WEEK3|WEB(5/6)medium_sqlSqlmap一把梭（部分能直接flag'部分出现flag不完整或者部分爆不到表等官方wp）在week1的基础上，多过滤了union。验证存在布尔盲注：?id=TMP0919'Andif(1>0,1,0)#?id=TMP0919'Andif(0>1,1,0)#发第一个，有回显，第二个，没回显，说明页面可以根据if判断的结果回显两种（真假）内容，因此是布尔盲注。盲注脚本，用二分查找。（不会二分查找也没事，可以尝试自己写，反正初学别用sqlmap）importrequestsdefcondition(res):if'Physics'inres.text
我目前有一个数据库来跟踪销售团队的销售情况。我有一个查询将提取每个销售员及其相关的总数，但我希望按周对此进行分割，然后如果可能的话在一周内汇总显示。我当前使用的查询是:SELECTROUND(SUM(n.newBalance),2)ASnewB,u.usernameFROM(SELECTj.leadidAScustid,WEEK(j.convertdate)ASweeks,j.price/(SELECTcount(*)FROMassignmentstblaWHEREa.custid=j.leadid)ASnewBalanceFROMjobbooktbljWHEREj.convertda

和标题差不多我基本上想做一个简单的查询...SELECT*FROMsign_in_outWHEREuser_id=6ANDtime_signed...获取指定日期之前最近的登录/注销事件，以确定相关用户在该天开始时是登录还是注销。上面的查询工作正常，但问题是我没有那样的日期，我有YEAR、WEEK和WEEKDAY。如何在MySQL中根据这些创建DATE？谢谢 最佳答案 SELECT*FROMsign_in_outWHEREuser_id=6ANDtime_signed检查手册MAKEDATE

最近没什么正式比赛，都是入门赛，有moectf,newstar,SHCTF,0xGame都是漫长的比赛。一周一堆制。这周newstar第1周结束了，据说py得很厉害，第2周延期了，什么时候开始还不一定，不过第一周已经结束提交了，可以发上来存下。总体来说没难题。 Cryptobrainfuck++++++++[>>++>++++>++++++>++++++++>++++++++++>++++++++++++>++++++++++++++>++++++++++++++++>++++++++++++++++++>++++++++++++++++++++>++++++++++++++++++++++>
