21.15 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, 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 Section 5.5.1, “Installing and Uninstalling Plugins”.

Notes

• The PLUGINS table 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 Section 24.2, “The MySQL Plugin API”.

Plugin information is also available from the SHOW PLUGINS statement. See Section 13.7.5.26, “SHOW PLUGINS Statement”. These statements are equivalent:

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

SHOW PLUGINS;
