Hi Folks,
Is there a simple way to program the order by clause in FLWOR to make it
optional based on parameters? I have a web page that I want to sort as
indicated by the user.
For example, this code illustrates what I'd like to do but doesn't work:
let $sort-option := "a descending"
return
for $row in $rows
let $a := $row/a/text()
let $b := $row/b/text()
order by {if ($sort-option eq "a ascending") then $a ascending else
$default}
return <tr><td>{$a}</td><td>{$b}</td></tr>
Thanks!
Tim Meagher
