我有一个非常简单的查询，因为它只是从表中获取记录，输出是这样的：

我需要做的是根据每个ID，组，StatusType和Task的DateAdministered特定年份的最接近月末的日期，将数据重新组织成列而不是行。换句话说，如果4月份的任务有两行，我将需要这两行的最大日期以及ScoreA和ScoreB的报告。 5月，6月等都做同样的事情......
最终结果应如下所示：
ID group StatusType Task April Assessment ScoreA ScoreB May Assessment ScoreA ScoreB June Assessment ScoreA ScoreB July Assessment ScoreA ScoreB
5199 MSP Completed Follow Up Contact 4/1/2011 2 5 5/26/2011 3 7 6/30/2011 1 6 7/21/2011 2 7
我尝试过几件事，我不确定这样做的最佳方法。这几乎看起来像一个枢轴，但不需要SUM或ADD任何列，所以我不知道如果我需要一个轴，这将如何工作。
