問題描述

我想弄清楚如何在 where 子句中使用 OR 進行 Mysql Select.默認情況下，where 語句中的所有子句都是 AND 運算的，經過幾個小時的嘗試和失敗，查看網絡無法使其工作.在 ZF1 中它將是 orWhere() 但在 ZF2 中沒有.

I am trying to figure out how to make a Mysql Select with an OR in where Clause. By default all clauses in where statement are ANDed and after some hours of try and fail and looking the net can't make it work. In ZF1 it would be an orWhere() but there is not in ZF2.

這是我在 AbstracttableGateway 中的代碼:

This is the code i have inside a AbstracttableGateway:

$resultSet = $this->select(function (Select $select) use ($searchstring) {
             $select->join('users','blog_posts.id_user = users.id',array('name'))
                    ->join('blog_categories','blog_posts.id_category = blog_categories.id', array(
                                           'cat_name'   => 'name',
                                           'cat_alias' => 'alias',
                                           'cat_image'  => 'icon'))
                    ->order('date DESC');
                    //->where("title LIKE '%" .$searchstring . "%' OR content LIKE '%". $searchstring ."%'")
            $select->where->like('content','%'.$searchstring.'%');
            $select->where->like('title','%'.$searchstring.'%');
        }
    );
    return $resultSet;

帶有 $select->where->like 的行是 AND 運算的，我希望它們帶有 OR.我應該改變什么?

the lines with the $select->where->like are the ones that are ANDed and I want them with OR. What should I change?

推薦答案

ZF2 中沒有 orWhere，但你可以使用 ZendDbSqlPredicate 的任意組合代碼>對象.對于 OR，在 PredicateSet 和 PredicateSet::COMBINED_BY_OR 中使用 2 個謂詞.

There is no orWhere in ZF2, but you could use any combination of ZendDbSqlPredicate objects. For OR use 2 predicates in a PredicateSet with PredicateSet::COMBINED_BY_OR.

關于它的文檔不多，但您可以瀏覽源代碼 - 現在.

There's not much documentation for it, but you could browse the source - for now.

編輯:示例

use ZendDbSqlPredicate;

$select->where(array(
    // ...
    new PredicatePredicateSet(
        array(
            new PredicateLike('content', '%'.$searchstring.'%'),
            new PredicateLike('title', '%'.$searchstring.'%'),
        ),
        PredicatePredicateSet::COMBINED_BY_OR
    ),
    // ...
));
