cannot open include file qsqldatabase

[Saurian]

Yes, run qmake after changing the PRO file.

Thanks. It works.

Your "quite simple" code is also unlikely to work when it compiles. A MySQL Workbench file is not a MySQL database.

Thanks. I'm a little new in working with Qt and MySQL. I'll work with the console to create my database. Is there a way to find out in which file the database created is saved?

just a note, dont you need a connection string or a dsn to open the connection with a database ?
something like :

QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
QString servername = "X-PC\\LOCALHOST";
QString dbname = "CARSQL";
QString connTemplate = "DRIVER={SQL SERVER};SERVER=%1;DATABASE=%2;";
QString connectionString = connTemplate.arg(servername).arg(dbname);
db.setDatabaseName(connectionString);

QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
QString servername = "X-PC\\LOCALHOST";
QString dbname = "CARSQL";
QString connTemplate = "DRIVER={SQL SERVER};SERVER=%1;DATABASE=%2;";
QString connectionString = connTemplate.arg(servername).arg(dbname);
db.setDatabaseName(connectionString);

or

QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL");
db.setHostName("acidalia");
db.setDatabaseName("customdb");
db.setUserName("mojito");
db.setPassword("J0a1m8");

QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL");
db.setHostName("acidalia");
db.setDatabaseName("customdb");
db.setUserName("mojito");
db.setPassword("J0a1m8");

Well I'm working on localhost and with no password or specific user name. I thought qt will implicit put localhost, root and no password. I have another question: How do you specify to which file the app should connect?
