参数

name
String

序列名称。

schema
String

包含序列的架构,或使用 null 默认架构。

startValue
Int64

序列将启动的值,默认为 1。

incrementBy
Int32

在序列中生成下一个值时递增的量,默认为 1。

minValue
Nullable<Int64>

序列的最小值,如果未指定,则 null 为 。

maxValue
Nullable<Int64>

序列的最大值,如果未指定,则 null 为 。

cyclic
Boolean

指示在达到最大值时序列是否会重新启动。

返回

一个生成器,允许将批注添加到操作中。
