  Great article, thanks.

  It appears there's a small error though, Table 1 is missing for me.

  Both Table 1 and Table 2 appear to be missing for me.

  A useful article, but I think you leap to the CROSS APPLY example with nodes a little early. I only understood this having first seen an example elsewhere that used .nodes against an xml @variable - and seeing that this in itself returns a table as its result set

  Perfect example for .nodes. Can we take it one step further?

  Instead of concatenating First Name & Last Name, can we produce the same rowset with two columns?

  First Name

  Last Name

  So the results might read:

  ID FirstName LastName

  1 John Doe

  1 Jack Smith

  2 Bob Jones

  2 Henrietta Jones

  If you want separate columns for first name and last name:

  SELECT

  ci.ClientID,

  Person.query('.') AS Person,

  Person.value('FirstName[1]','varchar(20)') AS First_Name,

  Person.value('LastName[1]','varchar(20)') AS Last_Name

  FROM

  ClientInfo ci

  CROSS APPLY

  Info_untyped.nodes('/People/Person') AS People(Person)

  ;
