選択肢
- The area for the results because it holds the rows that the operation has produced so far and returns them to the client when the sort has finished.
- The private region of that server process which holds the data and the control information of the process and the working area of each cursor that it is executing.
- The buffer for the change records because it holds the intermediate results until the operation reaches a point where the results can be discarded.
- The shared region of the instance because it holds the blocks that the sort reads and the executable form of the statement that started the sort.
