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mysql/205510.html">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

mysql,連續簽到,簽到
