IsIndexable 属性

获取 Boolean 属性值，该值指定是否可将某一索引置于表上。

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)> _
Public ReadOnly Property IsIndexable As Boolean
    Get
用法
Dim instance As Table
Dim value As Boolean

value = instance.IsIndexable

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

[SfcPropertyAttribute(SfcPropertyFlags::None|SfcPropertyFlags::Standalone|SfcPropertyFlags::SqlAzureDatabase)]
public:
property bool IsIndexable {
    bool get ();
}

[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase)>]
member IsIndexable : bool

function get IsIndexable () : boolean

属性值

类型：System. . :: . .Boolean
一个 Boolean 值，该值指定是否可将索引置于表上。
如果为 True，则可将索引置于表上。否则为 False（默认值）。

注释

Most tables can support an index. However, some that cannot support an index because of the nature of the data.

示例

The following code example shows how to list all of the indexable tables in the AdventureWorks2008R2 database.

C#

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2008R2"];

foreach (Table tb in db.Tables) 
{
   if (tb.IsIndexable == True)
   {
      Console.WriteLine("The " + tb.Name + " table is indexable.");
   }
}

Powershell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")

Foreach ($tb in $db.Tables) 
{
   If ($tb.IsIndexable -eq $TRUE)
   {
      Write-Host "The" $tb.Name "table is indexable."
   }
}
