Example

Пример 1. Object oriented style

<?

$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();

?>

Пример 2. Procedural style

<?

$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);

?>
