存儲過程developer_count 是根據傳入參數searchType 決定是使用那種查詢方式，本存儲過程中包含的其他的參數是{起始時間：startime,結束時間：endtime}

1. CREATE PROCEDURE developer_count
2. (
3. searchType int,
4. startTime varchar(64),
5. endTime varchar(64)
6. )
7. BEGIN
8. /*定義變量天數*/
9. declare day_num int;
11. if searchType = 1 then
12. /*本周數據查詢*/
13. select count(d.acct_id),d.acct_old_time from developer d where 1=1 and DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
14. end if;
15. if searchType = 2 then
16. /*本月數據查詢*/
17. select count(d.acct_id),d.acct_old_time from developer d where 1=1 and DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
18. end if;
19. if searchType = 3 then
20. /*最近三個月數據查詢*/
21. select count(d.acct_id), DATE_FORMAT(d.acct_old_time,‘%x年-第%v周‘) as weeks from developer d where 1=1 and DATE_SUB(CURDATE(), INTERVAL 90 DAY) <= date(d.acct_old_time) GROUP BY weeks;
22. end if;
23. if searchType = 4 then
24. /*按月份進行數據統計*/
25. select datediff(startTime, endTime) into day_num;
26. if day_num <=7 then
27. select count(d.acct_id),d.acct_old_time from developer d where 1=1 and DATE_SUB(CURDATE(), INTERVAL day_num DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
28. end if;
29. if day_num >7 && day_num <= 30 then
30. select count(d.acct_id),d.acct_old_time from developer d where 1=1 and DATE_SUB(CURDATE(), INTERVAL day_num DAY) <= date(d.acct_old_time) GROUP BY d.acct_old_time;
31. end if;
32. if day_num >30 && day_num <= 90 then
33. select count(d.acct_id), DATE_FORMAT(d.acct_old_time,‘%x年-第%v周‘) as weeks from developer d where 1=1 and DATE_SUB(CURDATE(), INTERVAL day_num DAY) <= date(d.acct_old_time) GROUP BY weeks;
34. end if;
35. end if;
37. end;

CALL DEVELOPER_COUNT(1,‘2016-06-07‘,‘2016-06-16‘);調用存儲過程
