如果表是通过[超级表](../super-table/)创建,更改表结构的操作只能对超级表进行。同时针对超级表的结构更改对所有通过该结构创建的表生效。对于不是通过超级表创建的表,可以直接修改表结构
## 超级表STable管理
注意:在 2.0.15 以前的版本中,并不支持 STABLE 保留字,而是写作 TABLE。也即,在本节后文的指令说明中,CREATE、DROP、ALTER 三个指令在老版本中保留字需写作 TABLE 而不是 STABLE。
- **创建超级表**
```mysql
CREATE TABLE [IF NOT EXISTS] stb_name (timestamp_field_name TIMESTAMP, field1_name data_type1 [, field2_name data_type2 ...]) TAGS (tag1_name tag_type1, tag2_name tag_type2 [, tag3_name tag_type3]);
CREATE STABLE [IF NOT EXISTS] stb_name (timestamp_field_name TIMESTAMP, field1_name data_type1 [, field2_name data_type2 ...]) TAGS (tag1_name tag_type1, tag2_name tag_type2 [, tag3_name tag_type3]);
```
创建STable, 与创建表的SQL语法相似,但需指定TAGS字段的名称和类型
创建 STable,与创建表的 SQL 语法相似,但需指定 TAGS 字段的名称和类型
说明:
1) TAGS 列的数据类型不能是timestamp类型;

2) TAGS 列名不能与其他列名相同;

## 超级表 STable 中 TAG 管理
- **添加标签**
```mysql
ALTER TABLE stb_name ADD TAG new_tag_name tag_type;
ALTER STABLE stb_name ADD TAG new_tag_name tag_type;
```
STable增加一个新的标签,并指定新标签的类型。标签总数不能超过128个,总长度不超过16k个字符。

- **删除标签**
```mysql
ALTER TABLE stb_name DROP TAG tag_name;
ALTER STABLE stb_name DROP TAG tag_name;
```
删除超级表的一个标签,从超级表删除某个标签后,该超级表下的所有子表也会自动删除该标签。
- **修改标签名**
```mysql
ALTER TABLE stb_name CHANGE TAG old_tag_name new_tag_name;
ALTER STABLE stb_name CHANGE TAG old_tag_name new_tag_name;
```
修改超级表的标签名,从超级表修改某个标签名后,该超级表下的所有子表也会自动更新该标签名。
- **修改子表标签值**
```mysql
ALTER TABLE tb_name SET TAG tag_name=new_tag_value;
ALTER STABLE tb_name SET TAG tag_name=new_tag_value;
```
说明:除了更新标签的值的操作是针对子表进行,其他所有的标签操作(添加标签、删除标签等)均只能作用于STable,不能对单个子表操作。对STable添加标签以后,依托于该STable建立的所有表将自动增加了一个标签,所有新增标签的默认值都是NULL。

注意:普通表的通配符 * 中并不包含 _标签列_。
##### 获取标签列的去重取值
从 2.0.15 版本开始,支持在超级表查询标签列时,指定 distinct 关键字,这样将返回指定标签列的所有不重复取值。
```mysql
SELECT DISTINCT tag_name FROM stb_name;
```
注意:目前 distinct 关键字只支持对超级表的标签列进行去重,而不能用于普通列。
#### 结果集列名
