EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Open a connection */
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
	      $maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city");

	      $query = "SELECT name, zip FROM temp.mycity ORDER BY name";
	      if ($stmt = $maxdb->prepare($query)) {

		 /* drop table */
		 $maxdb->query("DROP TABLE temp.mycity");

		 /* execute query */
		 $stmt->execute();

		 printf("Error: %d.
", $stmt->errno);

		 /* close statement */
		 $stmt->close();
	      }

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

       Example #2

	      Procedural style

	      <?php
	      /* Open a connection */
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
	      maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");

	      $query = "SELECT name, zip FROM temp.mycity ORDER BY name";
	      if ($stmt = maxdb_prepare($link, $query)) {

		 /* drop table */
		 maxdb_query($link, "DROP TABLE temp.mycity");

		 /* execute query */
		 maxdb_stmt_execute($stmt);

		 printf("Error: %d.
", maxdb_stmt_errno($stmt));

		 /* close statement */
		 maxdb_stmt_close($stmt);
	      }

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

       The above example will output something similar to:

       Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...>
       Error: -4004.

       Example #2

	      Procedural style

	      /* disable autocommit */
	      maxdb_autocommit($link, FALSE);

	      maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
	      maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");

	      /* commit insert */
	      maxdb_commit($link);

	      /* delete all rows */
	      maxdb_query($link, "DELETE FROM temp.mycity");

	      if ($result = maxdb_query($link, "SELECT COUNT(*) FROM temp.mycity")) {
		 $row = maxdb_fetch_row($result);
		 printf("%d rows in table mycity.
", $row[0]);
		 /* Free result */
		 maxdb_free_result($result);
	      }

	      /* Rollback */
	      maxdb_rollback($link);

	      if ($result = maxdb_query($link, "SELECT COUNT(*) FROM temp.mycity")) {

	      /* Drop table myCity */
	      maxdb_query($link, "DROP TABLE temp.mycity");

	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       0 rows in table mycity.
       25 rows in table mycity (after rollback).
