how to get a column value from sql query?

Hi, has anyone know how to get a column's value from sql query? 

Here is my code, the value should be 1350079224397 in my db, but I get 0 

 

QString query("SELECT version FROM db_version");

QVariant result = sda.execute(query);
QVariantMap versionMap = result.toList().first().toMap();
if(!versionMap.isEmpty())
{
qDebug()<<"Version: " <<versionMap.value("version").toLongLong();
}
