for a single database table.</p>
<p>QSqlTableModel is a high-level interface for reading and writing database records from a single table. It is build on top of the lower-level <a href="qsqlquery.html">QSqlQuery</a> and can be used to provide data to view classes such as <a href="qtableview.html">QTableView</a>. For example:</p>
<pre>
QSqlTableModel *model = new QSqlTableModel;
model->setTable("employee");
model->setEditStrategy(QSqlTableModel.OnManualSubmit);
model->select();
model->removeColumn(0); // don't show the ID
model->setHeaderData(0, Qt.Horizontal, tr("Name"));
model->setHeaderData(1, Qt.Horizontal, tr("Salary"));
QTableView *view = new QTableView;
view->setModel(model);
view->show();
</pre>
<p>We set the SQL table's name and the edit strategy, then we set up the labels displayed in the view header. The edit strategy dictates when the changes done by the user in the view are actually applied to the database. The possible values are <a href="qsqltablemodel.html#EditStrategy-enum">OnFieldChange</a>, <a href="qsqltablemodel.html#EditStrategy-enum">OnRowChange</a>, and <a href="qsqltablemodel.html#EditStrategy-enum">OnManualSubmit</a>.</p>
<p>QSqlTableModel can also be used to access a database programmatically, without binding it to a view:</p>
<pre>
QSqlTableModel model;
model.setTable("employee");
QString name = model.record(4).value("name").toString();
</pre>
<p>The code snippet above extracts the <tt>salary</tt> field from record 4 in the result set of the query <tt>SELECT * from employee</tt>.</p>
<p>It is possible to set filters using <a href="qsqltablemodel.html#setFilter">setFilter</a>(), or modify the sort order using <a href="qsqltablemodel.html#setSort">setSort</a>(). At the end, you must call <a href="qsqltablemodel.html#select">select</a>() to populate the model with data.</p>
<p>The <a href="sql-tablemodel.html">sql/tablemodel</a> example illustrates how to use QSqlTableModel as the data source for a <a href="qtableview.html">QTableView</a>.</p>
<p>QSqlTableModel provides no direct support for foreign keys. Use the <a href="qsqlrelationaltablemodel.html">QSqlRelationalTableModel</a> and <a href="qsqlrelationaldelegate.html">QSqlRelationalDelegate</a> if you want to resolve foreign keys.</p>
<p>See also <a href="qsqlrelationaltablemodel.html">QSqlRelationalTableModel</a>, <a href="qsqlquery.html">QSqlQuery</a>, and <a href="model-view-programming.html">Model/View Programming</a>.</p>

<p>This is a low-level method that operates directly on the database and should not be called directly. Use <a href="qsqltablemodel.html#setData">setData</a>() to update values. The model will decide depending on its edit strategy when to modify the database.</p>
<p>Note that only values that have the generated-flag set are updated. The generated-flag can be set with <a href="qsqlrecord.html#setGenerated">QSqlRecord.setGenerated</a>() and tested with <a href="qsqlrecord.html#isGenerated">QSqlRecord.isGenerated</a>().</p>
