Hi Niels,
I'm not a SQL expert, but I'm guessing this has to do with the declaration of your blob in the database, and the dictionary. Perhaps let us know how the field is declared in the dictionary, and in the SQL table, and whether it is binary in either, or both, places?
the code in NetTalk is using the database driver, so there's no special "blob" handling on my side - I'm just using normal Clarion blob behaviors.
Cheers
Bruce
