Question

我正在尝试运行下面的代码但是我收到了错误。

public MdFeedHandOff getFeedByHandOff(Integer handoff, Integer csiID){
        logger.error("*************getFeedByHandOff(): handoff value is "+handoff);
        String hql = "FROM MdFeedHandOff a WHERE a.handoff = :handoff  and  a.active  in ('A','I') and to_char(a.handoff) like :csiID%";
        Map<String, Object> param = new HashMap<String, Object>();
        param.put("handoff", handoff);
        List<MdFeedHandOff> batchJobList = searchForList(hql, param);
        return batchJobList.isEmpty()?null:batchJobList.get(0);
    }

我想在hql中使用％运算符。请帮助我。我也尝试过以下行，但它不起作用。

String hql = "FROM MdFeedHandOff a WHERE a.handoff = :handoff  and  a.active  in ('A','I') and to_char(a.handoff) like :csiID" + "%";

您应该在查询中添加:csid参数名称，并在您设置的参数中添加％通配符。你似乎也没有在参数图中设置csid。

<强>查询：

FROM MdFeedHandOff a WHERE a.handoff = :handoff 
     and  a.active  in ('A','I') and to_char(a.handoff) like :csiID";

<强> PARAMS ：

Map<String, Object> param = new HashMap<String, Object>();
param.put("handoff", handoff);
param.put("csiID", csiId.toString()+"%");

与HQL中的％运算符一样
