Can't write into database

[artwaw]

@Babs Ok. So now you can test db.open() - it returns a value. On false, error should be present in lastError().

[Babs]

@artwaw it returns false and the error driver not loaded. I do the verification:

        if(!db.isOpen()){
            db.open();
            qDebug()<<db.lastError().text();
        }

[artwaw]

@Babs Are you completely sure that addDatabase() has been called at any point before call do QSqlDatabase::database()?
You could also test if driver is available by using QSqlDatabase::drivers() and other methods described in documentation.

[Babs]

@artwaw do i have to specify the connectionName when calling database() function?. Add data base in called in my main function before creation my engine.

[Babs]

@artwaw the driver for SQLite is indeed present.

[artwaw]

@Babs can you post your .pro files please?

[Babs]

@artwaw i'm working with QBS. When i don't specify the connectionName in addDataBase() function it open. I have the error "number of parameters incorrect". I think i don't have the good parameter types. I defined a QString as a TEXT is SQLite. Is it correct?

[Babs]

@artwaw here is my QBS file

@Babs ups. I have literally zero experience with qbs...
I am afraid you'll have to wait for someone who knows something about it, I am sorry.

[Babs]

I resolved my problem. I made an error in the type an name of one of the parameters. Thanks for your help @artwaw.

[artwaw]

@Babs Anytime.
Please don't forget to mark the thread as "solved".
