13.7.4.6 UNINSTALL PLUGIN Syntax
- UNINSTALL PLUGIN plugin_name
This statement removes an installed server plugin. It requires
the DELETE privilege for the
mysql.plugin system table.
UNINSTALL PLUGIN is the
complement of INSTALL PLUGIN.
plugin_name must be the name of some
plugin that is listed in the mysql.plugin
table. The server executes the plugin's deinitialization
function and removes the row for the plugin from the
mysql.plugin system table, so that subsequent
server restarts will 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 a FULLTEXT 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 with mysqldump and remove the
WITH PARSER clause from the dumped
CREATE 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.
For additional information about plugin loading, see Section 5.6.1, “Installing and Uninstalling Plugins”.
