/*AND

What is this?
Also use http://doc.qt.io/qt-5/qsqlquery.html#lastError to see what the error was.

@JonB
help me please

[JonB]

@123456789
Both I & @jsulm have indeed told you what you need to do/read up. In a forum like this you need to put some effort in yourself, nobody wants to keep writing your complete code for you, we have our own work to do too....

[123456789]

Where?
Not result
QSqlQuery qry;
if(qry.exec("SELECT User, Password, Role FROM Users Where User='" + Username +
"' Password='" + Password + "' /* Role='" + Rol1 + "'" ))
{

@123456789 When qry.exec() fails I would assume...

[123456789]

what @jsulm

[JonB]

@123456789

if (qry.exec(...)) {
   ...
} else {
  qDebug() << qry.lastError();
}

qDebug(qry.lastError());

qDebug() << qry.lastError();
