QSqlQuery not working - c++

Question

So I have this problem basically, I cannot exec my QsqlQuery.
I am connected to a SQLite database and I have checked that it is really connected.
QString databaseName = QFileDialog::getOpenFileName(this,tr("Open database"),
"",
tr("Databáze (*.db)"));
mydb = QSqlDatabase::addDatabase("QSQLITE");
mydb.setDatabaseName("databaseName");
if (!mydb.open()) {
ui->statusBar->showMessage("Databáze nebyla připojena!",2000);
databaseCheck = false;
}
else if (mydb.open()) {
ui->statusBar->showMessage("Databáze byla úspěšně připojena.",2000);
databaseCheck = true;
}
This is part of the code from the Mainwindow.cpp which sets up the database connection. The database is declared in mainwindow.h, all is functioning in this part.
Here I got a form which returns some data about an employee that I want to create in the database. databaseCheck is a bool that tells me if the database is connected properly. And those variables name, surname etc. in this case are declared in mainwindow.h as QString.
if (databaseCheck) {
form = new Form(this);
form->setWindowTitle("Formulář informací o zaměstnanci.");
form->exec();
name = form->getName();
surname = form->getSurname();
id = form->getId();
date = form->getDate();
telephone = form->getTelephone();
salary = form->getSalary();
state = form->getState();
QSqlQuery query(mydb);
query.prepare("INSERT INTO employees (jmeno,prijmeni,datumnarozeni,telefon,plat,stav) "
"VALUES (:name, :surname, :date, :telephone, :salary , :state)");
query.bindValue(":name", name);
query.bindValue(":forename", surname);
query.bindValue(":date", date );
query.bindValue(":telephone", telephone);
query.bindValue(":salary", salary);
query.bindValue(":state", state );
query.exec();
}
After I fill up the form with some data about the employee and accept it, it does not send anything to the database. I am checking the database with DB Browser for SQLite and the table employees is totally empty. Can anybody help me?

Your SQL seems correct, the best approach is probably to write something like this.
if (!query.exec())
qDebug() << query.lastError();
