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

This statement is a MySQL extension. It returns characteristics of a stored procedure, such as the database, name, type, creator, creation and modification dates, and character set information. A similar statement, SHOW FUNCTION STATUS, displays information about stored functions (see Section 13.7.7.20, “SHOW FUNCTION STATUS Statement”).

To use either statement, you must be the user named as the routine DEFINER, have the SHOW_ROUTINE privilege, have the SELECT privilege at the global level, or have the CREATE ROUTINE, ALTER ROUTINE, or EXECUTE privilege granted at a scope that includes the routine.

The LIKE clause, if present, indicates which procedure or function names to match. The WHERE clause can be given to select rows using more general conditions, as discussed in Section 26.8, “Extensions to SHOW Statements”.

character_set_client: utf8mb4
collation_connection: utf8mb4_0900_ai_ci
  Database Collation: utf8mb4_0900_ai_ci

character_set_client is the session value of the character_set_client system variable when the routine was created. collation_connection is the session value of the collation_connection system variable when the routine was created. Database Collation is the collation of the database with which the routine is associated.

Stored routine information is also available from the INFORMATION_SCHEMA PARAMETERS and ROUTINES tables. See Section 26.3.20, “The INFORMATION_SCHEMA PARAMETERS Table”, and Section 26.3.30, “The INFORMATION_SCHEMA ROUTINES Table”.
