Pagination 分页不'；在Zend框架2中不能使用HAVING子句

我实现了一个分页，类似于它的显示方式：

搜索\模型\课程表

class CourseTable {

    const RELEVANCE_TITLE = 5;
    const RELEVANCE_DESCRIPTION = 2;
    const RELEVANCE_MIN = 3;

    protected $tableGateway;

    public function __construct(TableGateway $tableGateway) {
        $this->tableGateway = $tableGateway;
    }

    public function findAllByCriteria(CourseSearchInput $input) {
        $concatDelimiter = self::CONCAT_DELIMITER;
        $select = new Select();
        $where = $this->buildWhereFromCriteria($input);
        $having = new Having();
        $select->columns(array(
            ...
        ));
        $select->from($this->tableGateway->getTable());
        $select
            ->join('...)) // and some more JOINs
        ;
        $where
            // condition
        ;
        $having
            ->greaterThanOrEqualTo('relevance', self::RELEVANCE_MIN);
        ;
        $select->where($where, Predicate::OP_AND);
        $select->having($having);
        $select->group(array('courses.id'));

        $adapter = new \Zend\Paginator\Adapter\DbSelect($select, $this->tableGateway->getAdapter());
        $paginator = new \Zend\Paginator\Paginator($adapter);
        return $paginator;

//      $resultSet = $this->tableGateway->selectWith($select);
//      return $resultSet;
    }

    public function buildRelevanceExpressionFromCriteria(CourseSearchInput $input) {
        $criteria = $input->getArrayCopy();
        $relevanceTitle = self::RELEVANCE_TITLE;
        $relevanceDescription = self::RELEVANCE_DESCRIPTION;
        $expressionSQL = <<<SQL
MATCH (coursedata.title) AGAINST ('{$criteria['keyword']}') * $relevanceTitle +
MATCH (coursedata.description) AGAINST ('{$criteria['keyword']}') * $relevanceDescription
SQL;
        return new Expression($expressionSQL);
    }

    function buildWhereFromCriteria(CourseSearchInput $input) {
        ...
    }

}

现在抛出一个异常：

这是一个框架错误吗

编辑

使用

$test=$select->getSqlString（$this->tableGateway->getAdapter（）->getPlatform（））生成的查询在
$adapter=new\Zend\Paginator\adapter\DbSelect（$select，$this->tableGateway->getAdapter（）之前的行中：

我删除了我的答案，因为我不确定你的问题到底是什么。我怀疑它与查询本身有关，它不是一个真正的bug。您能显示您正在选择的列吗（您没有选择）？另外，您尝试使用普通SQL编写的查询也会有所帮助。它不分页工作；2.当我提取查询并在MySQL客户机上执行它时，它也可以工作。该查询太长，无法发表评论，我更新了该问题。我仍然认为是这样，因为它看起来像是您按courses.id分组（对我来说已经很奇怪了，但还行），而在您的示例中，您使用的是“相关性”，它不是分组列。根据MySQL模式（即，如果仅未设置_FULL _GROUP _BY），MySQL可能会在您的会话中允许此操作，但这不会减少错误。当您设置ONLY_FULL_GROUP_BY mode时，您可以做的是测试查询是否仍然在您的客户机中工作：set sql_mode='ONLY_FULL_GROUP_BY'；是的，我现在明白了。当我禁用时，查询实际上返回了一个错误（但不是异常中的错误）：
错误代码：1055'unisportr_zf.courses.title'不在groupby
中。我将尝试重写代码，以便将
GROUP BY
using简化为标准SQL。是的，这非常简单：您只需确保HAVING子句中使用的所有列也在GROUP BY子句中列出。这非常有意义，因为您的have包含关于每个组的条件，而不是关于每一行的条件。
