 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);

     自动建表语法也支持在一条语句中向多个表插入记录。例如：  
     ```mysql
     INSERT INTO d21001 USING meters TAGS ('Beijing.Chaoyang', 2) VALUES ('2021-07-13 14:06:34.630', 10.2, 219, 0.32) ('2021-07-13 14:06:35.779', 10.15, 217, 0.33)

     ```
     **说明：**在 2.0.20.5 版本之前，在使用自动建表语法并指定列时，子表的列名必须紧跟在子表名称后面，而不能如例子里那样放在 TAGS 和 VALUES 之间。从 2.0.20.5 版本开始，两种写法都可以，但不能在一条 SQL 语句中混用，否则会报语法错误。

 An IoT system often has many types of devices, such as smart meters, transformers, buses, switches, etc. for power grids. In order to facilitate aggregation among multiple tables, using TDengine, it is necessary to create a STable for each type of data collection point. Taking the smart meter in Table 1 as an example, you can use the following SQL command to create a STable:
 
 ```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);
 ```
 
 **Note:** The STABLE keyword in this instruction needs to be written as TABLE in versions before 2.0.15.
