Good idea @n-arakawa. 😄

I agree, this is especially a good idea since we already save all the other aspects regarding attached databases (like view and table settings) to the project file. It's just the path and name which are missing. So I have just added the required bits 😄 Can you check tomorrow's nightly build and re-save your project file after attaching the database(s), then load it again to see if it's working as expected now, @n-arakawa?

So easy 😄 I took a look and thought how to do it using our API but didn't find a way. Using the SQLite is straightforward, I see now. 👍

[MKleusberg]

Haha 😄 I was thinking that we should maybe add an equivalent for querySingeValueFromDb() someday to query multiple rows. That would offer a cleaner and more obvious API for cases like this one.

[mgrojo]

Yes, I meant something in our classes for getting the attached database, but you are right too.

Fine!
It's OK with commit b6d436d.
Thank you all for efforts.
