Zend Framerwork DB DDL更新 [英] Zend framerwork DB DDL update

问题描述

我是zend的新手，我想为应用程序使用DB模块。

I am new to zend and i want to use the DB module for an application.

我有此代码

$DB = new Zend\Db\Adapter\Adapter(array(
    'driver' => 'Mysqli',
    'database' => 'database',
    'username' => 'user',
    'password' => 'pass'
));
use Zend\Db\Sql\Ddl;
use Zend\Db\Sql\Ddl\Column;
use Zend\Db\Sql\Ddl\Constraint;
$table = new Ddl\CreateTable('table');
$table->setTable('table');
$table->addColumn(new Column\Integer('id',false,NULL,array('autoincrement'=>true)));
$table->addColumn(new Column\Varchar('name', 255));
$table->addConstraint(new Constraint\PrimaryKey('id'));

表未创建，是否有更新功能？我找不到它。

Table is not created, there is an update function? i can't find it.

推荐答案

您创建了 DDL语句对象和 Adapter ，但您尚未执行它。您还需要1个对象才能执行，该对象是 SQL 实例。在您的情况下，它看起来可能像这样：

You created DDL statement object and Adapter, but you haven't executed it. You will need 1 more object for execution and that's SQL instance. In your case it could look like this:

use Zend\Db\Sql\Sql;

// your code

$sql = new Sql($DB);

$DB->query(
    $sql->getSqlStringForSqlObject($table),
    $DB::QUERY_MODE_EXECUTE
);
