最近写的一个MySQL存储过程 [复制链接]

前一阵子做一个统计功能,于是写了个存储过程,就是根据一定的算法,用基础数据来计算另一个表的数据.

下面是几个存储过程,从生成原始数据到计算结果,我在MySQL 5.0.18版本上运行通过,我就不贴表结构了,主要是让大家看看语法.贴这儿也是自己以后再写时可以参考.

------------------------- 自动生成随机数据存储过程 -------------------------
drop PROCEDURE if exists genRand;
delimiter //
create PROCEDURE genRand(in rank int, in add_num int, in statTime char(10))
-- rank:随机最大邮件数, add_num:生成条数, startTime:统计数据日期
Begin
    declare mobile long;
    declare tmp int;
    set mobile = 13600000000;
    set tmp = 1;
    -- delete from ippush_stats_email;
    while tmp <= add_num do
        insert into ippush_stats_email values(mobile + tmp, 1, now(), statTime,
                                                  random_int(rank), random_int(rank), random_int(rank), random_int(rank), random_int(rank),
                                                  random_int(rank), random_int(rank), random_int(rank), random_int(rank), random_int(rank),
                                                  random_int(rank), random_int(rank), random_int(rank), random_int(rank), random_int(rank),
                                                  random_int(rank), random_int(rank), random_int(rank), random_int(rank), random_int(rank),
                                                  random_int(rank), random_int(rank), random_int(rank), random_int(rank) );
        set tmp = tmp + 1;
    end while;
end//
delimiter ;
call genRand(10, 10, '2010-10-6');

------------------------- 统计从time1到time2时段的 -------------------------

                                    clock_10+clock_11+clock_12+clock_13+clock_14+clock_15+clock_16+clock_17+clock_18+clock_19+
                                    clock_20+clock_21+clock_22+clock_23+clock_24)) as sums
                                from ippush_stats_email
                                where stat_time >= time1 and stat_time <= time2
                                group by mobile;
    declare CONTINUE HANDLER FOR NOT FOUND SET fetchSeqOk = 0;

    set fetchSeqOk = 1;
    open fetchSeqCursor;
    while fetchSeqOk = 1 do
            fetch fetchSeqCursor into _mobile, _count, _user_type, _stat_time, _sums;
            if _sums > 30 then
                call onelineStat(1, _user_type, time1, time2, _mobile);
            else
                call onelineStat(2, _user_type, time1, time2, _mobile);
            end if;
    end while;
    close fetchSeqCursor;
end//
