Hibernate DB2 ROW_NUMBER（）error

Question

當我使用DB2的ROW_NUMBER（）時，我在Hibernate中遇到了問題，它說查詢異常：未定義的別名：ROW_NUMBER。該怎麼辦？謝謝

String strQuery= " SELECT c_.name, c_.id, c_.description, ROW_NUMBER() OVER(ORDER BY  
        c_.name) AS rownum FROM Category as c_ "; 
Query query = getHibernateTemplate().getSessionFactory(). 
getCurrentSession().createQuery(strQuery); 

Answer 1

ROW_NUMBER()在DB2中不是有效的函數，但它在SQL Server中。你想要rownumber()函數。更改您的查詢以下，它應該工作：

String strQuery= " SELECT c_.name, c_.id, c_.description, rownumber() OVER(ORDER BY  
       c_.name) AS rownum FROM Category as c_ ";
