title: Howto execute a sql command inside transaction
body: <p>I am using OrientDb Version 2.0 M2 with PLocal connections.</p>
  
  <p>The javadoc of 
  <code>OCommandRequest com.tinkerpop.blueprints.impls.orient.OrientBaseGraph.command(OCommandRequest iCommand)</code>
  says
  "Executes commands against the graph. Commands are executed outside transaction."</p>
  
  <p>Now i am wondering, if it is possible to execute my SQL commands inside a transaction.</p>
