問題文
A column of the target has to carry the moment at which the row was applied, read from the target side rather than from the trail. Which column-conversion function does that, and which Replicat modes may use it against a non-Oracle target?
選択肢
- A function running a statement of its own before the row is applied, open against a non-Oracle target to classic mode, to a parallel Replicat and to a coordinated one
- Whichever reads the environment for the moment of the apply, open against a non-Oracle target to classic mode, to a parallel Replicat and to a coordinated one
- The one added in this release for mapping to a function of the database, and against a non-Oracle target it is open to classic mode, to a parallel Replicat and to a coordinated one
- That one reading the environment for the moment of the apply, open against a non-Oracle target to integrated mode alone
