SQL Server到底需要使用哪些端口

SQLServer在安装到服务器上后，由于出于服务器安全的需要，所以需要屏蔽掉所有不使用的端口，只开放必须使用的端口。下面就来介绍下SQLServer2008中使用的端口有哪些：首先，最常用最常见的就是1433端口。这个是数据库引擎的端口，如果我们要远程连接数据库引擎，那么就需要打开该端口。这个端口是可以修改的，在“SQLServer配置管理器”中切换到“XXX的协议”里面选择，TCP/IP协议属性中可以设置TCP端口。如图所示：SSIS要调用DCOM协议

Group By去除重复数据

今天在写一个sql，目的是去除表里某一个字段相同的数据，只保留最新的一条。之前groupby用的少。特此记录一下。SELECT*FROMlitb_approval_taskSELECTMAX(taskid),ApproverId,MAX([approvalid]),MAX([CreateUserID]),MAX([CreateUserName]),MAX([status]),MAX([adddate])FROMlitb_approval_taskGROUP

Samba 3.5.10 发布

Samba现在有三个活动分支，分别是4.0、3.6.x和3.5.x，今天发布的3.5.10是一个bugfix版本而已。Samba，是种自由软件，用来让UNIX系列的操作系统与微软Windows操作系统的SMB/CIFS（ServerMessageBlock/CommonInternetFileSystem）网络协定做连结。在目前的版本（v3），不仅可存取及分享SMB的资料夹及打印机，本身还可以整合入WindowsServer的网域、扮演为网域控制站（Dom

凸包计算模块ConvexHull的使用方法

开发了一个模块，可用来计算平面一些点所构成的凸包。模块名为ConvexHull.dll。使用方法是这样的，新建一个WinForm工程（控制台工程也行，只是输出结果不大直观），引用ConvexHull.dll，然后在Form1代码中引用模块的命名空间：
