因为对SQL操作比较多，但有些操作其实都是重复性的，只是参数不太一样了，例如silo id, server name 等。希望可以通过powershell脚本提高效率。
尝试如下
1. 使用PowerShell 连接数据库，本地尝试，来至：http://www.pstips.net/getting-sql-server-connection-string.html.
当你用Powershell获取SQL连接字符串，你会需要“连接字符串”，这段字符串要包涵连接数据库实例的多个片段。
传统方法构建一个这样的字符串也不容易，下面有段函数也许可以帮助您完成：

#requires -Version 2function Get-ConnectionString{ $Path = Join-Path -Path $env:TEMP -ChildPath 'dummy.udl' $null = New-Item -Path $Path -ItemType File -Force $CommandArg = """$env:CommonProgramFilesSystemOLE DBoledb32.dll"",OpenDSLFile " + $Path Start-Process -FilePath Rundll32.exe -ArgumentList $CommandArg -Wait $ConnectionString = Get-Content -Path $Path | Select-Object -Last 1 $ConnectionString | clip.exe Write-Warning -Message 'Connection String is also available from clipboard' $ConnectionString} |
当你运行Get-ConnectionString，Powershell会弹出一个对话框，你可以提交一个测试连接，接着关闭窗口，Powershell将返回一个一个连接字符串。
使用如下配置连接成功。
2. Powershell 连接SQL数据库，来至：http://www.pstips.net/accessing-an-sql-database-with-a-connection-string.html
先前的技巧中我们学习了如何创建一个SQL连接字符串，当你有了一个连接字符串并且它是有效的，接下来的例子就是演示如何向数据库提交一个SQL命令：
