result->field_seek — Set result pointer to a specified field offset

Description

Procedural style:

bool maxdb_field_seek ( resource $result , int $fieldnr )

Object oriented style (method):

result

bool field_seek ( int $fieldnr )

Sets the field cursor to the given offset. The next call to maxdb_fetch_field() will retrieve the field definition of the column associated with that offset.

Note: To seek to the beginning of a row, pass an offset value of zero.

Return Values

maxdb_field_seek() returns previuos value of field cursor.

Examples

Example #1 Object oriented style


<?php

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



/* check connection */

if (maxdb_connect_errno()) {

   printf("Connect failed: %s\n", maxdb_connect_error());

   exit();

}



$query = "SELECT name, cno from hotel.customer ORDER BY cno";



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



   /* Get field information for 2nd column */

   $result->field_seek(1);

   $finfo = $result->fetch_field();



   printf("Name:     %s\n", $finfo->name);

   printf("Table:    %s\n", $finfo->table);

   printf("max. Len: %d\n", $finfo->max_length);

   printf("Flags:    %d\n", $finfo->flags);

   printf("Type:     %d\n\n", $finfo->type);



   $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\n", maxdb_connect_error());

   exit();

}



$query = "SELECT name, cno from hotel.customer ORDER BY cno";



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



   /* Get field information for 2nd column */

   maxdb_field_seek($result, 1);

   $finfo = maxdb_fetch_field($result);



   printf("Name:     %s\n", $finfo->name);

   printf("Table:    %s\n", $finfo->table);

   printf("max. Len: %d\n", $finfo->max_length);

   printf("Flags:    %d\n", $finfo->flags);

   printf("Type:     %d\n\n", $finfo->type);



   maxdb_free_result($result);

}



/* close connection */

maxdb_close($link);

?>

The above example will output something similar to:

Name:     NAME
Table:
max. Len: 10
Flags:    -1
Type:     2
