SQL Server - INNER JOIN WITH DISTINCT

Question

I am having a hard time doing the following:

select a.FirstName, a.LastName, v.District
from AddTbl a order by Firstname
inner join (select distinct LastName         


        

Answer 1

Try this:

select distinct a.FirstName, a.LastName, v.District
from AddTbl a 
  inner join ValTbl v
  on a.LastName = v.LastName
order by a.FirstName;

Or this (it does the same, but the syntax is different):

select distinct a.FirstName, a.LastName, v.District
from AddTbl a, ValTbl v
where a.LastName = v.LastName
order by a.FirstName;
