		is assumed.

RETURN VALUES

	Returns the error number from the last CUBRID function, or 0 (zero) if no error occurred.

EXAMPLES

       Example #1

	      cubrid_errno(3) example

	      <?php
	      $con = cubrid_connect('localhost', 33000, 'demodb', 'dba', '');
	      $req = cubrid_execute($con, "select id, name from person");
	      if ($req) {
		  while (list ($id, $name) = cubrid_fetch($req))
		  echo $id, $name;
	      } else {
		  echo "Error Code: ", cubrid_errno($con);
		  echo "Error Message: ", cubrid_error($con);
	      }
	      ?>
