Question

我只是创建一个SQL语句，并希望将它放在我的Typo3扩展中的有效查询构建器请求中。

SQL是

SELECT FROM_UNIXTIME(tx_operations_domain_model_operation.begin, '%Y') as year,
    count(tx_operations_operation_type_mm.`uid_foreign`) as cont,
    tx_operations_domain_model_type.`title`
    FROM tx_operations_domain_model_operation

    INNER JOIN
    tx_operations_operation_type_mm ON (`tx_operations_operation_type_mm`.`uid_local` = tx_operations_domain_model_operation.uid)
    INNER JOIN
    tx_operations_domain_model_type ON (`tx_operations_domain_model_type`.`uid` = `tx_operations_operation_type_mm`.`uid_foreign`)

    GROUP BY FROM_UNIXTIME(tx_operations_domain_model_operation.begin, '%Y'), tx_operations_operation_type_mm.`uid_foreign`;

这是我在控制器中尝试的内容

$queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable('tx_operations_domain_model_operation');
    $statement = $queryBuilder
        ->select('tx_operations_domain_model_operation.begin, \'%Y\') as year', 'count(tx_operations_operation_type_mm.`uid_foreign`) as cont')
        ->from('tx_operations_domain_model_operation')
        ->join(
            'tx_operations_domain_model_operation',
            'tx_operations_operation_type_mm',
            $queryBuilder->expr()->eq('tx_operations_operation_type_mm.uid_local', $queryBuilder->quoteIdentifier('tx_operations_domain_model_operation.uid'))
        )
        ->join(
            'tx_operations_operation_type_mm',
            'tx_operations_domain_model_type',
            $queryBuilder->expr()->eq('tx_operations_domain_model_type.uid_local', $queryBuilder->quoteIdentifier('tx_operations_operation_type_mm.uid_foreign'))
        )
        ->groupBy('UNIXTIME(tx_operations_domain_model_operation.begin, \'%Y\')', 'tx_operations_operation_type_mm.`uid_foreign')
        ->execute();

任何想法查询构建器表示必须如何？

我在实习期间一直在使用QueryBuilder，我认为你错过了一个别名：

   ->join(
      'tt_content_orig',
      'sys_language',
      'sys_language', /** Insert alias name, in this case it's the same name **/
      $queryBuilder->expr()->eq(
         'tt_content_orig.sys_language_uid',
         $queryBuilder->quoteIdentifier('sys_language.uid')
      )

我一直在使用存储库文件。
