关于DB+RECORD操作oracle数据库的问题?报错

@JFinal 你好，想跟你请教个问题：我操作oracle数据库，插入一条记录

Record user = new Record().set("userid", userid).set("favid", favid).set("type", type).set("guid",StringUtils.getGuid());
Db.save("TDATA_FAV","GUID", user);

这个时候报错，com.jfinal.plugin.activerecord.ActiveRecordException: java.sql.SQLException: 不支持的特性
