Jfinal 处理oracle CLOB? 400 报错
Jfinal 处理oracle CLOB? 400 报错
public CommandMission findLastCommandMissionByDevId(String devId) { return findFirst("SELECT * FROM D_COMMANDMISSION WHERE DEVID = ? AND COMMANDSTATUS = 1 AND nvl(MESSAGE,'')!='' ORDER BY LASTTIME",devId); }
我有这样一个方法，其中message为clob，如果这个devid查出数据能正常返回，如果没有数据就会报以下异常
