substring在HQL和java中用法区分

条件：reportNum = 评报字(2010)1010

当HQL 语句中：substring(reportNum,10,4)  得到结果为 1010

例句：String hql = "from Report r where substring(r.reportNum,10,4)="+setReportNum;

当java语句中：reportNum.substring(9, 13)  得到结果为 1010

例句：Integer number1 = Integer.valueOf(report1.getReportNum().substring(9, 13));
