                  问题描述

                  在我的 Repository 类中,我使用以下代码进行查询:

                  In my Repository class I use the following code to query:

                  $query = $this->getEntityManager()->createQuery("
                      SELECT s.term, COUNT(s.term) AS freq
                      FROM AppEntitiesSearchTerm s
                      GROUP BY s.term
                      ORDER BY s.term ASC
                  ");
                  
                  $result = $query->getResult();
                  

                  我得到的结果是这样的:

                  The result I get is something like:

                  array (size=4)
                    0 => 
                      array (size=2)
                        'term' => string '' (length=0)
                        'freq' => string '1' (length=1)
                    1 => 
                      array (size=2)
                        'term' => string 'foo' (length=3)
                        'freq' => string '1' (length=1)
                    2 => 
                      array (size=2)
                        'term' => string 'bar' (length=3)
                        'freq' => string '2' (length=1)
                    3 => 
                      array (size=2)
                        'term' => string 'baz' (length=3)
                        'freq' => string '2' (length=1)
                  

                  但我宁愿有一个关联数组作为结果:

                  But I would rather have an associative array as a result:

                  array (size=4)
                    '' => string '1' (length=1)
                    'foo' => string '1' (length=1)
                    'bar' => string '2' (length=1)
                    'baz' => string '2' (length=1)
                  

                  这是否可能没有额外的 for 循环来构建所需的数组?

                  Is this possible without an extra for-loop to build the desired array?

                  推荐答案

                  我知道它很老,但今天我不得不做几乎相同的事情,我的解决方案没有自定义水合器

                  I know its old but today I had to do almost the same, my solution without a custom hydrator

                  • 按 s.term 索引
                  • 修改 getResult() 以确保

                  喜欢

                  $result = $query->getQuery()->getResult(DoctrineORMAbstractQuery::HYDRATE_ARRAY);
                  

                  • 格式化结果
                  • 作为

                    $resultNeeded = array_map(function($value) { return $value['freq']; }, $result);
