添加SQLite条目不在onCreate方法中

Question

The fact is that I am using SQLite to create a database which stores the puntuation of a game. I need a number, the puntuation, which will update when it must to. I created a class extending SQLiteOpenHelper, named MonedasSQLite.

But the database is empty yet. To introduce information, in the onCreate method of the Game.java class, I write this:

private MonedasSQLite base_monedas = new MonedasSQLite(this, "DBMonedas", null, 1);
base_monedas.insertarReg(0,0);
base_monedas.cerrar();

Where insertarReg is:

public void insertarReg(Integer cod, Integer mon) {
    ContentValues valores = new ContentValues();
    valores.put("codigo", cod);
    valores.put("money", mon);
    this.getWritableDatabase().insert("monedas", null, valores);
}

And cerrar() is just for closing:

public void cerrar() {
    this.close();
}

Doing so, everytime the user goes into the layout with the Game.java assigned, a new row of values (0,0) is being created. This way, when the user has entered 5 times there, the content of the database is (imagine the current puntuation is 100):

(0,100) (0,100) (0,100) (0,100) (0,0) --> As I am updating the (1st column=0 value) when the user does something OK, all the rows are updated. The last one not yet, because it has just been created.

What I am looking for is how can I create an entry of (0,0) out of the onCreate(), so that my database only has a row.

Hope somebody could help me! Hope too that I was clear in my explanation, if not please ask and I will write more code or information needed.

Thanks in advance!!!
