Thread: help with troublesome query

I have three tables customers which 1-many with requests which is 1-1 
with applications. all customers have at least one request but not all 
requests have an application.

I want a query to return all the customers and their application data if 
they have any ( or else null). So this is like a left join of customers  with applications but I do not want multiple
rowsof customers UNLESS 
 
they have an application.

thanks

I think you want to first do an inner join of requests and applications
and then left join the customers and the previous join.
