Eigenschaftswert
A Boolean property value that specifies whether the computed value of the Column object is saved with the data. If True, the computed value of the Column object is saved with the data. If False (default), the computed value of the Column object is computed every time the column data is requested. The IsPersisted property can only be set to True for computed columns. Otherwise, it will cause an error.
