+### description
+函数array_range的别称
+
+#### Syntax
+
+```sql
+ARRAY<Int> sequence(Int end)
+ARRAY<Int> sequence(Int start, Int end)
+ARRAY<Int> sequence(Int start, Int end, Int step)
+ARRAY<Datetime> sequence(Datetime start_datetime, Datetime end_datetime)
+ARRAY<Datetime> sequence(Datetime start_datetime, Datetime end_datetime,
INTERVAL Int interval_step UNIT)
+```
+1. 生成int数组：
+参数均为正整数 start 默认为 0, step 默认为 1。
+最终返回一个数组，从start 到 end - 1, 步长为 step。
+2. 生成日期时间数组：
+至少取两个参数。
+前两个参数都是datetimev2，第三个是正整数。
+如果缺少第三部分，则`INTERVAL 1 DAY`将为默认值。
+UNIT 支持年/月/周/日/小时/分钟/秒。
+返回 start_datetime 和最接近 end_datetime 之间的 datetimev2 数组（按 Interval_step UNIT 计算）。
+
+### notice
+
+`仅支持向量化引擎中使用`
