Question

I am trying to update a specific row that uses auto_increment as a primary key. Basically, I initialize the table in one activity and I want to complete the table on another. So, I use the update feature to do it. However, when I log to see how many rows where affected I get 0 back.
Here is my code:

public void updateValue(String updatedValue){
String strFilter = " (" + primaryKey + "== "+ "(SELECT last_insert_rowid())" + ")";
    ContentValues values = new ContentValues();
    values.put(val, updatedValue);
    db = this.getWritableDatabase();

    int rows= db.update(myTable, values, strFilter, null);
    Log.d(LOG_TAG, "The change has affected " + rows
            + " rows.");
    db.close();

}

I think that the problem in the following line:

String strFilter = " (" + primaryKey + "== "+ "(SELECT last_insert_rowid())" + ")";

It should be written, I guess, in the following way:

String strFilter = primaryKey + "=" + "(SELECT last_insert_rowid())";

But you should control the return of this part (SELECT last_insert_rowid()) if it returns last inserted row or not.
