ordinal parameter mismatch
© 版权声明:本文为博主原创文章,转载请注明出处
错误描述:Caused by: org.hibernate.HibernateException: ordinal parameter mismatch
错误代码:
/** * 查看该黑名单类型是否已存在 * * @param phone_number * 用户号码 * @return */ public int checkBlack(String phone_number, String call_type, String location_id) { Object[] obj = null;// 参数 String condition = null;// 条件 condition = "phone_number = ? and call_type = ? and location_id = ?"; obj = new Object[] { phone_number, Short.valueOf(call_type), location_id }; List<TphBlack> list = tphBlackDao.find(condition, obj, new OrderBy()); if (list == null || list.size() == 0) { return 0;// 不存在 } else { return 1;// 已存在 } }
错误截图:
解决方案:将查询条件中带有"call"的字段放在第一位,使其在语句中的位置在"?"和"="之前。
正确代码:
/** * 查看该黑名单类型是否已存在 * * @param phone_number * 用户号码 * @return */ public int checkBlack(String phone_number, String call_type, String location_id) { Object[] obj = null;// 参数 String condition = null;// 条件 // 带有call的字段必须放在第一个=或?之前,否则报错ordinal parameter mismatch condition = "call_type = ? and phone_number = ? and location_id = ?"; obj = new Object[] { Short.valueOf(call_type), phone_number, location_id }; List<TphBlack> list = tphBlackDao.find(condition, obj, new OrderBy()); if (list == null || list.size() == 0) { return 0;// 不存在 } else { return 1;// 已存在 } }
原因分析:查看hibernate-core.jar中的org.hibernate.engine.query包下的ParameterParser.class的源码发现,在parse方法中,将sql语句中的call当做了存储过程中的call关键字。
