Ren,

I think the Query below might perform better for you. In my experience I have found that Group by performs better than Distinct.


God Luck.

SELECT
  Table1.Id,
  Dtable.Description
From Table1,
(Select Id, Description
 From Table2
 Group by 1, 2) Dtable
Where
 Table1.Id = Dtable.Id;

OR

SELECT
  Table1.Id,
  Dtable.Description
From Table1
Join
(Select Id, Description
 From Table2
 Group by 1, 2) Dtable
On
 Table1.Id = Dtable.Id;
