Native driver doesn't complain when db file doesn't exist, and queries don't return anything

See original GitHub issue

Runtime Environment SQLDelight version: 1.4.0 Application OS: MacosX64

Created a Multiplatform project following the instructions here, and have a simple query, both on JVM (JdbcSqliteDriver) and native (NativeSqliteDriver) (please see sample project attached).

On the JVM when the .db the file is present, the query works and displays

Hello, World!
Activity_log [
  id: 1
  type: 0
  year: 2018
  month: 10
  day: 1
  hour: 9
  minute: 30
]

On MacOS, whether the .db file is here or not, the query doesn’t return anything:

$ ./gradlew build
$ ./build/bin/macosX64/debugExecutable/workinghour2.kexe
Hello, World!
null

Shouldn’t there be an error message when the db file cannot be opened?

Also I was wondering if there’s a way to enable some logs? Right now I find it difficult evaluating where the problem could lie.

Here’s the project in question: sqldelightnativeproblem.zip

@BoD Ok, thanks for your feedback.

Here is the solution to configure it: https://github.com/cashapp/sqldelight/issues/1787

I fiddled a bit around with that and indeed I have in no place I wanted it write/read permissions and would need to ask the user. 😕

I believe there is an option to save in ~/Library/Containers/<yourappname>/ without asking for permission because Sentry does put it’s logs here, but I also ran into issues with that.

So I guess I will solve this on another day as I already invested too much time here.

Hi @AshStefanOltmann in the end the default file location was good enough for my use-case. Also on MacOS there may be (not 100% sure) a permission to ask when trying to write files elsewhere.
