Question

All the examples I see for doing a query show only using one key. Is it possible to use two keys. I have tried the code below and it does not work. I am trying to find the row where date and time match the date and time in the table

    public String getPrimaryID(int date, int time )
{

    Cursor c= db.query(DB_TABLE, new String[]{KEY_ROWID}, "date="+date+ "time=" + time, null, null, null, null);
    int id=c.getColumnIndex(KEY_ROWID);
    String result=c.getString(id);
    return result;

}

I think you need to AND your query:

Cursor c= db.query(DB_TABLE, new String[]{KEY_ROWID}, "date="+date+ " AND time=" + time, null, null, null, null);
