Description: 

SQL that executes data definition language (DDL) statements should be processed through the protected Schema::executeDdlStatement() method and no longer with the Connection::query() method. This allows Drupal’s transaction manager to handle gracefully autocommits that occur when a DDL statement is executed while a Drupal transaction stack is active, for databases that do not support transactional DDL (MySql, Oracle, ...).

Within the Schema class of a database driver,

Before

$this->connection->query('DROP TABLE {test}');

After

$this->executeDdlStatement('DROP TABLE {test}');
