data length more than ...

Hello
I have problem with reading from XML when XML is to large.
Program delare 1-n variables where is declaration but can no make more
delarations than length 8000 :((

drop table tblBooksEx

If you make an SP(stored Procedure) out of the Code , you can send
xml to SP as a text parameter

Need to do in an SP . You need to send text from client side. Sending
text within sql server not possible for SQL 2000

create proc usp_getxml
@xmltext TEXT
as
Declare @hdoc INT
--Create XML document.
EXEC sp_xml_preparedocument @hdoc OUTPUT, @xmltext
