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 */
   while ($finfo = $result->fetch_field()) {

       /* get fieldpointer offset */
       $currentfield = $result->current_field;

       printf("Column    %d:\n", $currentfield);
       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 all fields */
   while ($finfo = maxdb_fetch_field($result)) {

       /* get fieldpointer offset */
       $currentfield = maxdb_field_tell($result);

       printf("Column    %d:\n", $currentfield);
       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:

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

Column    2:
Name:     CNO
Table:
max. Len: 4
Flags:    -1
Type:     0
