Question

我有以下代码返回我需要的内容，但我很难将其输出到一个表格，我可以从中进一步查询。

$instances =  invoke-sqlcmd –ServerInstance "myserver" –Database "my db" –query "select instanceconnectname from [dbo].[smytable] WHERE InstanceConnectName LIKE '%CLU%' and connect = 1"
Write-Host $instances.instanceconnectname
foreach ($svr in $instances.instanceconnectname){
    $dt = new-object "System.Data.DataTable"
    $cn = new-object System.Data.SqlClient.SqlConnection "server=$svr;database=master;Integrated Security=sspi"
    $cn.Open()
    $sql = $cn.CreateCommand()
    $sql.CommandText = "SELECT @@SERVERNAME AS ServerName, SERVERPROPERTY('ComputerNamePhysicalNetBIOS') As ActiveNode"
    $rdr = $sql.ExecuteReader()
    $dt.Load($rdr)
    $cn.Close()
    $dt | Format-Table -autosize
}

我一直在阅读一些自定义函数，那是唯一可以做到这一点的方法吗？我以为我可以做一些SQL插件，但没想出怎么做。

我将输出到DataSet，然后您可以进一步查询，而不是输出到DataTable。 e.g：

$cn = new-object System.Data.SqlClient.SqlConnection "server=$svr;database=master;Integrated Security=sspi"

#Create the SQL Command from a connection string
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "SELECT @@SERVERNAME AS ServerName, SERVERPROPERTY('ComputerNamePhysicalNetBIOS') As ActiveNode"
$SqlCmd.Connection = $cn

#Create the SQL DataAdapter
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd

#Fill the DataSet
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)

现在将它放在DataSet中，您可以查询它，如下所示：

$DataSet.tables[0].select("ServerName like 'Bob%'")

希望这足以让你开始......

将结果输出到SQL表
