其中 `tag_list` 是标签列的列表，还可以包括tbname伪列。

其中 `tag_list` 是标签列的列表，还可以包括 tbname 伪列。
TDengine 按如下方式处理标签切分子句：
标签切分子句位于 `WHERE` 子句之后，且不能和 `JOIN` 子句一起使用。
标签切分子句将超级表数据按指定的标签组合进行切分，然后对每个切分的分片进行指定的计算。计算由之后的子句定义（窗口子句、`GROUP BY` 子句或`SELECT` 子句）。
标签切分子句可以和窗口切分子句（或 `GROUP BY` 子句）一起使用，此时后面的子句作用在每个切分的分片上。例如，下面的示例将数据按标签 `location` 进行分组，并对每个组按10分钟进行降采样，取其最大值。

在上述语法中的具体限制如下
### 窗口切分查询中使用函数的限制
- 在聚合查询中，function_list 位置允许使用聚合和选择函数，并要求每个函数仅输出单个结果（例如：COUNT、AVG、SUM、STDDEV、LEASTSQUARES、PERCENTILE、MIN、MAX、FIRST、LAST），而不能使用具有多行输出结果的函数（例如：DIFF 以及四则运算）。
- 此外 LAST_ROW 查询也不能与窗口聚合同时出现。
- 标量函数（如：CEIL/FLOOR 等）也不能使用在窗口聚合查询中。
### 窗口子句的规则
- 窗口子句位于标签切分子句之后，GROUP BY子句之前，且不可以和GROUP BY子句一起使用。
- 窗口子句将数据按窗口进行切分，对每个窗口进行SELECT列表中的表达式的计算，SELECT列表中的表达式只能包含：
- 窗口子句位于标签切分子句之后，GROUP BY 子句之前，且不可以和 GROUP BY 子句一起使用。
- 窗口子句将数据按窗口进行切分，对每个窗口进行 SELECT 列表中的表达式的计算，SELECT 列表中的表达式只能包含：
- 常量。
- 聚集函数。
- 包含上面表达式的表达式。
- 窗口子句不可以和GROUP BY子句一起使用。
- 窗口子句不可以和 GROUP BY 子句一起使用。
- WHERE 语句可以指定查询的起止时间和其他过滤条件。
### FILL 子句
FILL 语句指定某一窗口区间数据缺失的情况下的填充模式。填充模式包括以下几种：
1. 不进行填充：NONE（默认填充模式）。
2. VALUE 填充：固定值填充，此时需要指定填充的数值。例如：FILL(VALUE, 1.23)。这里需要注意，最终填充的值受由相应列的类型决定，如FILL(VALUE, 1.23)，相应列为INT类型，则填充值为1。
3. PREV 填充：使用前一个非 NULL 值填充数据。例如：FILL(PREV)。
4. NULL 填充：使用 NULL 填充数据。例如：FILL(NULL)。
5. LINEAR 填充：根据前后距离最近的非 NULL 值做线性插值填充。例如：FILL(LINEAR)。
6. NEXT 填充：使用下一个非 NULL 值填充数据。例如：FILL(NEXT)。

```
使用时间窗口需要注意：
- 聚合时间段的窗口宽度由关键词 INTERVAL 指定，最短时间间隔 10 毫秒（10a）；并且支持偏移 offset（偏移必须小于间隔），也即时间窗口划分与“UTC 时刻 0”相比的偏移量。SLIDING 语句用于指定聚合时间段的前向增量，也即每次窗口向前滑动的时长。
- 使用 INTERVAL 语句时，除非极特殊的情况，都要求把客户端和服务端的 taos.cfg 配置文件中的 timezone 参数配置为相同的取值，以避免时间处理函数频繁进行跨时区转换而导致的严重性能影响。
- 返回的结果中时间序列严格单调递增。
