I get "The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified." error with the following code. I initially had two tables, ADSAREAS & CATEGORIES. I started receiving this error when I removed CATEGORIES table.

    Select Case SIDX  
     Case "ID" : SQLCONT1 = " AdsAreasID"
     Case "Page" : SQLCONT1 = " AdsAreasName"
     Case Else : SQLCONT1 = " AdsAreasID"  
End Select   
Select Case SORD  
     Case "asc" : SQLCONT2 = " ASC"
     Case "desc" : SQLCONT2 = " DESC"
     Case Else : SQLCONT2 = " ASC"  
End Select   
''# search feature --->
Select Case SEARCHFIELD  
     Case "ID" : SQLSFIELD = "AND AdsAreasID"
     Case "Ads Areas" : SQLSFIELD = "AND AdsAreasName"
     Case Else : SQLSFIELD = ""  
End Select  
Select Case SEARCHOPER  
     Case "eq" : SQLSOPER = " = " & SEARCHSTRING
     Case "ne" : SQLSOPER = " <> " & SEARCHSTRING
     Case "lt" : SQLSOPER = " <" & SEARCHSTRING
     Case "le" : SQLSOPER = " <= " & SEARCHSTRING    
     Case "gt" : SQLSOPER = " >" & SEARCHSTRING
     Case "ge" : SQLSOPER = " >= " & SEARCHSTRING
     Case "bw" : SQLSOPER = " LIKE '" & SEARCHSTRING & "%' "
     Case "ew" : SQLSOPER = " LIKE '%" & SEARCHSTRING & "' "
     Case "cn" : SQLSOPER = " LIKE '%" & SEARCHSTRING & "%' "
     Case Else : SQLSOPER = ""  
End Select  
''# search feature --->

SQL = "SELECT * FROM ( SELECT A.AdsAreasID, A.AdsAreasName, ROW_NUMBER() OVER (ORDER BY A.AdsAreasID) As Row"
SQL = SQL & " FROM ADSAREAS A"
SQL = SQL & " WHERE Row > ("& RecordsPageSize - RecordsPerPage &") AND Row <= ("& RecordsPageSize &") ORDER BY" & SQLCONT1 & SQLCONT2
