||
|
|
|
||
|
|
The QSqlSelectCursor class provides browsing of general SQL
|
||
|
|
SELECT statements.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> QSqlSelectCursor is a convenience class that makes it possible to
|
||
|
|
display result sets from general SQL <tt>SELECT</tt> statements in
|
||
|
|
data-aware Qt widgets. QSqlSelectCursor 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="qsqlquery.html#exec">QSqlSelectCursor::exec</a>() function.
|
||
|
|
<p> Example:
|
||
|
|
<pre>
|
||
|
|
...
|
||
|
|
QSqlSelectCursor* cur = new QSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
|
||
|
|
<a href="qdatatable.html">QDataTable</a>* table = new <a href="qdatatable.html">QDataTable</a>( this );
|
||
|
|
table-><a href="qdatatable.html#setSqlCursor">setSqlCursor</a>( cur, TRUE, TRUE );
|
||
|
|
table-><a href="qdatatable.html#refresh">refresh</a>();
|
||
|
|
...
|
||
|
|
cur-><a href="qsqlquery.html#exec">exec</a>( "SELECT * FROM books" );
|
||
|
|
table-><a href="qdatatable.html#refresh">refresh</a>();
|
||
|
|
...
|
||
|
|
</pre>
