获取 Boolean 属性值，该值指定表是否具有更新触发器。

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 HasUpdateTrigger As Boolean
    Get
用法
Dim instance As Table
Dim value As Boolean

value = instance.HasUpdateTrigger

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

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

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

function get HasUpdateTrigger () : boolean

属性值

类型：System. . :: . .Boolean
一个 Boolean 值，该值指定是否对表定义了 update 触发器。
如果为 True，则对表定义了 update 触发器。否则为 False（默认值）。

注释

An update trigger executes when a row of data is updated.

示例

The following code example shows how to list each table in the AdventureWorks2008R2 database with an update trigger.

C#

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

foreach (Table tb in db.Tables) 
{
    if (tb.HasUpdateTrigger == true)
   {
      Console.WriteLine("The " + tb.Name + " table has an update trigger");
   }
}

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.HasUpdateTrigger -eq $TRUE)
   {
      Write-Host "The" $tb.Name "table has an update trigger."
   }
}
