FluentPDO备忘

创建PDO实例

$dsn = 'mysql:host=localhost;dbname=test;charset=utf8';
            $username = 'username';
            $password = 'password';
$pdo = new PDO($dsn, $username, $password);

创建FPDO实例

$fPdo = new FluentPDO($pdo);

数据库操作

查询

$query = $fpdo->from('article')->where('id', 1);
// or shortly if you select one row by primary key
$query = $fpdo->from('user', 1);

插入

$values = array('title' => 'article 1', 'content' => 'content 1');
$query = $fpdo->insertInto('article')->values($values)->execute();
// or shortly
$query = $fpdo->insertInto('article', $values)->execute();

更新

$set = array('published_at' => new FluentLiteral('NOW()'));
$query = $fpdo->update('article')->set($set)->where('id', 1)->execute();
// or shortly if you update one row by primary key
$query = $fpdo->update('article', $set, 1)->execute();

删除

$query = $fpdo->deleteFrom('article')->where('id', 1)->execute();
// or shortly if you delete one row by primary key
$query = $fpdo->deleteFrom('article', 1)->execute();

注意：INSERT, UPDATE and DELETE将会在->execute()之后执行

高级一点的

leftjoin

$query = $fpdo->from('article')
              ->leftJoin('user ON user.id = article.user_id')
              ->select('user.name');

如果有主键、外键等，可以简化成

$query = $fpdo->from('article')->leftJoin('user')->select('user.name');

或者

$query = $fpdo->from('article')->select('user.name');

以上三条命令均等价于

SELECT article.*, user.name 
FROM article 
LEFT JOIN user ON user.id = article.user_id
