varchar(8000) limits,how to overcome it in storedprocedure?

Hello Expert,

I face problem where my varchar stores data which over 8000 char.
So i cant execute my storedprocedure. got error
May i know how to overcome this varchar(8000) limits?
The Following is my storedprocedure :

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go




Alter PROCEDURE [dbo].[MySP_ErrorLog]
AS
DECLARE @strXML varchar(8000)
DECLARE @idoc int
DECLARE @QueueID varchar(20)
DECLARE @XMLDATA varchar(8000)



DECLARE TB_LnItem_Cursor CURSOR FOR
Select QueueID, XMLData from tb_batchpocreation_Queue
Open TB_LnItem_Cursor

FETCH NEXT FROM TB_LnItem_Cursor INTO @QueueID, @XMLDATA
WHILE (@@fetch_status=0)
BEGIN
SET @strXML = @XMLDATA

EXEC sp_xml_preparedocument @idoc OUTPUT, @strXML
SELECT RegionCode
FROM OPENXML(@idoc, '/BatchPOCreation/Records/Record/RegionCode')
WITH (RegionCode varchar(250)
 
  )
EXEC sp_xml_removedocument @idoc

FETCH NEXT FROM TB_LnItem_Cursor INTO @QueueID, @XMLDATA

END
CLOSE TB_LnItem_Cursor
DEALLOCATE TB_LnItem_Cursor


My @XMLDATA stores over 8000 chars.

what is the datatype of XMLData in yourtable TB_LnItem_Cursor?
I think it is text or ntext
in that case you have to define 2 or three variables of varchar(8000)
and move first(8000) characters in variable1 and the rest in variable2

EXEC sp_xml_preparedocument @idoc OUTPUT, @strXML1 + isnull(@strXML2,'')

What version of MSSQL are you running ?

SQL2k5 supports both a varchar(max) (= virtually unlimited string) and a native xml datatype

if sql server 2000 really cant do it, then i plan to directly read the xml data from crystal report.
But i dunno wat is the step to read the xmldata field which is stored in  tb_batchpocreation_Queue table?
Coz i need to retrieve Data inside this xmlData field.

The Data in xmldata field is like this:

<BatchPOCreation><Records><Record><ID>1</ID><RegionCode>SEL</RegionCode></Record></Records></BatchPOCreation>

Honestly, I never really played with XML a lot as I'm lost why people would want to 'explode data' into a 'readable format' only to feed it to something that needs to convert it back to a record set.
Anyway, wouldn't it bee possible to use the prepare document statement as to create the output in one go and have that returned directly to Crystal Reports ?

(afaik Crystal Reports gladly acceppets recordsets, so why bother going via XML in the first place ? ... my 2 (heavily biased) cents )

You could use multiple varchar(8000) variables, nad test the length each time you add something to them. If the first gets to 8000 characters, start filling the second, etc.

try this

CREATE PROCEDURE [dbo].[MySP_ErrorLog]
 @strXML varchar(8000)  = null
AS
BEGIN
    DECLARE @idoc int
    DECLARE @QueueID varchar(20)
    DECLARE TB_LnItem_Cursor CURSOR FOR
    Select QueueID               --- Fetch only the QueID
