Without a way of getting the autoincrement from the ODBC driver, there
will always be cases, when adding data to a table through a linked
table, where the data that appears onscreen is not the one that has been
added to the table. And this until you requery the whole table.
- After an insert, Microsft ODBC driver issues a "SELECT @@IDENTITY".
- After an insert, Postgresql ODBC driver reads the data based on the
values that have been inserted. There are cases were these values
already existed in the table before the insert, and so the autoincrement
fetched may not be correct.
Is there anything that can be done at the driver level?
