使用 Powershell 更改 SSRS 报表的数据源

Question

我正在尝试将使用 Powershell 的多个 SSRS 报告的数据源更改为我的报告服务器上的一个共享数据源。这是我的代码：

cls;  
$reportserver = "myServer";<br/>
$url = "http://$($reportserver)/reportserver/reportservice2005.asmx?WSDL";";<br/>
$ssrs = New-WebServiceProxy -uri $url -UseDefaultCredential -Namespace "ReportingWebService";

[ReportingWebService.DataSource[]] $myDataSource = new-object ReportingWebService.DataSource
$myDataSource[0].Name = "myDS"";<br/>
$myDataSource[0].Item = New-Object ReportingWebService.DataSourceReference<br/>
$myDataSource[0].Item.Reference = "/Data Sources/MyDS"<br/>

$reports = $ssrs.ListChildren('/DH', $false)

$reports | ForEach-Object {<br/>
$reportPath = $_.path<br/>
 Write-Host "Report: " $reportPath<br/>
 $dataSources = $ssrs.GetItemDataSources($reportPath)<br/>
 $dataSources | ForEach-Object {<br/>
              Write-Host "Old source: $($_.Name), $($_.Item.ConnectString)"<br/>
              $ssrs.SetItemDataSources($reportPath, $myDataSource)<br/>
              Write-Host "New source: $($_.Name), $($_.Item.ConnectString)"<br/>
          }<br/>

 Write-Host "------------------------"
}

但调用“SetItemDataSources”方法时出现以下错误：

***Argument "1" having the value "ReportingWebService.DataSource[]" of "SetItemDataSources" can not be converted to type "ReportingWebService.DataSource[]".***

问题是：怎么了？类型相同！

我已将此信息打包成两个不错的脚本：

感谢 e82.eric！

你让我找到了可行的解决方案。这里是：

cls;

#Set variables:
$reportserver = "myServer";
$newDataSourcePath = "/Data Sources/MyDS"
$newDataSourceName = "MyDS";
$reportFolderPath = "/DH"
#------------------------------------------------------------------------

$ssrs = New-WebServiceProxy -uri $url -UseDefaultCredential

$reports = $ssrs.ListChildren($reportFolderPath, $false)

$reports | ForEach-Object {
            $reportPath = $_.path
            Write-Host "Report: " $reportPath
            $dataSources = $ssrs.GetItemDataSources($reportPath)
            $dataSources | ForEach-Object {
                            $proxyNamespace = $_.GetType().Namespace
                            $myDataSource = New-Object ("$proxyNamespace.DataSource")
                            $myDataSource.Name = $newDataSourceName
                            $myDataSource.Item = New-Object ("$proxyNamespace.DataSourceReference")
                            $myDataSource.Item.Reference = $newDataSourcePath

                            $_.item = $myDataSource.Item

                            $ssrs.SetItemDataSources($reportPath, $_)

                            Write-Host "Report's DataSource Reference ($($_.Name)): $($_.Item.Reference)"
                            }

            Write-Host "------------------------" 
            }

我遇到了同样的问题。

这不是一个很好的解决方案，但根据http://www.vistax64.com/powershell/273120-bug-when-using-namespace-parameter-new-webserviceproxy.html。 New-WebServiceProxy 的命名空间参数有些损坏。该帖子建议使用最终为我工作的自动生成的名称空间，所以我认为您可以这样做。

$reportserver = "myServer"
$url = "http://$($reportserver)/reportserver/reportservice2005.asmx?WSDL"
$ssrs = New-WebServiceProxy -uri $url -UseDefaultCredential

$proxyNamespace = $ssrs.GetType().Namespace

$myDataSource = New-Object ("$proxyNamespace.DataSource") 
$myDataSource[0].Name = "myDS"
$myDataSource[0].Item = New-Object ("$proxyNamespace.DataSourceReference")
$myDataSource[0].Item.Reference = "/Data Sources/MyDS"

$reports = $ssrs.ListChildren('/DH', $false)

$reports | ForEach-Object {
$reportPath = $.path
Write-Host "Report: " $reportPath
$dataSources = $ssrs.GetItemDataSources($reportPath)
$dataSources | ForEach-Object {
Write-Host "Old source: $($.Name), $($.Item.ConnectString)"
$ssrs.SetItemDataSources($reportPath, @($myDataSource))
Write-Host "New source: $($.Name), $($_.Item.ConnectString)"
}

Write-Host "------------------------" }
