  Let's suppose I have $objTable, a SQL Server table object, with 3 columns:

  nUnitType_Id

  cE_Descritpion

  cF_Description

  I swear that at one point a few months ago, this bit of code was returning $DescCols containing the expected 2 columns, but for the life of me I can't get it to work now... What am I missing here?

  $DescCols = $objTable.Columns | ?{(($_.Name).Substring(0, 3) -like "c[EF]_*") `

  -and ((group ($_.Name).Substring(3)).Count -eq 2)}

  $DescCols

  Thanks!

  Figured it out.

  $DescCols = @()

  $MultiCols = $objTable.Columns | %{$_.Name.Substring(3)} | group | ?{$_.Count -eq 2}

  if ($MultiCols)

  {

  foreach ($Row in $MultiCols)

  {

  $DescCols += $objTable.Columns | ?{$_.Name -like "*$($Row.Name)"} | select name

  }

  }
