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 name";

if ($result = $maxdb->query($query)) {

   /* Get field information for column 'SurfaceArea' */
   $finfo = $result->fetch_field_direct(1);

   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", $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 name";

if ($result = maxdb_query($link, $query)) {

   /* Get field information for column 'cno' */
   $finfo = maxdb_fetch_field_direct($result, 1);

   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", $finfo->type);

   maxdb_free_result($result);
}

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

The above example will output something similar to:

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