RE: Hex '00' to Hex '40'?

["Simon Coulter" <shc@xxxxxxxxxxxxxxxxx>]

Hello Brad,

Can you explain this a bit more?  The web page (program) stores the received 
data in SQL Server 
on NT and DataMirror is used to propagate the SQL Server tables to the AS/400.  
Which fields 
are being translated incorrectly?  NULL fields are coming in as blanks? X'00' 
fields are coming 
in as blanks? NULL fields that happen to be initialised to X'00' by SQL Server 
are coming in as 
blanks?

Which version of DM are you using?  For a while they could not handle NULL 
fields except via 
SQL.  Do you have any exit programs running in DM to convert data or handle the 
updates (either 
%USER functions or option 15(?) from the file definition panel)?  Have value 
translations been 
defined for these files? 

A little more information is needed.  For instance, for a given record, what 
does it look like 
in SQL Server and what does it look like in DB2/400?

Personally, I think using a toy database is the root of the problem but then 
what would I know?

Regards,
Simon Coulter.
