[mso] Re: Access 2002 Doesn't Link Null Data

Hi Cathy,

Thank you for the reply.

<<What is the recordsource for the existing query?  >>

The existing query extracts a subset from a single master table which contains 
records for all the people who have been members of our club since data was 
computerized about twenty years ago. The existing query merely extracts a 
single record for each currently active member. All fields in the master table 
are represented in the Active Members subset.


<<Is there a primary key for an ID in the master table?>>

No. The combination of Last_Name and First_Name fields uniquely identifies 
each member. We also have a field for middle initial, but I don't think it has 
ever been needed to resolve duplicates. We have added "Jr" to First_Name entry 
for a few individuals.


<<...more info on the master data table structure it would be helpful. >>

A single record containing about 500 bytes in 30 fields of data contains all 
the info pertinent to a single individual. We have about a thousand such 
records, but only a little over 200 records pertain to currently active 
members.


<<Are the links in this new query one to one or one to many? >>

The links are one to one. I join Last_Name in Active Members query to Last 
Name in the new query. I similarly join First_Name.


<< I was taught to build my queries from left to right,>>

I'm not sure what significance there is in the left/right placement in my 
case. How does it matter whether the master table is to the left or right of 
the Active Members query? In my case I have placed the Active Members query to 
the left of the master table. Would my results differ if I reversed the order?

Thanks for the help.
