I know how to read write data to an android SQL database, but i ran over a problem when i am trying to append data. When i do that it only appends Last record.

For data update i am using ` 

```
ContentValues updateKoment = new ContentValues();
            updateKoment.put("comment", text.getText().toString());
             db.update("MyTab",updateKoment, "PhoneNr='"+newn+"'AND Name='"+contact+"'AND comment='"+previuscom+"' AND Answered='"+Yn+"'",null);

```

It would be nice if you could help me and point me in the right direction.
