       Procedural style

SYNOPSIS

       bool maxdb_data_seek (resource  $result, int  $offset)

DESCRIPTION

       Object oriented style
       bool maxdb_result::data_seek (int  $offset)

	The  maxdb_data_seek(3)  function  seeks to an arbitrary result pointer specified by the $offset in the result set represented by $result.
       The $offset parameter must be between zero and the total number of rows minus one (0..maxdb_num_rows(3) - 1).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

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();
	      }

	      $query = "SELECT name, state FROM hotel.city ORDER BY name";
	      if ($result = $maxdb->query( $query)) {

		 /* seek to row no. 10 */
		 $result->data_seek(10);

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

		 printf ("City: %s  State: %s
", $row[0], $row[1]);

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

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

       Example #2

	      Procedural style

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

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

	      $query = "SELECT name, state FROM hotel.city ORDER BY name";

	      if ($result = maxdb_query($link, $query)) {

		 /* seek to row no. 400 */
		 maxdb_data_seek($result, 10);

		 /* fetch row */
		 $row = maxdb_fetch_row($result);

		 printf ("City: %s  State: %s
", $row[0], $row[1]);

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

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

       The above example will output something similar to:

       City: Irvine  State: CA

EXAMPLES

       Example #1

	      Object oriented style

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

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

	      /* return name of current default database */
	      if ($result = $maxdb->query("SELECT SERVERDB FROM USERS WHERE USERNAME='MONA'")) {
		 $row = $result->fetch_row();
		 printf("Default database is %s.
", $row[0]);
		 $result->close();
	      }

	      /* change db to non existing db */
	      $maxdb->select_db("XXXXXXXX");

	      /* return name of current default database */
	      if ($result = $maxdb->query("SELECT SERVERDB FROM USERS WHERE USERNAME='MONA'")) {
		 $row = $result->fetch_row();
		 printf("Default database is %s.
", $row[0]);
		 $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();
	      }

	      /* return name of current default database */
	      if ($result = maxdb_query($link, "SELECT SERVERDB FROM USERS WHERE USERNAME='MONA'")) {
		 $row = maxdb_fetch_row($result);
		 printf("Default database is %s.
", $row[0]);
		 maxdb_free_result($result);
	      }

	      /* change db to non existing db */
	      maxdb_select_db($link, "XXXXXXXX");

	      /* return name of current default database */
	      if ($result = maxdb_query($link, "SELECT SERVERDB FROM USERS WHERE USERNAME='MONA'")) {
		 $row = maxdb_fetch_row($result);
		 printf("Default database is %s.
", $row[0]);
		 maxdb_free_result($result);
	      }

	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Default database is <...>.

       Warning: maxdb_select_db(): -10709 Connection failed (RTE:database not running) <...>

       Warning: maxdb_query(): -10821 Session not connected [] <...>
