    <p>I think this should be easy, but it's evading me. I've got a many-to-many relationship between Accounts and Account Groups. An Account can be in zero or more Groups, so I'm using the standard join table.</p> <pre><code>Accounts -------- ID BankName AcctNumber Balance AccountGroups ------------- ID GroupName JoinAccountsGroups ------------------ AID GID </code></pre> <p>I'm using MS Access, FWIW. Also, this is for a low-bandwidth situation, so code optimization isn't as important as simplicity/readability.</p> <p>I'm using php as a presentation layer, so a bare-bones result from Access is fine.</p> <p>As for what to do with the multi-result situation, I actually have two things I'm trying to build. The first lists all the groups in one column thus:</p> <pre><code>Bank AcctNum Balance Groups --------|--------------|----------|---------------- Citi 930938 400 Payroll HSBC 8372933 100 Monthly, Payroll Wells 09837 800 - Chase 8730923 250 Monthly </code></pre> <p>The second is a master-detail list:</p> <pre><code>Name AcctNum Balance ------------|----------|---------- Payroll (2) 500 Citi 930938 400 HSBC 8372933 100 .................................. Monthly (2) 350 HSBC 8372933 100 Chase 8730923 250 .................................. Wells 09837 800 </code></pre> <p>For the master-detail, my plan was just to get a big result set from the db, and munge it in php as needed. Since there's going to be some significant post-processing in php anyway, maybe I should just do three separate queries and do the joining there. (Since I'm more comfortable with that language.)</p>

    1. COYour data is confusing, since you have a many-to-many join what do you to happen when there are 2+ groups associated with an account? Your output shows one line per account??

    3. CO"You're not using Access": how do you know they are not using MS Access to write Jet syntax SQL (as you do too)? How do you know they are not using Access 2007's ACE where the 'A' stands for 'Access'?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
