MySQL 8.4 Reference Manual Including MySQL NDB Cluster 8.4
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.

---|---|
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

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 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.
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”).
