一个物联网系统往往存在多种类型的设备比如对于电网存在智能电表、变压器、母线、开关等等。为便于多表之间的聚合使用TDengine, 需要对每个类型的数据采集点创建一超级表。以表一中的智能电表为例可以使用如下的SQL命令创建超级表
```mysql
CREATE STABLE meters (ts timestamp, current float, voltage int, phase float) TAGS (location binary(64), groupdId int);
CREATE STABLE meters (ts timestamp, current float, voltage int, phase float) TAGS (location binary(64), groupId int);
```
**注意:**这一指令中的 STABLE 关键字,在 2.0.15 之前的版本中需写作 TABLE 。
