Find Out Whether a Specific Column Exists in a Database Table

This snippet will allow you to check whether a certain column exists in a database table or not. Useful when you're coding against a database which schema you don't fully know. Just change the name of the column you're looking for (nameToCheck), the Connection String and the SQL SELECT statement, the bold items in this snippet.
  Dim oField ' As ADODB.Field
  Dim oRecordset ' As ADODB.Recordset
  Dim oConn ' As ADODB.Connection
  Dim nameToCheck
  Dim nameExists
  ' The column name you're looking for
  nameToCheck = "ID"
  nameExists = false
  ' Create connection
  Set oConn = Server.CreateObject("ADODB.Connection")
  oConn.Open "YourConnectionString"
  Set oRecordset = oConn.Execute("SELECT * FROM YourTable")
  For Each oField In oRecordset.Fields
    If oField.Name = nameToCheck Then
      nameExists = True
      Exit For
    End If
  Set oConn = Nothing
  Set oRecordset = Nothing
  Response.Write("Field " & nameToCheck & " found: " & nameExists)
