這篇文章主要介紹了MYSQL實現連續簽到功能斷簽一天從頭開始,非常不錯,具有參考借鑒價值,需要的朋友可以參考下1,創建測試表
CREATE TABLE `testsign` ( `userid` int(5) DEFAULT NULL, `username` varchar(20) DEFAULT NULL, `signtime` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `type` int(1) DEFAULT '0' COMMENT '為0表示簽到數據,1表示簽到日期字典數據' ) ENGINE=InnoDB DEFAULT CHARSET=utf8
2,插入測試數據,簽到時間為5.21號到6.5號,可以寫活,但是要寫存儲過程,我比較懶,重點應該是取簽到數據的代碼,就是第三點,呵呵
insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-21 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-22 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-23 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-24 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-25 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-26 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-27 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-28 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-29 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-30 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-05-31 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-06-01 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-06-02 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-06-03 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-06-04 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('72164','字典','2017-06-05 00:00:00','1'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('800675','吳小雙簽到數據','2017-05-21 00:00:00','0'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('800675','吳小雙簽到數據','2017-05-22 00:00:00','0'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('800675','吳小雙簽到數據','2017-05-23 00:00:00','0'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('800675','吳小雙簽到數據','2017-05-24 00:00:00','0'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('800675','吳小雙簽到數據','2017-05-25 00:00:00','0'); insert into `testsign` (`userid`, `username`, `signtime`, `type`) values('800675','吳小雙簽到數據','2017-05-26 00:00:00','0');
3,查詢連續簽到數據
SELECT * FROM testsign WHERE TYPE=0 AND DATE_FORMAT(signtime,'%Y%m%d')>( SELECT IFNULL(MAX(DATE_FORMAT(signtime,'%Y%m%d')),"20170520") FROM testsign WHERE TYPE=1 AND DATE_FORMAT(signtime,'%Y%m%d')<=DATE_ADD(NOW(), INTERVAL -1 DAY) AND DATE_FORMAT(signtime,'%Y%m%d') NOT IN ( SELECT DATE_FORMAT(signtime,'%Y%m%d') FROM testsign WHERE TYPE=0 AND userid=800675 ) ) AND DATE_FORMAT(signtime,'%Y%m%d')<='20170605' AND userid=800675
未斷數據
刪掉23號數據,從24號開始算,連續簽三天
