maxdb_data_seek - Adjusts the result pointer to an arbitary row in the result

       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

MAXDB_FETCH_LENGTHS(3)							 1						    MAXDB_FETCH_LENGTHS(3)

maxdb_fetch_lengths - Returns the lengths of the columns of the current row in the result set

       Procedural style

SYNOPSIS

       array maxdb_fetch_lengths (resource  $result)

DESCRIPTION

       Object oriented style
       array$maxdb_result->lengths ()

	The  maxdb_fetch_lengths(3) function returns an array containing the lengths of every column of the current row within the result set rep-
       resented by the $result parameter. If successful, a numerically indexed array representing the lengths of each column is returned or  FALSE
       on failure.

RETURN VALUES

	An array of integers representing the size of each column (not including any terminating null characters).  FALSE if an error occurred.

       maxdb_fetch_lengths(3)  is  valid  only	for  the  current  row	of  the  result  set.  It  returns  FALSE  if  you  call it before calling
       maxdb_fetch_row/array/resource or after retrieving all rows in the result.

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();
	      }

	      $query = "SELECT * from hotel.customer WHERE cno = 3000";

	      if ($result = $maxdb->query($query)) {

		 $row = $result->fetch_row();

		 /* display column lengths */
		 foreach ($result->lengths as $i => $val) {
		     printf("Field %2d has Length %2d
", $i+1, $val);
		 }
		 $result->close();
	      }

	      /* close connection */
	      $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();
	      }

	      $query = "SELECT * from hotel.customer WHERE cno = 3000";

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

		 $row = maxdb_fetch_row($result);

		 /* display column lengths */
		 foreach (maxdb_fetch_lengths($result) as $i => $val) {
		     printf("Field %2d has Length %2d
", $i+1, $val);
		 }
		 maxdb_free_result($result);
	      }

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

       The above example will output something similar to:

       Field  1 has Length  4
       Field  2 has Length  3
       Field  3 has Length  5
       Field  4 has Length  6
       Field  5 has Length  5
       Field  6 has Length 21
