You can do this through vb.net or you can do it through your SQL query.

If you are not going to use a stored procedure, I would recommend sorting through it from your code, and just selecting all of what you need.

SELECT * FROM tbl

<script language="vb" runat="server">
Function chkArgs(ByVal mpn As Short, ByVal aml As Char, ByVal onhand As Integer, ByVal demand As Integer)
  If aml = "P" And onhand >= demand Then
    'Do your data here
  ElseIf aml = "A" And onhand >= demand Then
    'Do your data here
  End If
End Function
</script>

Just call the function everytime you need the data. chkArgs(<%# Eval("mpn") %>,<%# Eval("aml") %>,<%# Eval("onhand") %>,<%# Eval("demand") %>)
