SHOW FUNCTION STATUS

Syntax

SHOW FUNCTION STATUS
    [LIKE 'pattern' | WHERE expr]

Description

This statement is similar to SHOW PROCEDURE STATUS but for stored functions.

The LIKE clause, if present on its own, indicates which function names to match.

The WHERE and LIKE clauses can be given to select rows using more general conditions, as discussed in Extended SHOW.

The information_schema.ROUTINES table contains more detailed information.

Examples
