    <p>The simplest solution is to plainly use a special buffering class and overload the output operators needed:</p> <pre><code>struct buffer_class { // The data needed... }; inline buffer_class&amp; operator&lt;&lt;(buffer_class&amp; buffer, const std::string&amp; s) { // Code to add the string to the buffer return buffer; } inline buffer_class&amp; operator&lt;&lt;(buffer_class&amp; buffer, const uint8_t ub) { // Code to add the value to the buffer return buffer; } inline buffer_class&amp; operator&lt;&lt;(buffer_class&amp; buffer, const int8_t sb) { // Code to add the value to the buffer return buffer; } </code></pre> <p>Add more operator overloads for the all the data needed.</p> <hr> <p>For example, it could be like this:</p> <pre><code>struct buffer_class { std::vector&lt;int8_t&gt; data; }; inline buffer_class&amp; operator&lt;&lt;(buffer_class&amp; buffer, const std::string&amp; s) { for (const auto&amp; ch : s) buffer.data.push_back(static_cast&lt;unt8_t&gt;(ch)); return buffer; } inline buffer_class&amp; operator&lt;&lt;(buffer_class&amp; buffer, const uint8_t ub) { buffer.data.push_back(static_cast&lt;int8_t&gt;(ub)); return buffer; } inline buffer_class&amp; operator&lt;&lt;(buffer_class&amp; buffer, const int8_t sb) { buffer.data.push_back(sb); return buffer; } </code></pre> <p>Then you could use it like:</p> <pre><code>buffer_class my_buffer; buffer &lt;&lt; std::string("Hello") &lt;&lt; 123: // The raw data can now be accessed by `my_buffer.data.data()` </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
