Pre populated database stuck in INIT and never opens

[cstehreem]

I am creating an update to my app which required significant changes in database and I created a new one. Now I am trying to migrate previous database's data to new one but my old database (injected into databases folder) is stuck in INIT state and never opens. If I try to open new database (created by the app) with same method in the same folder, it works just fine.

Here is my openDatabase call const databaseName = "food_cost_calculator_sqlite.db3"; const connection = SQLite.openDatabase( { name: databaseName, readOnly: true, createFromLocation: "/data/data/user/0/com.foodcostcalculator/databases/food_cost_calculator_sqlite.db3" }, successCallBack, errorCallBack );

If I swap food_cost_calculator_sqlite.db3 with FoodCostCalculator_DB.db it opens that database.

My app's file structure that I am monitoring through Android Device Monitor:

Can anyone help me with this? Or suggest an alternate way may be.

Thanks

ok I was able to open the database through the simple open call: const databaseName = "Food_Cost_Calculator_SQLite.db3"; const connection = SQLite.openDatabase( { name: databaseName, readonly: false, location: "Documents" }, successCallBack, errorCallBack );

And all my previously stored data is available there. Can anyone explain what is happening?

Thanks

Just a hint @cstehreem : you can use attachDatabase to attach the old database to the new one (or vice versa) for being able to just do things like "INSERT INTO newDatabase.myTable SELEC * FROM oldDatabase.myTable" and so on

Doesn't attach database also require an open instance of both databases? Also is there anything wrong with the way i am opening it now? Your help is much appreciated.

Yes, both databases must be opened before to get an sqlite-file-handle under the hood. Can't see any issues on the way you do the openDatabase. Should work

have a look at this example: https://github.com/andpor/react-native-sqlite-storage/#attaching-another-database

Yeah that's where the problem is. I am unable to open the second instance through the method for prepopulated database which is given in docs. But it's opening fine now so I guess I will just keep using that method unless someone can point out anything might go wrong with it. Thanks though.

You should debug the openDatabase under the hood with XCode or Android Studio, depending on the system that you are working on.

[cstehreem]

Okay I will try that.

opening database - review the API calls and read the comments. The paths are not absolute...they usually refer to subdirectories of well known directories...
