What is The use of moveToFirst () in SQLite Cursors

Question

I am a programming newbie and I found this piece of code in the internet and it works fine

Cursor c=db.query(DataBase.TB_NAME, new String[] {DataBase.KEY_ROW         


        

Answer 1

if (c.moveToFirst()) {
  while(!c.isAfterLast()) { // If you use c.moveToNext() here, you will bypass the first row, which is WRONG
    ...
    c.moveToNext();
  } 
}
