Body
To get a limit, without using the <code>limit</code> keyword, you can impose a count. For example, given the table definition <pre><code>create table cars (id int, carBrand char(10), carModel char(10)); </code></pre> this will give you all the Car Models for the top 2 Car Brands <pre><code>select cars.carBrand, cars.carModel from cars where ((select count(*) from (select distinct carBrand from cars) as carBrands where carBrands.carBrand < cars.carBrand) < 2) order by cars.carBrand, cars.carModel; </code></pre> This creates an inline table just listing the <code>carBrands</code> and then joins this back to cars to get the list of all cars that are in the top 2 brands. The <code>count(*) .... < 2</code> enforces the limit. Consider <code>'Ford'</code>, for example, in your above data. In '<code>Ford'</code>'s case, there are 3 brands that are <code>< 'Ford'</code> alphabetically, so the <code>count(*)</code> above = 3. Since 3 is not less than 2, no <code>'Ford'</code> cars appear in the output. The output on your test data would be: <pre><code>CARBRAND CARMODEL Alfa Romeo Guilietta Alfa Romeo Mito Audi A3 Audi R8 Audi TT </code></pre> Now, you didn't say how you wanted to pick the 2 brands -- you just listed Ford and Fiat in your example -- I don't know how you happened to pick those. If you want something other than alphabetical criteria for ordering, that's doable, but harder.

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.
