Lax*_*man 8 where-clause zend-framework2
我试图从另一个表中尚未出现的表中获取结果.为此,我在where子句中使用subQuery和NOT IN表达式.正常的sql工作如下:
SELECT `products`.* FROM `products` WHERE `products`.`pro_id` **NOT IN** (
SELECT `product_collection`.`pro_id` AS `pro_id` FROM `product_collection` WHERE `coll_id` = '6' ) AND products.pro_id IN (55,56,57,62)

我正在为项目使用zf2.问题是我不知道如何在where子句中使用NOT IN表达式.我们可以在Where子句中使用where-> in()作为IN表达式.例如.
//$productIds is an array
//$collectionId is an id
$subSelect = $this->getRawSql()->select('product_collection');
$subSelect -> columns(array('pro_id'));
$subSelect -> where(array('coll_id'=>$collectionId));
$select = $this->getRawSql()->select('products');
$select -> **where->in**('products.pro_id', $subSelect)
-> where->in('products.pro_id',$productIds);

但我不知道如何使用NOT IN表达式.

像使用In()一样使用notIn().
请参阅:http://framework.zend.com/apidoc/2.1/classes/Zend.Db.Sql.Predicate.NotIn.html
$subSelect = $this->getRawSql()->select('product_collection');
$subSelect -> columns(array('pro_id'));
$subSelect -> where(array('coll_id'=>$collectionId));
$select = $this->getRawSql()->select('products');
$select ->where->notIn('products.pro_id', $subSelect)
->where->in('products.pro_id',$productIds);

编辑:
或者改用它
$select ->where
->addPredicate(new Zend\Db\Sql\Predicate\Expression('products.pro_id NOT IN (?)',
array($subSelect)))
