MySQL 8.4 Reference Manual Including MySQL NDB Cluster 8.4
ndb_delete_all deletes all rows from the
given NDB table. In some cases,
this can be much faster than
DELETE or even
TRUNCATE TABLE.
ndb_delete_all -cconnection_stringtbl_name-ddb_name
This deletes all rows from the table named
tbl_name in the database named
db_name. It is exactly equivalent to
executing TRUNCATE
in MySQL.
db_name.tbl_name

| 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.
| Command-Line Format | --print-defaults |

With very large tables, using this option may cause the number of operations available to the cluster to be exceeded.
Run a tuple scan.
| Command-Line Format | --usage |
|---|
Display help text and exit; same as
--help.
| Command-Line Format | --version |
|---|
