The TQSqlSelectCursor class provides browsing of general SQL
SELECT statements.
<p>
<p> TQSqlSelectCursor is a convenience class that makes it possible to
display result sets from general SQL <tt>SELECT</tt> statements in
data-aware TQt widgets. TQSqlSelectCursor is read-only and does not
support <tt>INSERT</tt>, <tt>UPDATE</tt> or <tt>DELETE</tt> operations.
<p> Pass the query in at construction time, or use the
<a href="ntqsqlquery.html#exec">TQSqlSelectCursor::exec</a>() function.
<p> Example:
<pre>
...
TQSqlSelectCursor* cur = new TQSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
<a href="ntqdatatable.html">TQDataTable</a>* table = new <a href="ntqdatatable.html">TQDataTable</a>( this );
table-&gt;<a href="ntqdatatable.html#setSqlCursor">setSqlCursor</a>( cur, TRUE, TRUE );
table-&gt;<a href="ntqdatatable.html#refresh">refresh</a>();
...
cur-&gt;<a href="ntqsqlquery.html#exec">exec</a>( "SELECT * FROM books" );
table-&gt;<a href="ntqdatatable.html#refresh">refresh</a>();
...
</pre>
