mysql - ThinkPHP3.2.3中连贯操作问题？

问题描述

问 题

代码

SQL语句为
SELECT crsIpint,crsIpout,crsName,wfdz,CheckStatus,0 AS flag FROM vehicle.crossing AS t1 LEFT JOIN ( SELECT * FROM caminfo.devs_ip_status WHERE type = 95 ) AS t2 ON( t1.crsId = t2.DeviceID ) WHERE t1.type <> 0 LIMIT 0,20 UNION ( SELECT ip AS crsIpint,"" AS crsIpout,name AS crsName,"主服务器" AS wfdz,1 AS CheckStatus,1 AS flag FROM trk.devs_other WHERE type = 101 )

我想要的是
SELECT crsIpint,crsIpout,crsName,wfdz,CheckStatus,0 AS flag FROM vehicle.crossing AS t1 LEFT JOIN ( SELECT * FROM caminfo.devs_ip_status WHERE type = 95 ) AS t2 ON( t1.crsId = t2.DeviceID ) WHERE t1.type <> 0 UNION ( SELECT ip AS crsIpint,"" AS crsIpout,name AS crsName,"主服务器" AS wfdz,1 AS CheckStatus,1 AS flag FROM trk.devs_other WHERE type = 101 ) LIMIT 0,20
这个数据 请问各位大神代码连贯操作该怎么写？？？

而且用原生SQL 总是报query方法不存在

解决方案

$Model = M(); 实例化时加个斜杠就好了 query就可以用了
