13.7.4.5 UNINSTALL COMPONENT Syntax

UNINSTALL COMPONENT component_name [, component_name ] ...

This statement deactivates and uninstalls one or more server components. A component provides services that are available to the server and other components; see Section 5.5, “MySQL Server Components”. UNINSTALL COMPONENT is the complement of INSTALL COMPONENT. It requires the DELETE privilege for the mysql.component system table.

Example:

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

For information about component naming, see Section 13.7.4.3, “INSTALL COMPONENT Syntax”.

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 the mysql.component system table that serves as a registry. As a result, unloaded components are not loaded during the startup sequence for subsequent server restarts.
