需求是如果登录者为21981和14433,那么proplist多选下拉框就算没选中点击查询也是默认查询电商客户,如果不是者两个账号,那么proplist多选下拉框就算没选中点击查询也是查询所有,现在这样有问题该如何解决 如下Sql"+if(len(propList)=0 &&$fr_username ="21981" && $fr_username ="14433",""," and cusattribute in ('"+replace(propList,",","','")+"')")+""+if(len(propList)=0 &&($fr_username ="21981" || $fr_username ="14433")," and cusattribute='电商客户'"," and cusattribute in ('"+replace(propList,",","','")+"')")+"
