Hi,

I would like to generate a unique row number ( starting from 1 ) to the
result set generated from the query below.   I know that I could insert the
results into a table with an identity column, but I need to have
a unique row number produced without doing any table inserts.


BEGIN

DECLARE @TheXML XML

SELECT

      SUBSTRING(doc.col.value('first_name[1]', 'varchar(30)'),1,30) first_name,
      SUBSTRING(doc.col.value('surname[1]', 'varchar(35)') ,1,35) surname,
      SUBSTRING(doc.col.value('title[1]', 'varchar(4)') ,1,4) title,
      SUBSTRING(doc.col.value('gender[1]', 'varchar(6)') ,1,6) gender


FROM @thexml.nodes('/jobs/applicant') doc(col)

END

Thanks
