我一直有相当的时间试图弄清楚这一点。让我试着解释我正在努力完成的事情，希望我能够清楚。Powershell SQL查询结果convertto-XML
我向MSSQL数据库发送两个查询并接收它们。下面的代码是完美的，但是我想在写入XML文件之前操作XML的格式。我目前得到3列（serviceGroupName，numAccounts，numDevices）我想完成以下两件事之一：
1）添加一个名为“ReportType”的新列，并填写“Monthly”或“Total”，具体取决于如果它是foreach循环的第一遍或第二遍（SQLQuery1是月度报告，并且SQLQuery2是自开始以来的总数）
2）创建一个新的PSObject并使其填充相应的信息，例如它接收的数据（serviceGroupName，numAccounts，numDevices）
以下是我目前的代码。正如我所说，它确实工作，它产生了一个XML，但如果可能的话，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)

$OutputHeader2 = "Total Counts"
$SqlQuery2 = @"

"@
$sqlQueries = @($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
}
}
这里是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>
而最后一件事的输出格式。如果可以从XML中删除多余的膨胀，就可以看到它将数据输出翻倍，因为它会创建一个名为ItemArray的节点，其中包含所有相同的信息。
我希望这很容易理解。如果您需要更多信息，请告诉我。并提前感谢您提供任何帮助。
嗯..这似乎并没有工作，它通过一些错误，当我试图运行它。它说“无效的列名”每月“。”我可能在错误的地方添加了它，我尝试了2个地方，试图将它添加到Order语句之前和之后。然后我尝试在最初的FROM语句中添加“Monthly”作为ReportType，我在其中抓取其他列名称。 – chamele0n 2013-04-04 03:37:05
更新答案，添加完整的代码，您检查是否已经在同一位置添加常量列。 – ljh 2013-04-04 05:31:05
这很好。非常感谢。不知道如果我手动添加它时，我设法输入错误信息。 – chamele0n 2013-04-04 20:50:03
