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();
...
