IsDeterministic 屬性

取得或設定 Boolean 屬性值，這個值會指定計算資料行的值是否可以在後續引動過程中變更。

命名空間：  Microsoft.SqlServer.Management.Smo

屬性值

型別：System. . :: . .Boolean
Boolean 值，指定計算資料行是否可以在引動過程之間變更。

備註

If the computed column contained a value that was calculated from the current date, for example, the column would not be deterministic. The value of the column would change as the date changes and therefore would be different for subsequent invocations.
