sql語句真是博大精深啊！
下面是報錯的sql語句：

運行之后：ORA-01785 ORDER BY必須是select-list 表達式的數目
我理解的是多個union連接的時候是不能夠使用order by進行排序的，因為他不可能按照每一塊給你去單獨的進行排序。因為有很多主的查詢語句。當然如果只有一個主的查詢語句是可以的
接下來，我進行了改造，發現還是不行：報ora-00907缺失右括號

原因還是，
and lb.sid=(select sid from lis_busi_transactions where contno=lb.contno and rownum=1 order by sid) 這樣寫還是不能夠按照你想象中的場景進行排序的。（具體原因自己也不是很清楚）
