ORMLite update of the database

Question

I\'m actually developing an app which is using ORMLite library (which is wonderful btw) but I\'m a beginner using it.

I have a question about the update of the datab

Answer 1

I do it this way:

@Override
public void onUpgrade(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion) {

    switch (oldVersion) {
    case 1:
        updateFromVersion1(database, connectionSource, oldVersion, newVersion);
        break;
    case 2:
        updateFromVersion2(database, connectionSource, oldVersion, newVersion);
        break;
    default:
        // no updates needed
        break;
    }

}

private void updateFromVersion1(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion) {
    // do some stuff here
    onUpgrade(database, connectionSource, oldVersion + 1, newVersion);
}

private void updateFromVersion2(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion) {
    // do some stuff here
    onUpgrade(database, connectionSource, oldVersion + 1, newVersion);
}

This will incrementally update the users db independent from which db version he is coming.
