TYPO3 MySQL選擇查詢，可在phpMyAdmin中使用，但不適用於TYPO3

Question

如果我在數據庫的phpMyAdmin中運行下面的代碼，則得到17條記錄，但是當我在TYPO3 6.1.4中運行它時，我得到了DB（200）中的所有記錄，為什么在TYPO3中它不能100％工作在phpMyAdmin中工作。

public function getKategorierne($catId){
        //print $catId;
        $query = $this->createQuery();
        $query->statement('SELECT * '.
                            'FROM sys_category_record_mm '.
                            'INNER JOIN sys_category ON ( uid = uid_local ) '.
                            'WHERE tablenames = "tx_origkentaurproducts_domain_model_design" '.
                            'AND sys_category_record_mm.uid_local '.
                            'IN ('.$catId.') '.
                            'ORDER BY uid_foreign');

        return $query->execute();

    }

Answer 1

以及為什么所有的引號都是逗號！？！？

$query = "
SELECT * 
  FROM sys_category_record_mm r
  JOIN sys_category c
    ON uid = uid_local 
 WHERE tablenames = 'tx_origkentaurproducts_domain_model_design' 
   AND r.uid_local IN ('$catId') 
 ORDER 
    BY uid_foreign;
";
