## Detailed Description

The QSqlSelectCursor class provides browsing of general SQL SELECT statements.

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

Pass the query in at construction time, or use the QSqlSelectCursor::exec() function.

Example:

        ...
        QSqlSelectCursor* cur = new QSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
        QDataTable* table = new QDataTable( this );
        table->setSqlCursor( cur, TRUE, TRUE );
        table->refresh();
        ...
        cur->exec( "SELECT * FROM books" );
        table->refresh();
        ...
