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.

work any better?

Maybe but please note your test program TestPgOdbc.exe
works well on my machine. I'd like to know what's happening
on your machine.

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").
