--character-sets-dir

包含字符集的目录。Directory containing character sets.

--connect-retries

放弃之前重试连接的次数。Number of times to retry connection before giving up.

--connect-retry-delay

--connect-string

与 --ndb-connectstring 相同。Same as --ndb-connectstring.

--core-file

错误时生成核心文件；用于调试。Write core file on error; used in debugging.

--database, -d

指定所需表所在的数据库名称。如果提供此选项，则表名必须跟在数据库名称之后。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.

如果未指定此选项，并且在 TEST_DB 数据库中未找到任何表，ndb_show_tables 将发出警告。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

在读取全局文件之后读取给定文件。Read given file after global files are read.

--defaults-file

仅从指定文件读取默认选项。Read default options from given file only.

--defaults-group-suffix

也读取组合了 concat(group, suffix) 的组。Also read groups with concat(group, suffix).

--help

显示帮助文本并退出。Display help text and exit.

--login-path

从登录文件读取给定路径。Read given path from login file.

--no-login-paths

跳过从登录路径文件读取选项。Skips reading options from the login path file.

--loops, -l

指定实用程序应执行的次数。当未指定此选项时，默认为 1，但如果使用此选项，则必须提供一个整数参数。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

设置用于连接到 ndb_mgmd 的连接字符串。语法：[nodeid=id;][host=]hostname[:port]。覆盖 NDB_CONNECTSTRING 和 my.cnf 中的条目。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

设置连接到管理服务器所需的 TLS 支持级别；可以是 relaxed 或 strict。relaxed（默认）表示尝试建立 TLS 连接，但不要求成功；strict表示连接必须使用 TLS。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

与 --ndb-connectstring 相同。Same as --ndb-connectstring.

--ndb-nodeid

设置此节点的节点 ID，覆盖任何由 --ndb-connectstring 设置的 ID。Set node ID for this node, overriding any ID set by --ndb-connectstring.

--ndb-optimized-node-selection

启用事务节点选择的优化。默认启用；使用 --skip-ndb-optimized-node-selection 来禁用。Enable optimizations for selection of nodes for transactions. Enabled by default; use --skip-ndb-optimized-node-selection to disable.

--ndb-tls-search-path

指定用于搜索 CA 文件的目录列表。在 Unix 平台上，目录名称用冒号 (:) 分隔；在 Windows 系统上，使用分号 (;) 作为分隔符。目录引用可以是相对路径或绝对路径；它可以包含一个或多个环境变量，每个变量以美元符号 ($) 开头，并在使用前进行展开。Specify a list of directories to search for a CA file. On Unix platforms, the directory names are separated by colons (:); on Windows systems, the semicolon character (;) is used as the separator. A directory reference may be relative or absolute; it may contain one or more environment variables, each denoted by a prefixed dollar sign ($), and expanded prior to use.

搜索从最左边的命名目录开始，按从左到右的顺序进行，直到找到文件。空字符串表示空搜索路径，这会导致所有搜索失败。由单个点 (.) 组成的字符串表示搜索路径仅限于当前工作目录。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.

如果未提供搜索路径，则使用编译时的默认值。此值取决于所使用的平台：在 Windows 上，它是 \ndb-tls；在其他平台（包括 Linux）上，它是 $HOME/ndb-tls。可以通过使用 -DWITH_NDB_TLS_SEARCH_PATH 编译 NDB Cluster 来覆盖该值。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

除了登录文件之外，不从任何配置文件读取默认选项。Do not read default options from any option file other than login file.

--parsable, -p

使用此选项会使输出格式适用于LOAD DATA。Using this option causes the output to be in a format suitable for use with LOAD DATA.

--print-defaults

打印程序参数列表然后退出。Print program argument list and exit.

--show-temp-status

如果指定，将显示临时表。If specified, this causes temporary tables to be displayed.

--type, -t

可以用于将输出限制为一种类型的对象，通过整数类型代码指定，如下所示：Can be used to restrict the output to one type of object, specified by an integer type code as shown here:

任何其他值将导致列出所有 NDB 数据库对象（默认值）。Any other value causes all NDB database objects to be listed (the default).

--unqualified, -u

如果指定，则显示未限定的对象名称。If specified, this causes unqualified object names to be displayed.

--usage

显示帮助文本并退出；与--help相同。Display help text and exit; same as --help.

--version

显示版本信息并退出。Display version information and exit.
