inner join和case能一起使用吗?
Select   P.*,T.Name   From   PartsCTE   as   P 
 	inner   join    
    CASE   TypeId 
 		   WHEN   1   THEN   [Regional] 
                            WHEN   2   THEN   [Tours] 
    end   as   T 
 on   T.ID=P.ObjectId   
 Regional,Tours为表名
------解决方案--------------------当然可以,但是用法不对
------解决方案--------------------Select  
     P.*, 
     case TypeId  
       when 1 then (select Name from [Regional] where ID=P.ObjectId) 
       when 2 then (select Name from [Tours] where ID=P.ObjectId) 
     end as Name 
 From  
     PartsCTE as P
------解决方案--------------------还可以用union   
 select P.*,T.Name from PartsCTE P,[Regional] T where T.ID=P.ObjectId 
 union all 
 select P.*,T.Name from PartsCTE P,[Tours]    T where T.ID=P.ObjectId
------解决方案----------------------这样写 
 Select P.*,T.Name  
 From PartsCTE as P inner join 
 ( 
 select 1 as sort,id,name from [Regional] 
 union  
 select 2 as sort,id,name from [Tours] 
 )t 
 on T.ID=P.ObjectId and t.sort = p.typeid
