How to store a multiple or a list of values returned from sp_executesql ?

Question

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..

Hi all, I am executing a dynamic sql statement using sp_executesql and this is what I am doing currently -

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

SELECT @Employee_Id AS EmployeeId,@User_Name AS UserName

But the above only gets me single value when I am getting a list of records if I run the dynamic sql query individually.How can I store the list of values returned by execution of my dynamic sql ? and returns records..and returns records..But this

Answer 1

Via a temp table.

[Update]

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!

You can insert the results of EXEC sp_executesql into a temp table or table variable.

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

Or alternatively the dynamic SQL can access a temp table declared in the parent scope (but any temp table created in the dynamic SQL itself will be out of scope as soon as the execution finishes)
