16. PLUGINS

PLUGINS表提供有关服务器插件的信息。

PLUGINS表有以下列：

PLUGIN_NAME ：用于在诸如INSTALL PLUGIN和UNINSTALL PLUGIN之类的语句中引用插件的名称。
PLUGIN_VERSION ：插件的常规类型描述符中的版本。
PLUGIN_STATUS ：插件状态，ACTIVE，INACTIVE，DISABLED或DELETED之一。
PLUGIN_TYPE ：插件的类型，例如STORAGE ENGINE，INFORMATION_SCHEMA或AUTHENTICATION。
PLUGIN_TYPE_VERSION ：插件的特定于类型的描述符中的版本。
PLUGIN_LIBRARY ：插件共享库文件的名称。这是用于在诸如INSTALL PLUGIN和UNINSTALL PLUGIN之类的语句中引用插件文件的名称。该文件位于plugin_dir系统变量指定的目录中。如果库名称为NULL，则插件将被编译，并且无法使用UNINSTALL PLUGIN进行卸载。
PLUGIN_LIBRARY_VERSION：插件API接口版本。
PLUGIN_AUTHOR ：插件作者
PLUGIN_DESCRIPTION ：插件的简短描述。
PLUGIN_LICENSE ：插件如何获得许可; 例如，GPL。
LOAD_OPTION ：如何加载插件。值为OFF，ON，FORCE或FORCE_PLUS_PERMANENT。请参考“安装和卸载插件”。

Notes

PLUGINS表是一个非标准的INFORMATION_SCHEMA表。
对于使用INSTALL PLUGIN安装的插件，PLUGIN_NAME和PLUGIN_LIBRARY值也会在mysql.plugin表中注册。
有关构成PLUGINS表中信息基础的插件数据结构的信息，请参见“MySQL插件API”。
插件信息也可以从SHOW PLUGINS语句中获得。请参见“SHOW PLUGINS语法”。
