Retrieving Last Record (SQL)

Dear EE community,

I've tried searching this site and Google for related solutions although I have yet to find one that works for me. So it's just as easy to write a new question I guess.

The system is for Telesales Out Calling. The .asp page retrieves a list of all customers based on an entered Part Code (product.Product_Code IN '"&SPartCodes&"'.......) and then displays them alphabetically, with their telephone no, date of last order, creation date of note and the call back category of the note.

The categories for call backs are:

<% If pm.GetItem ("CallBackStatus") = "1" Then Response.Write("01 not in") Else
If pm.GetItem ("CallBackStatus") = "2" Then Response.Write("02 call back later today") Else If ..................................<snip>
"3" = 03 call back tomorrow
"4" = 04 call back next week
"5" = 05 call back in a month
"6" = 06 call back in two months
"7" = 07 call back on another date
"8" = not interested / didn't buy
"9" = do not call again
"10" = order made

 End If %>


Now, pretty self explanatory I'm sure as to what the system is doing. Nonetheless, I'm trying to get SQL to retrieve the latest record for a particular call back back status. I can't use Max, as that would only display the higher number. And Top 1 doesn't work either because the SQL query is nested in the asp page.

Also, it's important to mention that ALL notes have a NoteID. Reckon I should exploit this in any way?

Thanks in advance.
