Dummy_Zero_Date_Value

Remarks

Sets up the value of the dummy zero date. This should be set to the lowest possible date value that the database supports. In most databases the default 0001-01-01 can be used. Some databases however support a different lowest possible date value.

This default value is copied to database level when logging in to the database. The actual value in use for an active connection is that on database level. This attribute merely reflects a default.
