I'm getting #deleted entries in resultsets from ODBC since installing SQL 7

A. Several possibilities - 

1. Could be a bug with numeric/decimal fields that only occurs with ODBC driver 3.70.0623. Upgrade to 3.70.0690 which comes with SQL 7 SP1 and/or MDAC 2.1 SP2.

2. PSS ID Number: Q128809

When you retrieve, insert, or update records in an attached ODBC table,
each field in a record contains the "#Deleted" error message. When you
retrieve, insert, or update records using code, you receive the error
message "Record is deleted."


The Microsoft Jet database engine is designed around a keyset-driven model.
This means that data is retrieved, inserted, and updated based on key
values (in the case of an attached ODBC table, the unique index of a

After Microsoft Access performs an insert or an update of an attached ODBC
table, it uses a Where criteria to select the record again to verify the
insert or update. The Where criteria is based on the unique index.
Although numerous factors can cause the select not to return any records,
most often the cause is that the key value Microsoft Access has cached is
not the same as the actual key value on the ODBC table. Other possible
causes are as follows:

- Having an update or insert trigger on the table, modifying the key

- Basing the unique index on a float value.

- Using a fixed-length text field that may be padded on the server with
the correct amount of spaces.

- Having an attached ODBC table containing Null values in any of the
fields making up the unique index.

These factors do not directly cause the "#Deleted" error message. Instead,
they cause Microsoft Access to go to the next step in maintaining the key
values, which is to select the record again, this time with the criteria
based on all the other fields in the record. If this step returns more than
one record, Microsoft Access returns the "#Deleted" message because it does
not have a reliable key value to work with. If you close and re-open the
table or choose Show All Records from the Records menu, the "#Deleted"
errors are removed.

Microsoft Access uses a similar process to retrieve records from an
attached ODBC table. First, it retrieves the key values and then the rest
of the fields that match the key values. If Microsoft Access is not able to
find that value again when it tries to find the rest of the record, it
assumes that the record is deleted.


The following are some strategies that you can use to avoid this behavior:

- Avoid entering records that are exactly the same except for the unique

- Avoid an update that triggers updates of both the unique index and
another field.

- Do not use a Float field as a unique index or as part of a unique index
because of the inherent rounding problems of this data type.

- Do all the updates and inserts by using SQL pass-through queries so
that you know exactly what is sent to the ODBC data source.

- Retrieve records with an SQL pass-through query. An SQL pass-through
query is not updateable, and therefore does not cause "#Delete" errors.

- Avoid storing Null values within any field making up the unique index of
your attached ODBC table.


Steps to Reproduce Behavior

1. Open the sample database Northwind.mdb (or NWIND.MDB. in Microsoft
Access 2.0)

2. Use the Upsizing Tools to upsize the Shippers table.

NOTE: This table contains an AutoNumber field (or Counter field in
Microsoft Access 2.0) that is translated on SQL Server by the Upsizing
Tools into a trigger that emulates a counter.

3. Open the attached Shippers table and enter a new record. Make sure
that the record you enter has the same data in the Company Name field
as the previous record.

4. Press TAB to move to a new record. Note that the "#Deleted" error fills
the record you entered.

5. Close and re-open the table. Note that the record is correct.
