MySql 存储过程游标使用示例

DROP PROCEDURE IF exists pro_removeBillRemindByUserId;
create procedure pro_removeBillRemindByUserId(userId int)
begin
    declare ts varchar(500);
    declare cnt int default 0;
    declare f_ID,b  int;
    DECLARE cur_1 CURSOR FOR select  FID from t_bill  where FUserId=userId;
DECLARE CONTINUE HANDLER FOR NOT FOUND
SET b = 1;
OPEN cur_1;
REPEAT
FETCH cur_1 INTO f_ID;
    delete from t_bill_remind where FBillID=f_ID;
UNTIL b = 1
END REPEAT;
    close cur_1;
end;
//调用存储过程
call pro_removeBillRemindByUserId(678);
