MySQL Information Schema  /  INFORMATION_SCHEMA General Tables  /  The INFORMATION_SCHEMA PLUGINS Table

4.22 The INFORMATION_SCHEMA PLUGINS Table

The PLUGINS table provides information about server plugins.

The PLUGINS table has these columns:

  • PLUGIN_NAME

    The name used to refer to the plugin in statements such as INSTALL PLUGIN and UNINSTALL PLUGIN.

  • PLUGIN_VERSION

    The version from the plugin's general type descriptor.

  • PLUGIN_STATUS

    The plugin status, one of ACTIVE, INACTIVE, DISABLED, DELETING, or DELETED.

  • PLUGIN_TYPE

    The type of plugin, such as STORAGE ENGINE, INFORMATION_SCHEMA, or AUTHENTICATION.

  • PLUGIN_TYPE_VERSION

    The version from the plugin's type-specific descriptor.

  • PLUGIN_LIBRARY

    The name of the plugin shared library file. This is the name used to refer to the plugin file in statements such as INSTALL PLUGIN and UNINSTALL PLUGIN. This file is located in the directory named by the plugin_dir system variable. If the library name is NULL, the plugin is compiled in and cannot be uninstalled with UNINSTALL PLUGIN.

  • PLUGIN_LIBRARY_VERSION

    The plugin API interface version.

  • PLUGIN_AUTHOR

    The plugin author.

  • PLUGIN_DESCRIPTION

    A short description of the plugin.

  • PLUGIN_LICENSE

    How the plugin is licensed (for example, GPL).

  • LOAD_OPTION

    How the plugin was loaded. The value is OFF, ON, FORCE, or FORCE_PLUS_PERMANENT. See Installing and Uninstalling Plugins.

Notes

  • PLUGINS is a nonstandard INFORMATION_SCHEMA table.

  • For plugins installed with INSTALL PLUGIN, the PLUGIN_NAME and PLUGIN_LIBRARY values are also registered in the mysql.plugin table.

  • For information about plugin data structures that form the basis of the information in the PLUGINS table, see The MySQL Plugin API.

Plugin information is also available from the SHOW PLUGINS statement. See SHOW PLUGINS Statement. These statements are equivalent:

SELECT
  PLUGIN_NAME, PLUGIN_STATUS, PLUGIN_TYPE,
  PLUGIN_LIBRARY, PLUGIN_LICENSE
FROM INFORMATION_SCHEMA.PLUGINS;
SHOW PLUGINS;
