问题:

Is it possible with OrmLite to create a sql script file to easily populate the database with data? I did some searching and couldn't come up with anything easy. I know I can create some objects with data, I'm just looking for a cleaner method.

I'm thinking create a script file, open a a reader at load, and process each file as raw SQL the executeRaw() method. Any thoughts?

Good one Joe. I think your idea of the executeRaw() is close but use updateRaw() instead. Update handles INSERT, DELETE, and UPDATE statements.

You should call TableUtils to create your schema first of course:

Hope this helps. You may want to use the mailing list for questions in the future:

Just wanted to post my solution for anyone who might need it

try {
    tableDAO.updateRaw("DELETE FROM table");
    InputStream is = getResources().openRawResource(R.raw.populate_db);
    DataInputStream in = new DataInputStream(is);
    BufferedReader br = new BufferedReader(new InputStreamReader(in));
    String strLine;
    while ((strLine = br.readLine()) != null) {
        tableDAO.updateRaw(strLine);
    }
    in.close();
} catch (Exception e) {
    e.printStackTrace();
}
