title: Difference between table access by index rowid BATCHED and table access by index rowid
body: <p>I'm using <code>EXPLAIN PLAN</code> in an Oracle database on a simple <code>SELECT</code> statement just to find out how it works.</p>
  <p>In one output of <code>EXPLAIN PLAN</code> there is mentioned <code>table access by index rowid</code> and in the other there is <code>table access by index rowid BATCHED</code>.</p>
  <p>What is the difference between them?</p>
