倾囊求一个复杂的统计SQL
表AA 
 区域,	大类,	功能1,	功能2,	货号,	规格,	销售数量 
 1,	IOPD,	sing,	A,	1234,	11-11,	2 
 1,	IOPD,	sing,	A,	1234,	11-12,	2 
 1,	IOPD,	sing,	A,	6780,	11-22,	3

 。。。。。。。。。。。。。。。   
 要求统计如下: 
 大类,功能1\功能2,区域1货号数量,区域1(货号+规格数量),销售数量   ,区域2货号数量,区域2(货号+规格数量),区域2销售数量 
 IOPD,	sing\A,	2,	4,	12,	      2,	4,	12 
 IOPD,	sing\B,	1,	2,	11,                     2,	4,	12 
 。。。。。。。。。

------解决方案--------------------都是交叉表的问题。 
 之前已经很多人问过相似的问题了。
