UPDATE : This is what I did- 

   set @dyn_sql = '
                        select
                                @UserName=UserName
                        from
                        (
                        select 
                                E.ID as EmployeeID,
                                E.UserName as Username
                            from   
                                Leaderboard K
                                    inner join Employee E on  K.EmployeeId = E.Id
                                    inner join INFO KD on KD.EmployeeId=E.Id
                                    where  E.CompanyId=4
                         ) as d1'
DECLARE @leaderboards TABLE
( 
 UserName varchar(50)
) 
set @params='@Employee_Id int, @UserName varchar(200) OUTPUT'
INSERT INTO @leaderboards (UserName)
EXEC sp_executesql @dyn_sql, @params,@EmployeeId=@Employee_Id OUTPUT,@UserName = @User_Name OUTPUT

SELECT * from @leaderboards

But this is not returning records although if I see the query is right and returns records..

大家好，我正在使用 sp_executesql 执行动态 sql 语句，这就是我目前正在做的事情 -

EXEC sp_executesql @dyn_sql, @params,@EmployeeId=@Employee_Id OUTPUT,@UserName = @User_Name OUTPUT

SELECT @Employee_Id AS EmployeeId,@User_Name AS UserName

但是，如果我单独运行动态 sql 查询，则当我获取记录列表时，上述内容只能获得单个值。如何存储执行动态 sql 返回的值列表？并返回记录..并返回记录..但这

通过临时表。

[更新]

declare @sql nvarchar(max)
  set @sql = '
select 
    E.ID as EmployeeID, --doesn't really matter how you name them, it's the order that matters
    E.UserName as Username -- and this order should match the order of columns in the insert statement
from   
    Leaderboard K
        inner join Employee E on  K.EmployeeId = E.Id
        inner join INFO KD on KD.EmployeeId=E.Id
        where  E.CompanyId=4
'
DECLARE @LeaderBoard TABLE
( 
    EmployeeId int, 
    UserName varchar(50)
) 
INSERT INTO @LeaderBoard (EmployeeId, UserName)
exec sp_executesql @sql

select * from @LeaderBoard

--Hurray, we made it!

您可以将结果插入EXEC sp_executesql到临时表或表变量中。

DECLARE  @t TABLE
(
a INT,
b INT
)
INSERT INTO @t (a,b)
EXEC sp_executesql N'SELECT 1, 2 UNION SELECT 3, 4 '

或者，动态 SQL 可以访问在父范围内声明的临时表（但在动态 SQL 本身中创建的任何临时表将在执行完成后立即超出范围）
