示例 #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());以上示例的输出类似于：
Array
(
[fruit] => mysql_xdevapi\Table Object
(
[name] => fruit
)
)
Array
(
[buildings] => mysql_xdevapi\Collection Object
(
[name] => buildings
)
)
