> The row_number() windowing function does not behave like other expressions which appear in the SELECT LIST. With other SELECT LIST expressions, you can build up more complicated expressions.  If we decide not to lift this limitation, we should probably at least mention it in the ROW_NUMBER section of the Derby Reference Manual. 
> The following query works:
> select a + 1 as c, row_number() over () as row_number
> from t
> where a > 100 and a < 111
> ;
> The following query raises an error:
> select a, (row_number() over ()) + 1 as row_number
> from t
> where a > 100 and a < 111
> This is the error I see: "ERROR 42X01: Syntax error: Encountered "over" at line 2, column 25."
