title: pdo execute multiple queries
body: <p>I need to run an insert and a simultaneous update, but I'm using only insert test to catch errors.<br><br>
  The PDO does not report the error when I define a correct and an incorrect table, but if I run a query to select one incorrect table the error is reported.<br><br>
  I do not have enough knowledge to solve this problem, i really need to execute two queries together
  Thank you.<br><br></p>
  
  <pre><code>$db-&gt; setAttribute( PDO::ATTR_ERRMODE , PDO::ERRMODE_EXCEPTION );
  
  try{
      $stmt = $db-&gt; prepare( "INSERT INTO test ( name ) values( 'new name' );
                              INSERT INTO xast ( xame ) values( 'new name' );" );
      $stmt-&gt;execute();
  }catch( PDOException $e ){
      print_r( $e );
  }
  
  
  try{
      $stmt = $db-&gt; prepare( "INSERT INTO xast ( xame ) values( 'new name' );" );
      $stmt-&gt;execute();
  }catch( PDOException $e ){
      print_r( $e );
  }
  **Column not found: 1054 Unknown column 'xame'**
