Both interval_val and sliding_value are time durations which have 3 forms of representation.
|

- INTERVAL(1s, 500a) SLIDING(1s), the unit char should be any one of a (millisecond), b (nanosecond), d (day), h (hour), m (minute), n (month), s (second), u (microsecond), w (week), y (year).

在上述语法中的具体限制如下
|
||||
其中，interval_val 和 sliding_val 都表示时间段, 语法上支持三种方式，举例说明如下:
|
||||
- INTERVAL(1s, 500a) SLIDING(1s), 自带时间单位的形式，其中的时间单位是单字符表示, 分别为: a (毫秒), b (纳秒), d (天), h (小时), m (分钟), n (月), s (秒), u (微妙), w (周), y (年).
|
||||
- INTERVAL(1000, 500) SLIDING(1000), 不带时间单位的形式，将使用查询库的时间精度作为默认时间单位，当存在多个库时默认采用精度更高的库.
|
||||
- INTERVAL('1s', '500a') SLIDING('1s'), 自带时间单位的字符串形式，字符串内部不能有任何空格等其它字符.
