DELIMITER $$

CREATE TABLE FIBON
      (NUMBER1   INTEGER NOT NULL PRIMARY KEY,
       NUMBER2   INTEGER NOT NULL);

CREATE PROCEDURE FIBONNACI_START() //创建存储过程
BEGIN
   DELETE FROM FIBON;
   INSERT INTO FIBON (NUMBER1, NUMBER2) VALUES (16, 27);
END
;
CREATE PROCEDURE FIBONNACI_GIVE //创建存储过程
   (INOUT NUMBER INTEGER)
BEGIN
   DECLARE N1, N2 INTEGER;
   SELECT NUMBER1, NUMBER2
   INTO   N1, N2
   FROM   FIBON;
   SET NUMBER = N1 + N2;
   IF NUMBER > 10000 THEN
      SET NUMBER = NUMBER - 10000;
   END IF;
   SET N1 = N2;
   SET N2 = NUMBER;
   UPDATE FIBON
   SET    NUMBER1 = N1,
          NUMBER2 = N2;
END$$

DELIMITER ;

CALL FIBONNACI_START()
;
CALL FIBONNACI_GIVE(@C)
;
SELECT @C
;
CALL FIBONNACI_GIVE(@C)
;
SELECT @C
;
CALL FIBONNACI_GIVE(@C)
;
SELECT @C;

drop table FIBON;
//删除mysql存储过程
drop PROCEDURE FIBONNACI_START;
drop PROCEDURE FIBONNACI_GIVE;
