c# - SQL 2005で2つの結果を返すストアドプロシージャの結果を組み合わせる方法は？

Question

ねえ、私はストアドプロシージャの初心者です、私は次のような手順を持っています

ALTER procedure [dbo].[list_of_employee]
(
  @employee_id int
 )
 as 
begin 
select *from project_employee_rel PE
inner join employee_details E on E.employee_id=PE.employee_id
inner join project_details P on P.project_id=PE.project_id 
where PE.employee_id=@employee_id

select * from employee_details 
where employee_id=@employee_id
end 

2つの結果を別々に返します'最初のクエリが空の行またはnullを返す場合は、2番目のクエリが実行されます。それ以外の場合は、Plzが事前に感謝します。
