调用存储过程（MySQL）会从Hibernate中抛出异常

标签： java mysql hibernate stored-procedures

我通过hibernate调用了mySQL存储过程，但它总是给我错误。

以下是代码 - 

SQLQuery query = session.createSQLQuery("call test()").addEntity(Organisation.class);
List result = query.list();

以下是错误堆栈跟踪 -

以下是存储过程的代码，它完美地运行 - 

DELIMITER ;;
CREATE PROCEDURE `test`()
BEGIN

SELECT * FROM `Dim_Organisation`;
PREPARE stmt FROM @query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

END;;
DELIMITER ;

答案 0 :(得分：0)

我通过从存储过程中删除以下语句来解决这个问题

 PREPARE stmt FROM @query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
