Populate a dataset in a foreach loop

Hi,

I am trying to populate a dataset in foreach loop, but I have difficulties getting it working.

I have a set of plan_handles in a dataset. Now I want to go through them and execute a query to get the details about the plans. The result should get into a dataset (that I later will SqlBulkCopy into a database).

I have this code. I can see that the queries are executed against the server, but when I look at $Plans.Tables[0] it only contains one row.

  foreach ($Plan in $PlanHandles.Tables[0])
  {
    $PlanHandle = $Plan["plan_handle"]
    $SqlSourceConnection.Open()
    $SqlCmdPlanGet = New-Object System.Data.SqlClient.SqlCommand("SELECT GETDATE() AS [timestamp], @plan_handle AS plan_handle, [dbid], objectid, number, encrypted, query_plan FROM sys.dm_exec_query_plan(@plan_handle)",$SqlSourceConnection)
    [void]$SqlCmdPlanGet.Parameters.Add("@plan_handle",$PlanHandle)
    $SqlCmdPlanGet.CommandTimeout = 30
    $SqlAdapterPlanGet = New-Object System.Data.SqlClient.SqlDataAdapter($SqlCmdPlanGet)
    $Plans = New-Object System.Data.DataSet
    $SqlAdapterPlanGet.Fill($Plans)
    $SqlSourceConnection.Close()
  }

I have been reading about it and I understand, that it is something with that I should specify the datatable, but I am not sure how to get the code right.
