-selection

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
. -
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

Command-Line Format --print-defaults
Print program argument list and exit.
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 table2
: User-created table3
: 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.
-
Command-Line Format --usage
Display help text and exit; same as
--help
. -
Command-Line Format --version

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”).
