昨天的帖子说到升级VPS把网站(cutehive.com)搞崩溃，费了九牛二虎之力把PHP解析问题、curl_init问题、见证人列表的喂价显示问题解决掉了。 (图源 ：pixabay) HP委派查询出错 不过还剩一个问题，那就是PHP连接并使用MSSQL问题。我在HP委派查询工具中，连接到HiveSQL，这样可以查询委派进来（Delegations In)的HP。 至于委派进来（Delegations

这两天再次捡起PyMSSQL，发现由于MSSQL版本升级，有些之前好用的查询语句已经无法工作了。真是应了大神表情图的那句话：“今天不学习，明天变垃圾”，再不努力学习就更不上时代发展变迁啦！

데이터베이스는 그 양이 방대하여 삭제된 영역의 복구가 쉽지 않다. Apex라는 툴을 MS-SQL에서 제공하기는 하나, 이는 서버 관리 차원에서의 도구로 디지털 포렌식에 십분 활요하기 어렵다. 데이터베이스 내에서 삭제된 레코드를 복구하는 방법은 크게 다음 네 단계로 나눌 수 있다. Table List 획득 Scheme 획득 Table의 Data Page 리스트

지인이 새로운 프로젝트를 시작하면서 Stack을 설계해주었다. Database는 Oracle로 정해진 상황에서 빠른 진행을 위해 Python을 사용하기로 하고 개발환경을 구축하였다. 하지만 갑작스럽게 Database가 MSSQL로 변경되면서 Language를 변경하게 되었는데 그나마 Linux에서 오랫동안 MSSQL과 궁합을 맞춰왔던 PHP를 선택하게 되었고

平时都是使用myssql的我，最近不得不开始学习mssql了。 在mysql下： select author, Datepart(hour, created) as hh from comments where created>='2017-08-01 0:00:00' and title like "穿越诗歌" and permlink not like 're-%' group

最近我每周都要去统计“华语好声音”和“三个一”活动的一周文章列表。所以在条件语句中，总是少不了限制时间。例如，上周统计“华语好声音”的一个条件子句就是 DATEADD(hour,7, created)>='2018-01-27 00:00:00' 因为系统时间同北京时间相差7小时，所以要用DATEADD()函数把数据库里的created字段时间后移动7小时。

我想搜索一下本年发表的和中文诗有关的文章，于是我在linqpad中使用sql语句 select * from comments where created>='2018-01-01 00：00：00' and title like '%诗%' 结果是0记录，居然没有找到，这怎么回事？于是我百度谷歌，然后我换用了以下SQL语句： select * from comments where

在mysql下，我会使用select ... from (select ... from... ... order by ) tmp group by ... 无奈呀，在mssql下，子句中不支持order by 最后，在偶像 @justyy的帮助下，学会了OVER(PARTITION BY)的用法 partition by 可以按字段或字段组合进行分区，然后还可以在每个分区中按字段或字段组合进行排序

平时都是用mysql多， 无奈steemit上还是mssql数据库更好用，只好开始研究： 平时在mysql下想要移动时间都是需要date_add()函数的。它的用法是 date_add(原时间字段或常量, interval +移动数 类型) 其中类型可以year month day hour minute second

在LINQpad下查询steemsql数据，因为英语太烂，输入表名经常出错，所以就想把所有表名查询出来，复制到evernote里，需要哪个表直接就可以复制表名。 上网查了一下，在mssql下，显示所有表名的命令如下： SELECT Name FROM DatabaseName..SysObjects Where XType='U' ORDER BY Name XType='U':表示所有用户表;
