       int maxdb::field_count (void  )

       when using the maxdb_store_result(3) function to determine if the query should have produced a non-empty result set or not without  knowing

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      maxdb_report (MAXDB_REPORT_OFF);
	      $maxdb->query("DROP TABLE friends");
	      maxdb_report (MAXDB_REPORT_ERROR);

	      $maxdb->query( "CREATE TABLE friends (id int, name varchar(20))");

	      $maxdb->query( "INSERT INTO friends VALUES (1,'Hartmut')");
	      $maxdb->query( "INSERT INTO friends VALUES (2, 'Ulf')");

	      if ($maxdb->field_count()) {
		 /* this was a select/show or describe query */
		 $result = $maxdb->store_result();

		 /* process resultset */
		 $row = $result->fetch_row();

		 /* free resultset */
		 $result->close();
	      }

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      maxdb_report (MAXDB_REPORT_OFF);
	      maxdb_query($link,"DROP TABLE friends");
	      maxdb_report (MAXDB_REPORT_ERROR);

	      maxdb_query($link, "CREATE TABLE friends (id int, name varchar(20))");

	      maxdb_query($link, "INSERT INTO friends VALUES (1,'Hartmut')");
	      maxdb_query($link, "INSERT INTO friends VALUES (2, 'Ulf')");

	      if (maxdb_field_count($link)) {
		 /* this was a select/show or describe query */
		 $result = maxdb_store_result($link);

		 /* process resultset */
		 $row = maxdb_fetch_row($result);

		 /* free resultset */
		 maxdb_free_result($result);
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

	The above example produces no output.
