PowerShell 连接SQL

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 2

function Get-ConnectionString

{

$Path = Join-Path -Path $env:TEMP -ChildPath 'dummy.udl'

$null = New-Item -Path $Path -ItemType File -Force

$CommandArg = """$env:CommonProgramFiles\System\OLE DB\oledb32.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：

#requires -Version 2

# make sure this is a valid connection string to your database

# see www.connectionstrings.com for reference

$connectionString = 'Provider=SQLOLEDB.1;Password=.topSecret!;Persist Security

Info=True;User ID=sa;Initial Catalog=test;Data Source=myDBServer\SQLEXPRESS2012'

# make sure this is valid SQL for your database

# so in this case, make sure there is a table called "test"

$sql = 'select * from test'

$db = New-Object -ComObject ADODB.Connection

$db.Open($connectionString)

$rs = $db.Execute($sql)

$results = While ($rs.EOF -eq $false)

{

$CustomObject = New-Object -TypeName PSObject

$rs.Fields | ForEach-Object -Process {

$CustomObject | Add-Member -MemberType NoteProperty -Name $_.Name -Value $_.Value

}

$CustomObject

$rs.MoveNext()

}

$results | Out-GridView
