MySQL 9.0 Reference Manual  / ...  / MySQL Server Administration  / MySQL Server Loadable Functions  /  Obtaining Information About Loadable Functions

7.7.2 Obtaining Information About Loadable Functions

The Performance Schemauser_defined_functions table contains information about the currently installed loadable functions:

SELECT * FROM performance_schema.user_defined_functions;

Themysql.func system table also lists installed loadable functions, but only those installed usingCREATE FUNCTION. Theuser_defined_functions table lists loadable functions installed usingCREATE FUNCTION as well as loadable functions installed automatically by components or plugins. This difference makesuser_defined_functions preferable tomysql.func for checking which loadable functions are installed. SeeSection 29.12.22.10, “The user_defined_functions Table”.
