Description: Setting timestamps to null doesn't work with PDO
Details:

Hi!

We are having problems, setting timestamp fields to "Null" with PDO (Visual
Basic 6)

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

-----------------------------
strSql = "Select * From auftrag Where nummer In('0131') Order By nummer"

Set ds1 = objHMVBDV.ADOConnection.OpenRecordset(strSql, adOpenDynamic,
adLockOptimistic)
ds1.Fields("erloeseaufgebautam") = Null
ds1.Update
Set ds1 = Nothing

-----------------------------
Setting the field to "null" with an SQL-statement works ("update ..."). It
doesn't work with 8.2.0 and 8.2.1 but does work with 8.0.x.

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