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.

Таблица 1. 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)

Example

Пример 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();
?>

Пример 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 examples would produce the following output:

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

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

Пред.	Начало	След.
maxdb_fetch_field	Уровень выше	maxdb_fetch_lengths
