<h2>Detailed Description</h2>

<p>The Q3SqlSelectCursor class provides browsing of general SQL SELECT statements.</p>

<p>Q3SqlSelectCursor is a convenience class that makes it possible to display result sets from general SQL <tt>SELECT</tt> statements in data-aware Qt widgets. Q3SqlSelectCursor is read-only and does not support <tt>INSERT</tt>, <tt>UPDATE</tt> or <tt>DELETE</tt> operations.</p>

<p>Pass the query in at construction time, or use the <a href="q3sqlselectcursor.html#exec">Q3SqlSelectCursor::exec</a>() function.</p>

<p>Example:</p>

<pre>  ...

Q3SqlSelectCursor* cur = new Q3SqlSelectCursor("SELECT id, firstname, lastname FROM author");

Q3DataTable* table = new Q3DataTable(this);

table->setSqlCursor(cur, true, true);

table->refresh();

...

cur->exec("SELECT * FROM books");

table->refresh();

...</pre>
