15.7.4.5 UNINSTALL COMPONENT Statement

UNINSTALL COMPONENT component_name [, component_name ] ...

This statement deactivates and uninstalls one or more components. A component provides services that are available to the server and other components; seeSection 7.5, “MySQL Components”. UNINSTALL COMPONENT is the complement ofINSTALL COMPONENT. It requires the DELETE privilege for themysql.component system table because it removes the row from that table that registers the component.UNINSTALL COMPONENT does not undo persisted variables, including the variables persisted usingINSTALL COMPONENT ... SET PERSIST.

Example:

UNINSTALL COMPONENT 'file://component1', 'file://component2';

For information about component naming, seeSection 15.7.4.3, “INSTALL COMPONENT Statement”.

If any error occurs, the statement fails and has no effect. For example, this happens if a component name is erroneous, a named component is not installed, or cannot be uninstalled because other installed components depend on it.

A loader service handles component unloading, which includes removing uninstalled components from themysql.component system table that serves as a registry. As a result, unloaded components are not loaded during the startup sequence for subsequent server restarts.
