maxdb_fetch_fields -- result->fetch_fields — Returns an array of resources representing the fields in a result set

Description

Procedural Style:

mixed maxdb_fetch_fields ( resource $result )

Object oriented style (method):

result

mixed fetch_fields ( void )

This function serves an identical purpose to the maxdb_fetch_field() function with the single difference that, instead of returning one resource at a time for each field, the columns are returned as an array of resources.

Return Values

Returns an array of resources which contains field definition informations or FALSE if no field information is available.

Object properties

Property Description

name The name of the column

max_length The maximum width of the field for the result set.

type The data type used for this field

decimals The number of decimals used (for integer fields)

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 all columns */
   $finfo = $result->fetch_fields();

   foreach ($finfo as $val) {
       printf("Name:     %s\n", $val->name);
       printf("Table:    %s\n", $val->table);
       printf("max. Len: %d\n", $val->max_length);
       printf("Flags:    %d\n", $val->flags);
       printf("Type:     %d\n\n", $val->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 all columns */
   $finfo = maxdb_fetch_fields($result);

   foreach ($finfo as $val) {
       printf("Name:     %s\n", $val->name);
       printf("Table:    %s\n", $val->table);
       printf("max. Len: %d\n", $val->max_length);
       printf("Flags:    %d\n", $val->flags);
       printf("Type:     %d\n\n", $val->type);
   }
   maxdb_free_result($result);
}

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

The above example will output something similar to:

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

Name:     CNO
Table:
max. Len: 4
Flags:    -1
Type:     0
