EXAMPLES

       Example #1

	      Object oriented style

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

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

	      /* Create table doesn't return a resultset */
	      if ($maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) {
		 printf("Table mycity successfully created.
");
	      }

	      /* Select queries return a resultset */
	      if ($result = $maxdb->query("SELECT name FROM hotel.city")) {
		 printf("Select returned %d rows.
", $result->num_rows);

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

	      /* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */
	      if ($result = $maxdb->query("SELECT * FROM hotel.city", MAXDB_USE_RESULT)) {
		 $result->close();
	      }

	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

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

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

	      /* Create table doesn't return a resultset */
	      if (maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) {
		 printf("Table mycity successfully created.
");
	      }

	      /* Select queries return a resultset */
	      if ($result = maxdb_query($link, "SELECT name FROM hotel.city")) {
		 printf("Select returned %d rows.
", maxdb_num_rows($result));

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

	      /* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */
	      if ($result = maxdb_query($link, "SELECT * FROM hotel.city", MAXDB_USE_RESULT)) {
		 maxdb_free_result($result);
	      }

	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Table mycity successfully created.
       Select returned 25 rows.

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.
