QT Query SQL Lite Database - c++

Question

In our sql lite terminal when we type
SELECT * FROM Measures
we get everything from measure in the database called OMBI.db.
But now we want to connect the database via QT C++ GUI development platform. To do this we used the following code:
db = QSqlDatabase::addDatabase("QSQLITE");
db.setDatabaseName("/Desktop/project/src/OMBI.db");
bool db_ok = db.open();
qDebug() << db_ok;
QSqlQuery query;
//query.exec("SELECT * FROM Measures");
if(query.exec("SELECT * FROM Measures")){
while(query.next()){
qDebug() << query.value(0).toInt();
}
qDebug() << query.lastError().text();
qDebug() << "Inside First if Statement";
}
else
{
qDebug() << query.lastError().text();
}
Note that all our core code for the GUI project is placed under desktop/project/src and we've also placed OMBI.db database file inside there.
From other questions we were led to believe that if we have successfully opened the database, the line qDebug() << db_ok; would return true. Thinking that its been returning true, we thought our problem would be within the if statement where we query. But what we've found is that no matter what we set db.setDatabaseName("");, it will return true. What might our problem be? I am sure that we are not reading the database in correctly since if we type db.setDatabaseName("non_existent_random_file"); we still get true.
EDIT:
Also we keep getting the following error when we query:
"no such table: Measures Unable to execute statement"
Any ideas?

It will create the database if it doesn't exist. Probably your path is wrong. Shouldn't you have db.setDabaseName("/home/userName/Desktop/.....)?
