Unsolved SQLite3 Insert function

[mandruk1331]

I'm trying to insert data into the SQLite3 database.
query.prepare("INSERT INTO lecturer (ID,LecturerName)"
"VALUES (ID, LecturerName);");
query.bindValue("::ID",ui->lineEdit->text().toInt());
query.bindValue("::LecturerName",ui->lineEdit_2->text());

ID is and INTEGER with AUTOINCREMENT
LecturerName is a char(50)
The connection to the database is established.
Error which I get when I want to insert the data into the database:
No query Unable ti fetch row
Can someoen help with this issue?? thank you

Hi
You have a ":" too much for the bindvalue it seems.
Also just so we are on the same page. a ("INSERT INTO"..) sql statement do not return
rows. Only a("SELECT X ") sql would. (AFAIK)

bool createConnection() {
  QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
  db.setDatabaseName(":memory:");
  if (!db.open()) {
    QMessageBox::critical(0, qApp->tr("Cannot open database"), "Click Cancel to exit.", QMessageBox::Cancel);
    return false;  }

  QSqlQuery query;
  qDebug() << "table:" <<   query.exec("create table person (id int primary key, "
                                       "firstname varchar(20), lastname varchar(20), num int )");
  query.exec("insert into person values(101, 'Dennis', 'Young','1')");
  query.exec("insert into person values(102, 'Christine', 'Holand','2')");
  query.exec("insert into person values(103, 'Lars junior', 'Gordon','4')");
  query.exec("insert into person values(104, 'Roberto', 'Robitaille','5')");
  query.exec("insert into person values(105, 'Maria', 'Papadopoulos','3')");
  return true;
}
    QSqlQuery query;
    int ok = query.prepare("SELECT firstname,num FROM person WHERE num=:thenum AND firstname=:thename AND lastname=:lastname");
    query.bindValue(":thenum", 4);
    query.bindValue(":thename", "Lars junior");
    query.bindValue(":lastname", "Gordon");
    query.exec();
