SQLITE selection with date not working on my QT project even following SQLite documentation..
-
Hello,
Using qt and js, I'm trying to make query like:
'SELECT rowid, registration, date_trip, time_used, total_time from trip_log where date_trip < ("2017-10-04") order by date_trip asc limit 1'but it's not working...
I did the same with registration and it's working, what is wrong with date?... I try to insert date_trip in TEXT, INT or REAL and no effect...
Thank you very much for you help

Maybe the trip was not so nice.. :)
I normally use a timestamp field (with date and time) and the queries are working perfectly.

- why are you not using SqlQueryModel?
- what is [Pdateinstallation]?

@VRonin I'm using this method because it's the first time I'm using SQLite with QT and I was the method used on example http://doc.qt.io/qt-5/qtquick-localstorage-example.html
[Pdateinstallation] is an arbitrary name used to be able to use many time the function on qml form with different date

Sorry, I missed the first line of your code.
did you try changingJS.potentieldated(2018-01-02)toJS.potentieldated('2018-01-02') -

the example is I'm doing heurecellule = tempsbloc + previous heurecellule when I insert new row.
But if I have to delete a row, I would like to make heurecellule - tempsbloc on all upper row from the deleted row

just connect a slot to
rowRemovedsignal of the model.You are doing a lot of logic on the QML side and it's really not advisable. You should consider moving the model functionality to c++
