SHOW PLUGINS returns the following columns:

  • Name is the name used to refer to the plugin in statements such as INSTALL PLUGIN and UNINSTALL PLUGIN.

  • Status indicates the plugin status, one of ACTIVE, INACTIVE, DISABLED, or DELETED.

  • Type indicates the type of plugin, such as STORAGE ENGINE or INFORMATION_SCHEMA.

  • 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.

  • Licensed indicates how the plugin is licensed; for example, GPL.

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

For information about plugin data structures that form the basis of the information displayed by SHOW PLUGINS, see Section 21.2, “The MySQL Plugin API”.

Plugin information is also available in the INFORMATION_SCHEMA.PLUGINS table. See Section 19.17, “The INFORMATION_SCHEMA PLUGINS Table”.
