Re: GUID/UUID Performance

In the code example isn't there a separator between the create statement of the functions missing ? ()

 DELIMITER //

    CREATE FUNCTION UuidToBin(_uuid BINARY(36))
        RETURNS BINARY(16)
        LANGUAGE SQL  DETERMINISTIC  CONTAINS SQL  SQL SECURITY INVOKER
    RETURN
        UNHEX(CONCAT(
            SUBSTR(_uuid, 15, 4),
            SUBSTR(_uuid, 10, 4),
            SUBSTR(_uuid,  1, 8),
            SUBSTR(_uuid, 20, 4),
            SUBSTR(_uuid, 25) ));
//
    CREATE FUNCTION UuidFromBin(_bin BINARY(16))
        RETURNS BINARY(36)
        LANGUAGE SQL  DETERMINISTIC  CONTAINS SQL  SQL SECURITY INVOKER
    RETURN
        LCASE(CONCAT_WS('-',
            HEX(SUBSTR(_bin,  5, 4)),
            HEX(SUBSTR(_bin,  3, 2)),
            HEX(SUBSTR(_bin,  1, 2)),
            HEX(SUBSTR(_bin,  9, 2)),
            HEX(SUBSTR(_bin, 11))
                 ));

    //
    DELIMITER ;
