类似于HQL中的%运算符

Question

我试图运行下面的代码，但我得到了一个错误。

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like %操作符。请帮帮我。我也试过在线以下，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" + "%";

Answer 1

您应该将:csid参数名称放在查询中，并在您设置的参数中添加%通配符。而且，您似乎没有在params映射中设置csid。

查询

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

Params

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