    用的是哪个版本的物联网,另外看下控制台的详细报错日志,日志提交的时候,麻烦用编辑器的这个包裹一下,这样能看的清晰一些

  • 使用的是iot 和bladex 合并以后的,具体那个版本在哪看(项目bladex-server 运行端口是8800)


    报错消息里有172.17.0.1:8800

    看报错,是超级表类型冲突了。

    这个错误的主要内容提示说,在尝试使用 ALTER STABLE 语句修改超级表 device_property_b12fldwxuwhs 中的 humidity 列的数据类型时遇到问题。错误详细说明了只有 varbinary、binary、nchar、geometry 这类类型的列长度可以被修改,并且只能增加长度,不能减少。


    使用tdengine的时候,每次发布物模型,都会发布一次超级表,对超级表进行变更。但是如果字段变化属性变化的时候,tdengine本身不支持,也就无法修改成功了。正常情况下物模型定下后一般也不会再改类型,所以设计的时候要注意下。


    解决方案就是手动删掉老的超级表(如果有重要数据,则先备份或者导出),删掉后再点击发布就能创建超级表成功了。
