QUESTION
I use the library android-sqlite-asset-helper
It is necessary to update, but so that the user has saved data. The names of the tables, columns remained the same. Only the number of entries in the tables has increased.
I increased DATABASE_VERSION. Put the database in the archive. As stated in the instructions created file - brodsky.db_upgrade_1-2.sql
...ANSWER
Answered 2018-Dec-22 at 09:05From your code and assuming that the code is in the onUpgrade method and that the version was changed from 1 to 2 then the code does nothing of use. That is it :-
- renames the poems_table of the older database
- creates a new poems_table
- copies the contents of the renamed table to the newly created table
- deletes the renamed poems_table.
Nowhere does it access the newer version of the brodsky.db
What you need (I believe) to do is open that newer brodsky.db and copy the data from that database.
Working ExampleThe following is code for such a working example.
This will, when the Database version is increased (for simplicity any upgrade):-
- copy the new updated database as a separate/additional database and
- attempt to copy the rows from the updated database into the existing database
- only if they are not existing rows (based upon all columns except the id column as the end user may have added poems and thus used id's).
the core code is within PoemsDbHelper.java and is :-

QUESTION
For my unit tests I have collected real-world sensor data in a SQLite database. I need this data to create my tests. I tried the two methods below without success.
I am really stumped by this issue, because normally SQLiteOpenHelper loads any database in /data/data/packageName/databases/ flawlessly.

QUESTION
I have implemented a room database which is distributed from a resource file using SQLiteAssetHelper the first time the app is started.
The database contains game status data so if the Player wants to start all over again, I want to copy again the database file from the resource and overwrite the "local/internal" file.
So my idea was to delete the interal db-file so that SQLiteAssetHelper will copy the Initial database from the resource again.
Thank you!

QUESTION
I'm following this recommended guide to create a SQLite database with pre-loaded data; however I cannot understand how to produce the required database file (.db).
I have used the software "DB Browser for SQLite" to write up my database, but can only seem to save the file as the commands to create a database (CREATE TABLE IF NOT EXISTS etc.).
How do I save my file into the required .db format?
This website's solution is why I think my file is in the wrong format.
For context, the error I am experiencing is as follows:
...ANSWER
Answered 2017-Sep-02 at 22:42You can create a file just like a myfunc.js file or index.html but this one is mydb.sql with the codes. Regular word file ex:
CREATE DATABASE activedb;
CREATE TABLE table_name (
column1 datatype,
column2 datatype,
column3 datatype,
....
);
then you can use database_name < mydb.sql
I think that is what you are trying to do. I am not sure.
QUESTION
My RecyclerView was working fine when i populated it from a local database using SQLiteHelper, but now i want to populate it using an external database located in my assets folder by using SQLiteAssetHelper, so i followed the example from this Github SQLiteAssetHelper example but i think that the SimpleCursorAdapter() method is compatible ListView but not with the RecyclerView as it gives me an "Incompatible Type" IDE error.
Is their a way around this or should i convert my RecyclerView to a ListView? Help would be greatly appreciated.
