QODBC Driver not loaded after successfull connection and query

Hello everbody,

i have a strange situation/behaviour with the QODBC driver.

I've deployed the application with all the release-libraries (Windows 7 x32).
When i do a simple QSqlDatabase connect with the QODBC driver, everything works well, including a QSqlQuery task.

Code:

---

QSqlDatabase myDb = QSqlDatabase::addDatabase("QODBC", "myDb123");
myDb.setDatabaseName("my odbc connection string");
if (!myDb.open()) {
  qDebug() << myDb.lastError().text();
}
// do query and other funny things like int omg = 12/0;

---

But .. when i do the exact same thing a second time at runtime, i get a "DRIVER NOT LOADED. DRIVER NOT LOADED." error.

When i restart the application i get the excat behaviour again: SUCCESS; then FAIL; FAIL; FAIL...

To be honest i dont really know how to isolate the problem.
Anyone has an idea why this might occur?

Try this:

Code:

---

if ( ! db.isOpen() )
{
   if ( ! db.open() ) 
   {
       qWarning();
   }
}

---

Thank you for your answer,
but nevermind... i found the problem.
The second QSqlDatabase instance was created with the same **:mad:** connectionName.
I have no idea how this could result in an error like "Driver not loaded" but hey it's working now.'
yay!
