Dear Team,

I am getting error - If expression : no updating expression allowed -
while trying to update the "Data" DB.

I need to update the DB, if it is not already updated...

for $c in doc('2012')/Docs/Doc/No/@n
    return
          if (string-length(doc('Data')/Docs/Doc[No/@n=$c]/Title/Name/text()) eq 0) then
            insert node $c into doc('Data')/Docs
          else
            <l>{''}</l>

Have a nice day
