Query taking long time with DISTINCT

Question

I\'m using Microsoft Access 2003. One form in my project takes a long time to appear to users.

This is the applicable query:

SELECT DISTINCT tb_Konze         


        

Answer 1

The use of distinct is essentially doing a group by so you only get "unique" records. If you don't have any duplicate records then this is not needed.

I would place my focus on your joins, instead of the distinct clause.
