麻烦大家帮忙看看错在哪里了.

同一个表我查找了重复值,然后我想把重复的都显示出来.包括不重复其他字段.
就把做了inner join可是出不来结果.
中间红色的查询语句单独执行能出来结果.
请问我哪里错了?是因为用了having吗?

select * from DETAIL as A
inner join   (SELECT B.PRODT_ORDER_NO,B.ITEM_CD,B.QTY
              FROM DETAIL B
              where B.DOCUMENT_YEAR ='2014'
              AND B.ITEM_CD LIKE N'MG8%'
              AND B.PRODT_ORDER_NO IS NOT NULL
              AND B.PRODT_ORDER_NO <> ''
              AND B.SL_CD=N'SF01' AND TRNS_TYPE=N'PI'
              group by B.PRODT_ORDER_NO ,B.QTY,PRODT_ORDER_NO,B.ITEM_CD
              having(count(*))>1
              ) C
on A.PRODT_ORDER_NO = C.PRODT_ORDER_NO AND A.QTY = C.QTY


我了个去,我自己找到原因了.原来是字段有两个.居然放错字段了.
