執行這條語句，會幫你自動判斷數據庫中是否有與你要插入的記錄重複主鍵，有則更新，沒有就插入
格式如：insert into tablename(字段1，字段2，。。。。) select * from (select ? 字段1,? 字段2,.... from dual) as b on duplicate key update 字段1=b.字段1,....
例子：insert into trtb_dim_top_cats(cid,parent_cid,name,is_parent,status,sort_order,lev)
select * from (select ? cid,? parent_cid,? name,? is_parent,? status,? sort_order,? lev from dual)
as b on duplicate key update cid=b.cid,parent_cid=b.parent_cid,name=b.name,is_parent=b.is_parent,status=b.status,sort_order=b.sort_order,lev=b.lev
