With this code in the constructor of my mainwindow:
db = QSqlDatabase::addDatabase("QSQLITE","localdb");
db.setDatabaseName("../test/test.db");
if (!db.open()) {
QMessageBox::critical(0, QObject::tr("Database Error"),
db.lastError().text());
}
model = new QSqlTableModel(this);
model->setTable("items");
model->select();
qDebug() << "SQL LastError:" << model->lastError().text();
and in the destructor:
db.close();
QSqlDatabase::removeDatabase("localdb");
delete ui;
output at start:
(I don’t have the qmessagebox and my table view stay blank.)
SQL LastError: “ Unable to find table items”
output at close app:
QSqlDatabasePrivate::removeDatabase: connection ‘localdb’ is still in use, all queries will cease to work.
If I remove the name of the connection, “localdb” and let the system use the default name, I have this:
db = QSqlDatabase::addDatabase("QSQLITE");
SQL LastError: “ “
and I have my datas shown in the table view… ?!?!?
No error at close.
What am I doing wrong with the connection name?
I need it because this app will have 2 separates connections, one local with sqlite and another to a remote db2 server.
