    <p>How this works: <code>char *array[10]</code> is an array of 10 <code>char *</code> pointers (basically 10 same things as <code>token</code>).</p> <p><code>token = "testing"</code> creates static space somewhere in your program's memory at build time, and puts "testing" there. Then <em>in run time</em>, it puts address to that static "testing" to <code>token</code>.</p> <p><code>array[0] = "again"</code> does basically the same thing.</p> <p>Then, <code>strcat(array[0], token)</code> takes address in <code>array[0]</code>, and tries to add <code>token</code>'s content to string at that address. Which gives you segfault, since <code>array[0]</code> points to read-only data segment in your memory.</p> <p>How to do this properly:</p> <pre><code>char * initial = "first"; // pointer to static "first" string char * second = "another"; // another one char string[20]; // local array of 20 bytes strcpy(string, initial); // copies first string into your read-write memory strcat(string, second); // adds the second string there </code></pre> <p>Actually, if you don't want to shoot yourself in the foot, the better way to do something like the last two lines is:</p> <pre><code>snprintf(string, sizeof(string), "%s%s", initial, second); </code></pre> <p><code>snprintf</code> then makes sure that you don't use more than 20 bytes of <code>string</code>. <code>strcat</code> and <code>strcpy</code> would happily go over the limit into invalid memory, and cause another run-time segfault or something worse (think security exploits) if the copied string were longer then the destination space.</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.
