    <p>I am having a few issues with what is probably a reasonably simple SQL statement - unfortunately, my skills don't go as far as this and I can't get my head round it!</p> <p>I have, for example, the following tables:</p> <ul> <li>booking_record</li> <li>client</li> </ul> <p>Booking record may have many bookings for one client, they are linked via 'labelno'.</p> <p>I would like to select the clients who have booked last but not booked this . I.e. This client has booked this month last year, but hasnt booked this year.</p> <p>I only got as far as selecting either situation, for example:</p> <pre><code>Select client_.title, client_.initial, client_.surname, client_.labelno, client_.email, booking_record_.bookingdate From booking_record booking_record_ Inner Join client client_ On booking_record_.labelno = client_.labelno Where client_.email Not Like '' And Date_Format(booking_record_.bookingdate, '%m') = ?Param1 And Date_Format(booking_record_.bookingdate, '%Y') = Year(AddDate(Now(), Interval -1 Year)) Group By client_.labelno </code></pre> <p>I had a quick look at views, but this is being used within a report designer which doesn't appear to support views (or at least, not at design time). Is it possible to get what I need without the use of views?</p> <p>Thanks, Daniel.</p>

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.
