'x' on blob field when retrieving records

[fbeltran]

I have a query like this

select hex(blob_field) as myField from table

When the blob field is empty ('') it returns 'x'.

i'm using ADO with Visual Basic and MyODBC 3.51.
MySQL Version is 4.0.18 and SO is Win XP Pro (also happens on Windows 2K)
