我一直有相當的時間試圖弄清楚這一點。讓我試着解釋我正在努力完成的事情，希望我能夠清楚。Powershell SQL查詢結果convertto-XML
我向MSSQL數據庫發送兩個查詢並接收它們。下面的代碼是完美的，但是我想在寫入XML文件之前操作XML的格式。我目前得到3列（serviceGroupName，numAccounts，numDevices）我想完成以下兩件事之一：
1）添加一個名爲「ReportType」的新列，並填寫「Monthly」或「Total」，具體取決於如果它是foreach循環的第一遍或第二遍（SQLQuery1是月度報告，並且SQLQuery2是自開始以來的總數）
2）創建一個新的PSObject並使其填充相應的信息，例如它接收的數據（serviceGroupName，numAccounts，numDevices）
以下是我目前的代碼。正如我所說，它確實工作，它產生了一個XML，但如果可能的話，我想在管道之前添加一些更多信息到ConvertTo-XML。
### Dates to use
$Date = (Get-Date -f MM-dd-yyyy)
$FDoTM = ((Get-Date -Day 01).AddMonths(0)).AddDays(0)
$LDo2PM = ((Get-Date -Day 01).AddMonths(-1)).AddDays(-1)
$TempDir = "C:\Temp"
$WebDir = @("\\x.x.x.x\c$\inetpub\wwwroot\Reports\Accounts","\\x.x.x.x\c$\inetpub\wwwroot\Reports\Accounts")
### Something
$OutputXML = "$Date-Monthly-AccountReport.xml"
### Connection settings, uses windows authentication
$DBServer = "OMMITED"
$databasename = "OMMITED"
$Connection = new-object system.data.sqlclient.sqlconnection #Set new object to connect to sql database
$Connection.ConnectionString ="server=$DBServer;database=$databasename;trusted_connection=True" # Connectiongstring setting for local machine database with window authentication
Write-host "Connection Information:" -foregroundcolor yellow -backgroundcolor black
$Connection #List connection information
### Connect to Database and Run Query
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand #setting object to use sql commands
$OutputHeader1 = "This Month's counts"
$SqlQuery1 = @"
SET NOCOUNT ON;
WITH AccountDeviceStats(serviceGroupName,numAccounts,numDevices)
AS
(
SELECT svg.name,COUNT(acct.serviceGroupId) as Accounts, NULL FROM bm_account acct WITH (NOLOCK)
INNER JOIN bm_servicegroup svg WITH (NOLOCK) ON svg.servicegroupId = acct.serviceGroupId
where acct.CreateStamp between '$($LDo2PM)' and '$($FDoTM)'
GROUP BY acct.serviceGroupId,svg.name
UNION ALL
SELECT svg.name, NULL, COUNT(device.serviceGroupId) as Devices FROM bm_device device WITH (NOLOCK)

GROUP BY device.serviceGroupId,svg.name
)
SELECT ad1.serviceGroupName,ad1.numAccounts,ad2.numDevices FROM AccountDeviceStats ad1
INNER JOIN AccountDeviceStats ad2 ON ad1.serviceGroupName = ad2.serviceGroupName
WHERE ad1.numAccounts IS NOT NULL AND ad2.numDevices IS NOT NULL
ORDER BY numAccounts DESC,numDevices DESC
"@
$OutputHeader2 = "Total Counts"
$SqlQuery2 = @"
SET NOCOUNT ON;

AS

)
SELECT ad1.serviceGroupName,ad1.numAccounts,ad2.numDevices FROM AccountDeviceStats ad1
INNER JOIN AccountDeviceStats ad2 ON ad1.serviceGroupName = ad2.serviceGroupName
WHERE ad1.numAccounts IS NOT NULL AND ad2.numDevices IS NOT NULL
ORDER BY numAccounts DESC,numDevices DESC
"@
$sqlQueries = @($SqlQuery1, $SqlQuery2)
$Results = @()
Foreach ($Query in $sqlQueries){
$Connection.open()
Write-host "Connection to database successful." -foregroundcolor green -backgroundcolor black
$SqlCmd.CommandText = $Query
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$SqlCmd.Connection = $Connection
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$Connection.Close()
$Results += $DataSet.Tables[0]
($Results | ConvertTo-XML -NoTypeInformation).Save("$TempDir\$OutputXML")
}
if ((Get-ChildItem $TempDir -filter "$Date-*.xml").count -gt 0){
Foreach ($file in (Get-ChildItem $TempDir -filter "$Date-*.xml" -recurse)){
Foreach ($webserver in $WebDir){
Copy-Item $file.fullname "$webserver\$file" -force
}
Remove-Item $file.fullname -force
}
}
這裏是XML
<?xml version="1.0"?>
<Objects>
<Object>
<Property Name="serviceGroupName">ServiceGroup1</Property>
<Property Name="numAccounts">15</Property>
<Property Name="numDevices">28</Property>
<Property Name="RowError" />
<Property Name="RowState">Unchanged</Property>
<Property Name="Table">
<Property>System.Data.DataRow</Property>
</Property>
<Property Name="ItemArray">
<Property>ServiceGroup1</Property>
<Property>15</Property>
<Property>28</Property>
</Property>
<Property Name="HasErrors">False</Property>
</Object>
<Object>
<Property Name="serviceGroupName">ServiceGroup1</Property>
<Property Name="numAccounts">45</Property>
<Property Name="numDevices">69</Property>
<Property Name="RowError" />
<Property Name="RowState">Unchanged</Property>
<Property Name="Table">
<Property>System.Data.DataRow</Property>
</Property>
<Property Name="ItemArray">
<Property>ServiceGroup1</Property>
<Property>45</Property>
<Property>69</Property>
</Property>
<Property Name="HasErrors">False</Property>
而最後一件事的輸出格式。如果可以從XML中刪除多餘的膨脹，就可以看到它將數據輸出翻倍，因爲它會創建一個名爲ItemArray的節點，其中包含所有相同的信息。
我希望這很容易理解。如果您需要更多信息，請告訴我。並提前感謝您提供任何幫助。
嗯..這似乎並沒有工作，它通過一些錯誤，當我試圖運行它。它說「無效的列名」每月「。」我可能在錯誤的地方添加了它，我嘗試了2個地方，試圖將它添加到Order語句之前和之後。然後我嘗試在最初的FROM語句中添加「Monthly」作爲ReportType，我在其中抓取其他列名稱。 – chamele0n 2013-04-04 03:37:05
更新答案，添加完整的代碼，您檢查是否已經在同一位置添加常量列。 – ljh 2013-04-04 05:31:05
這很好。非常感謝。不知道如果我手動添加它時，我設法輸入錯誤信息。 – chamele0n 2013-04-04 20:50:03
