SQLite database

[Verminoz]

Hello,
I have an application that wants to read/write data from an SQLite database. I load the database but it does not really load it. I cannot read any data from it with a query and it returns a zero number of tables. The code is

@
// Setup database
db = QSqlDatabase::addDatabase("QSQLITE");
db.setHostName("/home/verminoz/mybase.db");
db.setDatabaseName("main");

bool ok = db.open();
if (!ok)
{
    QMessageBox::critical(this, tr("database error"),tr("Could not open database! Make sure your database exists!"),QMessageBox::Ok);
}
qDebug() << db.tables().count() << endl;

@

The driver is available and open() returns true. Any ideas?

Thank you in advance

Hi,

In my opinion you should remove if your database is on the same computer:
@db.setHostName("/home/verminoz/mybase.db");@

It seems that you are using Linux but anyway it is better to make your code platform independent. Try something like this:

@
db = QSqlDatabase::addDatabase("QSQLITE");
#ifdef Q_OS_LINUX
QString path(QDir::home().path());
path.append(QDir::separator()).append("mybase.db");
path = QDir::toNativeSeparators(path);
db.setDatabaseName(path);
#else
db.setDatabaseName("mybase.db");
#endif

bool ok = db.open();
if (!ok)
{
QMessageBox::critical(this, tr("database error"),tr("Could not open database! Make sure your database exists!"),QMessageBox::Ok);
}
qDebug() << db.tables().count() << endl;
