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
