20.17. The `INFORMATION_SCHEMA PLUGINS` Table

The PLUGINS table provides information about server plugins.

Notes:

The PLUGINS table is a nonstandard table.
PLUGIN_NAME is the name used to refer to the plugin in statements such as INSTALL PLUGIN and UNINSTALL PLUGIN.
PLUGIN_VERSION is the version from the plugin's general type descriptor.
PLUGIN_STATUS indicates the plugin status, one of ACTIVE, INACTIVE, DISABLED, or DELETED.
PLUGIN_TYPE indicates the type of plugin, such as STORAGE ENGINE or INFORMATION_SCHEMA.
PLUGIN_TYPE_VERSION is the version from the plugin's type-specific descriptor.
PLUGIN_LIBRARY is the name of the plugin shared object 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 indicates the plugin API interface version.
PLUGIN_AUTHOR names the plugin author.
PLUGIN_DESCRIPTION provides a short description of the plugin.
PLUGIN_LICENSE indicates how the plugin is licensed; for example, GPL.

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

These statements are equivalent:

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

SHOW PLUGINS;

For information about plugin data structures that form the basis of the information in the PLUGINS table, see Section 23.2, “The MySQL Plugin API”.

Plugin information is also available using the SHOW PLUGINS statement. See Section 12.4.5.26, “SHOW PLUGINS Syntax”.
