My first thought would be to make sure that there is no duplicate in the
first record.

My second thought is wondering how do you think we may help you without
having any details on the piece of VBA code doing this little piece of
magic.

I have a Microsoft Access ADP that goes against an MS SQL Server 2000
database.

Within this MS Access ADP I have a recordset (forward only, read only,
cachesize 1) that is the result of a SELECT. . .WHERE EXISTS query. This
recordset is gone through to create corresponding records (1-for-1) in
another recordset which is open for write (forward only, optimistic
locking,
cachesize 1) to an empty SQL Server 2000 table.

This works fine if the first recordset returns 5 or fewer records.
However,
if the first recordset returns 6 or more records, then the actual number
of
records that appear in the SQL Server 2000 table are short by 2: In other
words, if 6 records are expected I only get 4, if 7 records are expected I
only get 5, etc. !

Debugging shows that the RecordCount is correct, that AddNew is executed
the
correct number of times, and that Update is executed the correct number of
times. Yet, when I look over at the resulting table using Enterprise
Manager,
it's 2 records short!

There's nothing wrong with the WHERE EXISTS query either: It works
perfectly
in other contexts. Also, CacheSize has nothing to do with the problem: In
addition to the original value of 1 I tried -1, 20, and 100.

Any ideas? Any help you could give would be greatly appreciated!
