我使用group by with rollup得到以下查询结果：
Divison Department Section Employee Name Employee ID Hours
Assets Asset Strategy Not Defined Monty Mouse 480193 64.00
Assets Asset Strategy Not Defined Frank Flint 480165 67.50
Assets Asset Strategy Not Defined 480165 131.50
Assets Asset Strategy 480165 131.50
Assets Event Centre Not Defined Sally Spoons 800192 72.00
Assets Event Centre Not Defined Randolph Smith 800199 37.50
Assets Event Centre Not Defined Petra Peters 800195 64.00
Assets Event Centre Not Defined 800195 173.50
Assets Event Centre 800195 173.50
我希望能够阻止员工ID在汇总行中复制：
Divison Department Section Employee Name Employee ID Hours
Assets Asset Strategy Not Defined Monty Mouse 480193 64.00
Assets Asset Strategy Not Defined Frank Flint 480165 67.50
Assets Asset Strategy Not Defined 131.50
Assets Asset Strategy 131.50
Assets Event Centre Not Defined Sally Spoons 800192 72.00
Assets Event Centre Not Defined Randolph Smith 800199 37.50
Assets Event Centre Not Defined Petra Peters 800195 64.00
Assets Event Centre Not Defined 173.50
Assets Event Centre 173.50
我已经阅读了有关使用union来尝试仅根据非汇总查询匹配员工的其他帖子，但这对我没有用。
我还阅读了有关使用子选择（换行）来获取员工ID的信息，但这只会导致相同的结果。
我的汇总语句按部门，部门，部门和员工姓名分组。如果我尝试将员工ID添加到此子句中，我会对员工的每次更改进行汇总。我也改变了名称和if字段的顺序，并尝试按id而不是名称进行分组，但这只是以与id相同的方式复制名称。
我在这里追逐不可能实现的梦想吗？实际上不可能以这种方式显示数据吗？任何建议都将不胜感激。

根据我的理解，在mysql.com论坛（http://forums.mysql.com/read.php?10,577674,577674#msg-577674）中发布了相同的问题，在查询时无法消除这种重复。
需要通过辅助程序语言以编程方式完成。
