How can we view the list of stored functions in a specific MySQL database with complete information?

We can view the list of stored functions in a specific MySQL database with complete information in mysql.proc with the following query -

mysql> Select * from mysql.proc where db = 'query' AND type = 'FUNCTION' \G
*************************** 1. row ***************************
                  db: query
                name: factorial
                type: FUNCTION
       specific_name: factorial
            language: SQL
     sql_data_access: CONTAINS_SQL
    is_deterministic: YES
       security_type: DEFINER
          param_list: n DECIMAL(3,0)
             returns: decimal(20,0)
                body: BEGIN
DECLARE factorial DECIMAL(20,0) DEFAULT 1;
DECLARE counter DECIMAL(3,0);
SET counter = n;
      factorial_loop: REPEAT
SET factorial = factorial * counter;
SET counter = counter - 1;
UNTIL counter = 1
END REPEAT;
RETURN factorial;
END
