maxdb_fetch_fields

Returns an array of resources representing the fields in a result set (PECL maxdb:1.0-7.6.00.38)
mixed maxdb_fetch_fields ( resource result )

Procedural Style:

Object oriented style (method):

result {
  mixed fetch_fields();
}

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.

Table 164. Object properties

PropertyDescription
nameThe name of the column
max_lengthThe maximum width of the field for the result set.
typeThe data type used for this field
decimalsThe number of decimals used (for integer fields)


Examples

Example 1196. 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 1197. 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
