Duplicate Entries In The Resulting Table

Hi! I am joining 3 tables in SQL , I am getting the results I want exept it's duplicated. So the resultinmg table fom my stored procedure has 3 rows that have the same bulletin. How do I filter the storedprocedure to output only the rows that don't have duplicate entries for the column 'Bulletin' Thanks.

Here is my stored procedure:PROCEDURE [dbo].[spGetCompBulletins]

@Userid uniqueidentifier OUTPUT,@DisplayName varchar(200)

 

AS

 

SELECT *

FROM dbo.UserProfile INNER JOIN

dbo.bulletins ON dbo.UserProfile.UserId = dbo.bulletins.Userid INNER JOINdbo.Associations ON dbo.Associations.BusinessID = dbo.bulletins.Userid WHERE UserProfile.DisplayName=@DisplayName

and Userprofile.Userid = @Userid ORDER BY Bulletins.Bulletin_Date

Return
