UNINSTALL PLUGINplugin_name

This statement removes an installed server plugin.UNINSTALL PLUGIN is the complement ofINSTALL PLUGIN. It requires theDELETE privilege for themysql.plugin system table because it removes the row from that table that registers the plugin.

plugin_name must be the name of some plugin that is listed in themysql.plugin table. The server executes the plugin's deinitialization function and removes the row for the plugin from themysql.plugin system table, so that subsequent server restarts do not load and initialize the plugin.UNINSTALL PLUGIN does not remove the plugin's shared library file.

You cannot uninstall a plugin if any table that uses it is open.

Plugin removal has implications for the use of associated tables. For example, if a full-text parser plugin is associated with aFULLTEXT index on the table, uninstalling the plugin makes the table unusable. Any attempt to access the table results in an error. The table cannot even be opened, so you cannot drop an index for which the plugin is used. This means that uninstalling a plugin is something to do with care unless you do not care about the table contents. If you are uninstalling a plugin with no intention of reinstalling it later and you care about the table contents, you should dump the table withmysqldump and remove theWITH PARSER clause from the dumpedCREATE TABLE statement so that you can reload the table later. If you do not care about the table,DROP TABLE can be used even if any plugins associated with the table are missing.
