对于我的工作,我经常需要从 Microsoft SQL 2008 服务器编写包含所有键、约束和触发器的表(基本上是重新创建表的完整脚本)。我还必须为过程和触发器执行此操作。我现在要做的是打开 SSMS 右键单击​​对象并选择脚本并选择将其脚本写入文件。因此,如果我有 3 个程序要做、10 个表和 1 个触发器,我最终会这样做 14 次。我想要的是一个powershell脚本,我可以将一个对象列表提供给它,然后它会使用SMO将每个脚本写入一个单独的文件。

谢谢您的帮助

这是我在必须编写数据库脚本时使用的 PowerShell 函数。它应该很容易修改,只为您需要的对象编写脚本。

function SQL-Script-Database
{
    <#
    .SYNOPSIS
    Script all database objects for the given database.

    .DESCRIPTION
    This  function scripts all database objects  (i.e.: tables,  views, stored
    procedures,  and user defined functions) for the specified database on the
    the given server\instance. It creates a subdirectory per object type under 
    the path specified.

    .PARAMETER savePath
    The root path where to save object definitions.

    .PARAMETER database
    The database to script (default = $global:DatabaseName)

    .PARAMETER DatabaseServer 
    The database server to be used (default: $global:DatabaseServer).

    .PARAMETER InstanceName 
    The instance name to be used (default: $global:InstanceName).

    .EXAMPLE
    SQL-Script-Database c:\temp AOIDB
    #>

    param (
        [parameter(Mandatory = $true)][string] $savePath,
        [parameter(Mandatory = $false)][string] $database = $global:DatabaseName,
        [parameter(Mandatory = $false)][string] $DatabaseServer = $global:DatabaseServer,
        [parameter(Mandatory = $false)][string] $InstanceName = $global:InstanceName
    )

    try
    {
        if (!$DatabaseServer -or !$InstanceName)
            { throw "`$DatabaseServer or `$InstanceName variable is not properly initialized" }

        $ServerInstance = SQL-Get-Server-Instance $DatabaseServer $InstanceName

        [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null

        $s = New-Object Microsoft.SqlServer.Management.Smo.Server($ServerInstance)
        $db = $s.databases[$database]

        $objects = $db.Tables
        $objects += $db.Views
        $objects += $db.StoredProcedures
        $objects += $db.UserDefinedFunctions

        $scripter = New-Object ('Microsoft.SqlServer.Management.Smo.Scripter') ($s)

        $scripter.Options.AnsiFile = $true
        $scripter.Options.IncludeHeaders = $false

        $scripter.Options.ScriptBatchTerminator = $false

        $scripter.Options.Indexes = $true
        $scripter.Options.ClusteredIndexes = $true
        $scripter.Options.NonClusteredIndexes = $true
        $scripter.Options.NoCollation = $true

        $scripter.Options.DriAll = $true
        $scripter.Options.DriIncludeSystemNames = $false

        $scripter.Options.ToFileOnly = $true
        $scripter.Options.Permissions = $true

        foreach ($o in $objects | where {!($_.IsSystemObject)}) 
        {
            $typeFolder=$o.GetType().Name 

            if (!(Test-Path -Path "$savepath\$typeFolder")) 
                { New-Item -Type Directory -name "$typeFolder"-path "$savePath" | Out-Null }

            $file = $o -replace "\[|\]"
            $file = $file.Replace("dbo.", "")

            $scripter.Options.FileName = "$savePath\$typeFolder\$file.sql"
            $scripter.Script($o)
        }
    }

    catch
    {
        Util-Log-Error "`t`t$($MyInvocation.InvocationName): $_"
    }
}

这是一个备份单个对象的脚本。只需将对象名称传递给函数:
