在 cakephp3 中打印 ORM 查询构建器的 SQL 查询

Question

如何打印 ORM 查询

$query = $articles->find('all')->contain(['Comments']);

例如打印=>

SELECT * FROM comments WHERE article_id IN (comments);

Answer 1

使用调试函数包装您的 ORM 查询结果将显示 SQL 和绑定参数：

debug($query);

你也可以类似的用调试查看查询结果 function.See CakePHP 3: retrieving data and result sets — Debugging Queries and ResultSets

Answer 2

我更喜欢这个：

public function __debugInfo()
    {
        return [
            'query' => $this->_query,
            'items' => $this->toArray(),
        ];
    }

// Print the query
debug($query->__debugInfo()['sql']);

// Prints this
SELECT * FROM comments WHERE article_id IN (comments);

那$query->sql()呢？

$qb = $this->Person->find()->select(["id", "text" => "concat(Name,' ',Family)"])
            ->where(['id >' => 0])
            ->where($query ? ["OR" => $filters] : null)
            ->limit(10);
dd($qb->sql());

结果：

.../src/Controller/ClientController.php (line 86)
'SELECT Person.id AS `Person__id`, concat(Name,' ',Family) AS `text` FROM person Person WHERE (id > :c0 AND (Family like '%sam%' OR Name like '%sam%' OR Family like '%sam%' OR Name like '%sam%')) LIMIT 10'
