nested exception is java.sql.SQLException: ORA-00932: 数据类型不一致: 应为 -, 但却获得 CLOB

问题：nested exception is java.sql.SQLException: ORA-00932: 数据类型不一致: 应为 -, 但却获得 CLOB

原因是条件查询时，我的库中的类型是clob类型就报错了，

解决方法：

改成 to_char(a.progressAndPlan)，

如：

if (StringHelper.isNotEmpty(bMentorid)){
//    selectSql=selectSql + "and field005 ='"+bMentorid+"' ";
      String[] objnames = new String[0];
      objnames = bMentorid.split(",");
      String bMentorids="";
      for (int i=0;i          if (i==objnames.length-1){
            bMentorids=bMentorids+"'"+objnames[i]+"'";
         }else {
            bMentorids=bMentorids+"'"+objnames[i]+"'"+",";
         }
      }
      selectSql=selectSql + " and to_char(field005) in ("+bMentorids+") ";

       bMentoridname=dateservice.getValue("select objname from humres where id in ("+bMentorids+")");//企业导师名称
   }
