MySQL 8.3 Reference Manual / ... / ndb_drop_table — Drop an NDB Table

25.5.11 ndb_drop_table — Drop an NDB Table

ndb_drop_table drops the specified NDB table. (If you try to use this on a table created with a storage engine other than NDB, the attempt fails with the error 723: No such table exists.) This operation is extremely fast; in some cases, it can be an order of magnitude faster than using a MySQL DROP TABLE statement on an NDB table.

Usage

ndb_drop_table -c connection_string tbl_name -d db_name

Options that can be used with ndb_drop_table 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.
