Best practices for working with multiple tables

Question

I use a database with multiple tables in my application. I have an XML parser which needs to write data to two tables while parsing. I created two database adapters for both tab

Answer 1

I'm a bit late maybe but i always open my database, not my table. So this form me as no sense.

    firstTable.open();
    secondTable.open(); 

Rather do this.

    dataBase.getWritableDatabase();

then if you want to update juste chose the table:

public int updateTotal (int id, Jours jour){
    ContentValues values = new ContentValues();

    values.put(COL_TOTAL,Total );

    //update the table you want
    return bdd.update(TABLE_NAME, values, COL_JOUR + " = " + id, null);
}

And that's all. Hope it can help other people
