QT SQL DATABASE LOGIN
-
Hi,
That's the kind of constraints that should be done at the database level.
Your database structure might also be too simple in the sense that if can be pretty easy to get duplicated data with small typos. -
In any case, when a query goes wrong (if that's what's happening), use https://doc.qt.io/qt-5/qsqlquery.html#lastError to print out the text of the error.
Have you done this yet?

Well, in that case you should start by learning a bit more about them before going further. At least take the time to go through Qt's SQL module documentation and examples.
