參數

name

String

序列名稱。

schema

String

包含序列的結構，或 null 使用預設架構。

incrementBy

Int32

產生序列下一個值時，該數值會增加，預設為 1。

minValue

Nullable<Int64>

序列的最小值，或 null 若未指定。

maxValue

Nullable<Int64>

序列的最大值，或 null 若未指定。

cyclic

Boolean

表示當達到最大值時，序列是否會重新開始。

oldIncrementBy

Int32

前一個值在產生下一個值時會增加，預設為 1。

oldMinValue

Nullable<Int64>

序列的先前最小值，或 null 若未指定。

oldMaxValue

Nullable<Int64>

序列的先前最大值，或 null 若未指定。

oldCyclic

Boolean

表示當達到最大值時，序列是否會重新開始。
