reporting services - SQL Parameters, How to give * (ALL) a default parameter? -


i have query:

 select job,age,name + + surname fullname

now filtering (in ssrs) per full name. how set default value in full name drop down field show candidates default?

drop down field looks follows:

everyone jon patric kelly steve

you can pullback data similiar query below: 

select * (  select orderby=2,filtervalue=surname, job,age,name + + surname fullname  union  select orderby=1,filtervalue=null, null,null,null + + '<all>' fullname ) order     orderby,fullname

then send in filtervalue filter clause similiar to:

select * mytable     (@filtervalue null) or (surname = @filtervalue)
