- 输出结果缺省按首列时间戳升序排序，但可以指定按降序排序( _c0 指首列时间戳)。使用 ORDER BY 对其他字段进行排序为非法操作。
- 参数 LIMIT 控制输出条数，OFFSET 指定从第几条开始输出。LIMIT/OFFSET 对结果集的执行顺序在 ORDER BY 之后。且 `LIMIT 5 OFFSET 2` 可以简写为 `LIMIT 2, 5`。
* 在有 GROUP BY 子句的情况下，LIMIT 参数控制的是每个分组中至多允许输出的条数。
- 参数 SLIMIT 控制由 GROUP BY 指令划分的分组中，至多允许输出几个分组的数据。且 `SLIMIT 5 OFFSET 2` 可以简写为 `SLIMIT 2, 5`。
- 参数 SLIMIT 控制由 GROUP BY 指令划分的分组中，至多允许输出几个分组的数据。且 `SLIMIT 5 SOFFSET 2` 可以简写为 `SLIMIT 2, 5`。
- 通过 “>>” 输出结果可以导出到指定文件。
### 支持的条件过滤操作

- 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：TOP、BOTTOM、DIFF 以及四则运算）。
- 查询过滤、聚合等操作按照每个切分窗口为独立的单位执行。聚合查询目前支持三种窗口的划分方式：
1. 时间窗口：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。当 SLIDING 与 INTERVAL 取值相等的时候，滑动窗口即为翻转窗口。
2. 状态窗口：使用整数（布尔值）或字符串来标识产生记录时设备的状态量，产生的记录如果具有相同的状态量取值则归属于同一个状态窗口，数值改变后该窗口关闭。状态量所对应的列作为 STAT_WINDOW 语句的参数来指定。
2. 状态窗口：使用整数（布尔值）或字符串来标识产生记录时设备的状态量，产生的记录如果具有相同的状态量取值则归属于同一个状态窗口，数值改变后该窗口关闭。状态量所对应的列作为 STATE_WINDOW 语句的参数来指定。
3. 会话窗口：时间戳所在的列由 SESSION 语句的 ts_col 参数指定，会话窗口根据相邻两条记录的时间戳差值来确定是否属于同一个会话——如果时间戳差异在 tol_val 以内，则认为记录仍属于同一个窗口；如果时间变化超过 tol_val，则自动开启下一个窗口。
- WHERE 语句可以指定查询的起止时间和其他过滤条件。
- 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：
