范例

Example #1 Schema::dropCollection example

 <?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");

$session->sql("DROP DATABASE IF EXISTS food")->execute();
$session->sql("CREATE DATABASE food")->execute();
$session->sql("CREATE TABLE food.fruit(name text, rating text)")->execute();

$schema = $session->getSchema("food");

$schema->createCollection("trees");
$schema->dropCollection("trees");
$schema->createCollection("buildings");

print_r($schema->gettables());
print_r($schema->getcollections());

以上例程的输出类似于：

Array
(
    [fruit] => mysql_xdevapi\Table Object
        (
            [name] => fruit
        )
)
Array
(
    [buildings] => mysql_xdevapi\Collection Object
        (
            [name] => buildings
        )
)
