SQL Server 2008: TOP 10 and distinct together

Question

As the title says, I\'m using SQL Server 2008. Apologies if this question is very basic. I\'ve only been using SQL for a few days. Right now I have the following query:

Answer 1

SELECT DISTINCT * FROM (

SELECT TOP 10 p.id, pl.nm, pl.val, pl.txt_val

from dm.labs pl
join mas_data.patients p    
  on pl.id = p.id
  where pl.nm like '%LDL%'
  and val is not null

)
