    <p><code>I'm guessing int's are allowed less bits than constants?</code></p> <p>yes, Numeric constants are high-precision values. An <code>int</code> in any language doesn't have near the precision of other numeric types.</p> <p><code>Which language is alluded to?</code></p> <p>No clue but it is backwards from C and Java where <code>( )</code> is required and <code>{ }</code> is optional.</p> <p><code>Why do we need the word type and the word struct? What was I supposed to expect?</code></p> <p>If you're familiar with C, then it does what you'd expect.</p> <p><code>Why implicit zeroes in the constructor?</code></p> <p>It's not implicit in the contructor only. Look at this</p> <pre><code>var i int fmt.Println(i) </code></pre> <p>This prints out <code>0</code>. This is similar to something like java where primitive types have an implicit default value. booleans are false, integers are zero, etc.</p> <p><code>Make? Are there constructors? What's the difference between new and make?</code></p> <p><code>make</code> accepts additional parameters for initializing the size of an array, slice, or map. <code>new</code> on the other hand just returns a pointer to a type.</p> <pre><code>type Data struct {} // both d1 and d2 are pointers d1 := new(Data) d2 := &amp;Data{} </code></pre> <p>As for <code>are there constructors?</code>, only if you make and reference them. This how one normally implements a constructor in Go.</p> <pre><code>type Data struct {} func NewData() *Data { return new(Data) } </code></pre> <p><code>What's the %v formatter stand for? Value?</code></p> <p>Yep</p> <p><code>I return error values when a function fails? ... Why would they design it like that?</code></p> <p>I felt the same way at first. My opinion has changed though. You can ignore errors from the std library if you like and not bother with it yourself, but once I had a handle on it, I personally find I have better (and more readable) error checking.</p> <p>What I can say is when I was doing it wrong, it felt like repetitive error handling that felt unnecessary. When I finally started doing it right... well, what I just said above.</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.
