The fact is that we are talking about ODBC here.
The difference between a table and a view is that in the table one
record as one value of the sequence, forever. With a linked view
in access, if I sort the table or query it in anyway new sequence
numbers are given to all the fields.

I know about all these problems with Access, and all my tables are
configured in such a way that the #DELETED problem never arises.
The problem is with this view. (sorry to insist, but it really
does matter here that the linked table is a view)
