How have you joined the two tables? Which columns are you comparing?

Hi,

this stored procedure will if not put any parameter or giving single or both parameter. it is flexible to run by any condition.

Please arrange proper table join & select query based on your requirement because you did not provide the proper table structure.

SQL

create procedure search
@Device varchar(50)=NULL,
@@Category varchar(50)=NULL

as 

select t1.Device, t1.Category, t1.Date,t1.Company
t1.PersonName,t1.Reason
FROM table1 T1
JOIN table2 T2 ON T1.ID=t2.Id

WHERE Device=ISNULL(@Device,Device) AND Category=ISNULL(@Category,Category)
