连接图断开连接ORACLE

Question

下面的查询不会运行，因为我有连接图断开连接。据我了解，当你为一个表别名时，你必须先把它放在连接条件中，但是当我这样做时，我仍然得到相同的错误，有什么建议？

select 
date1.LABEL_YYYY_MM_DD as Some_Label1, 
A.Some_Field as Some_Label2, 
round(sum(D.Some_Field3)/count (*),0)as Some_Label3 
from Table_A A 
inner JOIN Table_B B ON (A.some_key = B.some_key) 
inner JOIN date_time date1 ON (A.START_DATE_TIME_KEY = date1.DATE_TIME_KEY) 
left outer join Table_C C on(C.some_GUID = A.some_ID) 
left outer join Table_D D on(D.a_ID = C.a_ID) 
where 
(1=1) 
and date1.LABEL_YYYY_MM_DD ='2015-03-30' 
and D.blah ='1' 
group by 
date1.LABEL_YYYY_MM_DD, 
A.Some_Field 
order by 
date1.LABEL_YYYY_MM_DD 
; 

根据我上面的评论，我应该改变第一内连接来B.some_key = A.some_key等等，但是我仍然得到断开...
