maxdb_field_seek -- maxdb_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

bool maxdb_result::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
