AllowIdentity Property

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能,並規劃修改目前使用這項功能的應用程式。

備註

The SQL Server identity property is defined for data types that can accept numeric values. A column defined with the identity property is defined with a starting value and a step value. SQL Server generates values for the column by querying the last applicable value and adding the step value.
