Hi everyone!

I'm trying to connect to a qsqlite database, so far I get an open connection (at least open() returns true), but when i check lastError() I get this:
Qt Code: 
  1. QSqlError(-1, "", "")

Queries return empty too. I've been googling my eyes out and can't find a solution (I don't even know what the problem is )

I'm using OS X 10.5.7 , QT 4.5.2 and QTCreator 1.2.
Here's the code:

Qt Code: 
  1. #include <QDebug>
  2. #include <QtSql>
  3.  
  4. int main(int argc, char *argv[])
  5. {
  6.     QApplication a(argc, argv);
  7.     QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
  8.  
  9.     //  db.setHostName("localhost");
  10.     // db.setDatabaseName("data.db");
  11.     db.setDatabaseName(":memory:");
  12.  
  13.     if (!db.open()) {       
  14.              qWarning("Can't open database");  
  15.  
  16.     } else {
  17.  
  18.        QSqlQuery query;
  19.        query.exec("create table person (id int primary key, "
  20.                "firstname varchar(20), lastname varchar(20))");
  21.        query.exec("insert into person values(101, 'Danny', 'Young')");
  22.        query.exec("insert into person values(102, 'Christine', 'Holand')");
  23.        query.exec("insert into person values(103, 'Lars', 'Gordon')");
  24.        query.exec("insert into person values(104, 'Roberto', 'Robitaille')");
  25.        query.exec("insert into person values(105, 'Maria', 'Papadopoulos')");
  26.  
  27.        QSqlQuery select;
  28.        select.exec("select * from person");
  29.        qDebug() << select.record().value(1).toString();
  30.  
  31.        qDebug() << db.lastError();
  32.        qDebug() << QSqlDatabase::drivers();[/INDENT]
  33.  
  34.     }
  35.  
  36.     Principal w;
  37.     w.show();
  38.  
  39.     return a.exec();
  40. }
