RowGuidCol 属性

获取或设置 Boolean 属性值，该值指定该列是否自动用唯一的 GUID 值更新。

命名空间：  Microsoft.SqlServer.Management.Smo
程序集：  Microsoft.SqlServer.Smo（在 Microsoft.SqlServer.Smo.dll 中）

语法

声明
<SfcPropertyAttribute(SfcPropertyFlags.None Or SfcPropertyFlags.Standalone Or SfcPropertyFlags.SqlAzureDatabase Or SfcPropertyFlags.Design)> _
Public Property RowGuidCol As Boolean
    Get
    Set
用法
Dim instance As Column
Dim value As Boolean

value = instance.RowGuidCol

instance.RowGuidCol = value

[SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase|SfcPropertyFlags.Design)]
public bool RowGuidCol { get; set; }

[SfcPropertyAttribute(SfcPropertyFlags::None|SfcPropertyFlags::Standalone|SfcPropertyFlags::SqlAzureDatabase|SfcPropertyFlags::Design)]
public:
property bool RowGuidCol {
    bool get ();
    void set (bool value);
}

[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase|SfcPropertyFlags.Design)>]
member RowGuidCol : bool with get, set

function get RowGuidCol () : boolean
function set RowGuidCol (value : boolean)

属性值

类型：System. . :: . .Boolean
一个 Boolean 值，指定列是否包含一个自动更新的唯一 GUID 值。
如果为 True，则列自动用唯一的 GUID 值更新。否则为 False（默认值）。

注释

The RowGuidCol property is equivalent to the ADD or DROP ROWGUIDCOL Transact-SQL statement in the ALTER TABLE statement

When this property is set to True, the column is automatically updated with a unique GUID value. If the data is copied to another table, the GUID value will not be identical to the original column value. There is only one RowGuidCol column allowed per table.
