Solution 2

To learn what is the benefit of SET ARITHABORT ON comment it out in the procedure and see what happens.

Or read this page : http://msdn.microsoft.com/en-us/library/ms190306.aspx[^]

and about "What is the meaning of doc(col)"

It means that create a table named doc and insert xml nodes from @xmlTbl.nodes('/DWR/Insertxml') into a column named col
So I think doc.col.value makes sense now.

Hope it helps.
