    <p>You probably used <code>scanf</code> to read <code>choice</code> before calling <code>fgets</code> to read the name. <code>scanf</code> may have left a newline in <code>stdin</code> which your code mistakes for an empty name input. If that is indeed the case, try not to use <code>scanf</code> (use <code>fgets</code> to retrieve <code>choice</code> and use <code>atoi</code> to conver to <code>int</code> or <code>strcmp</code> to compare against "1\n" etc.). The code should otherwise work, with the below modifications to account for the fact that <code>fgets</code> also reads the terminating newline into the buffer (which you probably want stripped):</p> <pre><code> #define MY_LENOF(x) (sizeof(x)/sizeof((x)[0])) char choice[3] = { 0 }; /* example of how to initialize to all NULs */ if (!fgets(choice, MY_LENOF(choice), stdin)) { fprintf(stderr, "Premature end of input\n"); exit(1); } if (strcmp(choice, "1\n") == 0) { /*Name*/ printf("\nEnter the name:"); if (!fgets(name, MY_LENOF(name), stdin)) { /* if fgets fails it leaves name unchanged, so we reset it to "" */ name[0] = '\0'; } /* good practice to use srtnlen in order not to overrun fixed buffer */ /* not necessarily a problem with fgets which guarantees the trailing NUL */ size_t nameLength = strnlen(name, MY_LENOF(name)); assert(name[nameLength] == '\0'); if (nameLength - 1 &gt; 0 &amp;&amp; name[nameLength - 1] == '\n') { /* strip trailing newline */ name[--nameLength] = '\0'; } else if (nameLength &gt;= MY_LENOF(name) - 1) { fprintf(stderr, "Name is too long\n"); exit(1); } else { fprintf(stderr, "Premature end of input\n"); exit(1); } record.nameLength = nameLength; record.name = malloc(sizeof(char)*(record.nameLength + 1)); strcpy(record.name, name); </code></pre>

    1. COProbably don't want to use `atoi`, as it performs no error checking (`sscanf` and check the return value should work, my C is rusty though). Nice answer.

    2. COcorrect. therefore, in his case (I imagine he performs no arithmetic, just checking) he should use `strcmp`

    3. CO@Bernard: `sscanf` is pretty crummy for error-checking too if you're not careful (e.g. `"%d"` will match `"123foo"`). Checking for malformed input with `strtod` and the like is much more straightforward.

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.
