Linkedserver , Navision C/ODBC, Null columns Error

hello
i am having a few problems with Linkedserver and Navision Financials.
Most of the tables in navision (Customer, Prospect, Sales Line etc) have
DateTime columns that may contain nothing (null).
if i try to select these records i will get an error but i need access to
these columns so i can find out it the record has been updated recently.
the error is:
[Microsoft][ODBC Sql Server Driver][SQL Server]OLE DB error trace
[Non-interface error: Unexpected NULL value returned for the column:
ProviderName='MSDASQL', TableName'[Rowset_1]',ColumnName='Date_Completed'].
so how can i retrieve records with null columns? can i specify somewhere in
sql statements to ignore null columns or something? below is a sample sql
query.
also note that the funtion IFNULL dont work for me, i will still get an
error
example sql statement:
DBCC TRACEON (8765)
SELECT * FROM
OPENQUERY(NAVISION,'SELECT
* FROM Sales_Header WHERE Document_Type = ''Order'' ')
if i replace * with specific column names (No_ Name_ etc) it will work fine,
as long as Date_Completed isnt requested (in this case).
i am develping a navision client for users on the road (using XDA II ppc's)
that will connect over GPRS and webservices so this is why i require the
DateTime fields, so the user will know if the records are upto date in the
SqlCe database.
Regards,
Ricardo Meechan
I am having the exact same problem. Have you gotten any further in resolving this issue?

servers in SQL 2005.

The below works perfectly in SQL 2000.
I have setup a Linked server to Navision 4.01 with a OLE DB provider for ODBC.
I get below errors when I do the following:
EXEC sp_addlinkedsrvlogin 'nav4', 'true'
Select name from openquery(nav4, 'select navn from country')
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "nav4" reported an error. The
provider reported an unexpected catastrophic failure.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for
linked server "nav4".
Above also happens no matter what I try, can anybody help ?
(I have also tried to create the linked server with sp_addlinkedserver, this
dont work either)
/Brian
May check the compatible driver is used for NAVSION and check KBA
http://support.microsoft.com/kb/818182 fyi.

This update does not work, I have installed SP1 and these files are newer
than the version
that can be downloaded from below. (it also not worked before installing the
sp1)
But thanks for your suggestion
