mixed maxdb_fetch_fields (resource $result)
DESCRIPTION
Object oriented style
mixed maxdb_result::fetch_fields (void )
This function serves an identical purpose to the maxdb_fetch_field(3) 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

EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", 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
", $val->name);
printf("Table: %s
", $val->table);
printf("max. Len: %d
", $val->max_length);
printf("Flags: %d
", $val->flags);
printf("Type: %d
", $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
", 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
", $val->name);
printf("Table: %s
", $val->table);
printf("max. Len: %d
", $val->max_length);
printf("Flags: %d
", $val->flags);
printf("Type: %d
", $val->type);
}
maxdb_free_result($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
