Summary: Error when updating a TIMESTAMP column with NULL using ADODB

Initial Comment:
We are having problems setting TIMESTAMP fields to "Null" using ADODB (from Visual Basic 6)

The attached example doesn't work, it reports an invalid date/time-value.

Setting the field to "null" with an SQL-statement works ("update ..."). It doesn't work with 08_02_0200's Unicode version. The ANSI version works as expected.

The server is running under Linux in version 8.2.0, the clients are running under Windows XP SP2.

Message:
Instead of recordset.Update, does connection.Execute work any better?

e.g.
conn.Execute "UPDATE SET my_ts_field=NULL"

Message:
I just downloaded the new drivers (2007-03-21) and repeated the test. Now I get an error "-2147217887". I'll try to translate the error message: "Error in a OLE DB action that consists of multiple steps.". The error occurs when the test application tries to set the field value ("objRs.Fields(txtTableCol.Text) = Null").
