MAXDB_CHANGE_USER(3)							 1						      MAXDB_CHANGE_USER(3)

maxdb_change_user - Changes the user of the specified database connection

       Procedural style

SYNOPSIS

       bool maxdb_change_user (resource  $link, string	$user, string  $password, string  $database)

DESCRIPTION

       Object oriented style
       bool maxdb::change_user (string	$user, string  $password, string  $database)

       maxdb_change_user(3) is used to change the user of the specified database connection as given by the $link parameter and to set the current
       database to that specified by the $database parameter.

	In order to successfully change users a valid $username and $password parameters must be provided and that user must have sufficient  per-
       missions to access the desired database. If for any reason authorization fails, the current user authentication will remain.

       Note

	       Using  this  command  will  always  cause the current database connection to behave as if was a completely new database connection,
	      regardless of if the operation was completed successfully. This reset includes performing a rollback  on	any  active  transactions,
	      closing all temporary tables, and unlocking all locked tables.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php

	      /* connect database test */
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

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

	      if ($result = $maxdb->query("SELECT * FROM dual")) {
		 $row = $result->fetch_row();
		 printf("Result: %s
", $row[0]);
		 $result->free();
	      }

	      /* reset all and select a new database */
	      if (!$maxdb->change_user("DBADMIN", "SECRET", "DEMODB")) {
		printf("Database not running
");
	      } else {
		printf("Database running
");
	      }

	      /* 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();
	      }

	      if ($result = maxdb_query($link, "SELECT * FROM dual")) {
		 $row = maxdb_fetch_row($result);
		 printf("Result: %s
", $row[0]);
		 maxdb_free_result($result);
	      }

	      /* reset all and select a new database */
	      if (!maxdb_change_user($link, "DBADMIN", "SECRET", "DEMODB")) {
		printf("Database not running
");
	      } else {
		printf("Database running
");
	      }

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

       The above example will output something similar to:

       Result: a
       Database running

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
