    <p>An alternative to what <a href="https://stackoverflow.com/users/711105/lightstep">lightstep</a> suggested, is to prepare query strings and then call a function that first writes the query to the log and only then calls real execute(). I personally use QString::arg() and "%number" for arguments to make a query string instead of bindValue().</p> <p>Let's sum things up:</p> <p>Solution #1 (<a href="https://stackoverflow.com/users/711105/lightstep">lightstep</a>)</p> <blockquote> <p>I came up with this workaround:</p> <pre><code>QString getLastExecutedQuery(const QSqlQuery&amp; query) { QString str = query.lastQuery(); QMapIterator&lt;QString, QVariant&gt; it(query.boundValues()); while (it.hasNext()) { it.next(); str.replace(it.key(),it.value().toString()); } return str; } </code></pre> </blockquote> <p>Solution #2 (me):</p> <pre><code>// my helper function #define SQLDB_SHOW_QUERIES #define SQLDB_LOG_QUERIES #define SQLDB_LOG_FILENAME "sqlite.db.log" bool executeQuery(QSqlQuery&amp; queryObject, const QString&amp; query) { bool result = true;; #ifdef SQLDB_SHOW_QUERIES std::cout&lt;&lt;query.toStdString()&lt;&lt;std::endl; #endif #ifdef SQLDB_LOG_QUERIES std::fstream fs_log; fs_log.open(SQLDB_LOG_FILENAME,std::ios::out|std::ios::app); if (fs_log.is_open()) { fs_log&lt;&lt;query.toUtf8().data()&lt;&lt;std::endl; } #endif result &amp;= queryObject.exec(query); #ifdef SQLDB_SHOW_QUERIES if (!result) std::cout&lt;&lt;queryObject.lastError().text().toStdString()&lt;&lt;std::endl; std::cout&lt;&lt;std::endl; #endif #ifdef SQLDB_LOG_QUERIES if (fs_log.is_open()) { if (!result) fs_log&lt;&lt;queryObject.lastError().text().toUtf8().data()&lt;&lt;std::endl; fs_log&lt;&lt;std::endl; fs_log.close(); } #endif return result; } // your sample code QSqlQuery myQuery(db); QString query = QString("INSERT INTO mytable VALUES (%1,%2)") .arg(1).arg(2); executeQuery(myQuery,query); </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.

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