SQLITE Database in Project

goetz

the target path of your app is /usr/local/bin, the path of your db is test.sqlite - so the complete path is /usr/local/bin/test.sqlite. Sounds quite ok for me (in regard to the setup, a database file in /usr/local/bin is a no-go!).

Do you have a test.sqlite that actually is packed in your setup?

And be aware, the packing options are Symbian only!. It is ignored for any other operating systems, including Meego! It is for reason, that Matze5590 has put them into the symbian scope!

Its simply
QString dbName="test.sqlite";

Iam developing for meego in windows developement enviorment using Qt creator[/quote]

Try to use the absolute path. You can get the file path of the application executable using "QCoreApplication::applicationFilePath":http://doc.qt.nokia.com/latest/qcoreapplication.html#applicationFilePath

Hi Leon,
Thanks for the support ,
I have tried using the QCoreApplication::applicationFilePath
@QString dbName=QCoreApplication::applicationFilePath()+“\test.sqlite”;@
But it seems not opening the database.
All I wanted to pack the sqlite database inside my application so that i can install the applications as a single unit.

I think you should follow Volker's hint :) Please read "MeeGo Packaging/Guidelines":http://wiki.meego.com/Packaging/Guidelines As you probably know MeeGo apps are distributed as rpm so you have to include your database into the rpm.

some time , we need store a read-only database file in the QRC file. just need read no need change.
store in qrc file will avoid use change ,delete....etc it. and use database file (qsqlite3 ) will be fast get query result.

now qt version is 5.8. can we do it ?

best regards,

mrjj

Hi
If small database, you can just copy
it to file system upon run and
open it.

Just override it each time.

I do not think its possible to have a db in qrc.

cawlfj

@mrjj yes , you are right . we can do as your way. but i think if the db file in inside the qrc file will be more safety than copy out.
Some time , some data , we don't want some body to get it .

mrjj

@cawlfj
Well its not impossible to still dig it out using a hex editor.
For dbs, something like

might be better.
Maybe you can use the dump trick to upload to a :mem based db.

Consider using QTemporaryFile::createNativeFile:

QTemporaryFile *QTemporaryFile::createNativeFile(QFile &file)
QTemporaryFile *QTemporaryFile::createNativeFile(const QString &fileName)

then you can pass a resource path as fileName.
