获取一个 Boolean 属性值，该值指定是否为数据库自动更新统计信息。

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.Deploy)> _
Public Property AutoUpdateStatisticsEnabled As Boolean
    Get
    Set
用法
Dim instance As Database
Dim value As Boolean

value = instance.AutoUpdateStatisticsEnabled

instance.AutoUpdateStatisticsEnabled = value

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

[SfcPropertyAttribute(SfcPropertyFlags::None|SfcPropertyFlags::Standalone|SfcPropertyFlags::SqlAzureDatabase|SfcPropertyFlags::Deploy)]
public:
virtual property bool AutoUpdateStatisticsEnabled {
    bool get () sealed;
    void set (bool value) sealed;
}

[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase|SfcPropertyFlags.Deploy)>]
abstract AutoUpdateStatisticsEnabled : bool with get, set
[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase|SfcPropertyFlags.Deploy)>]
override AutoUpdateStatisticsEnabled : bool with get, set

final function get AutoUpdateStatisticsEnabled () : boolean
final function set AutoUpdateStatisticsEnabled (value : boolean)

属性值

类型：System. . :: . .Boolean
一个 Boolean 值，该值指定是否为数据库自动更新统计信息。
如果为 True，则为数据库自动更新统计信息。否则为 False（默认值）。

实现

IDatabaseOptions. . :: . .AutoUpdateStatisticsEnabled

注释

The AutoUpdateStatisticsEnabled property is equivalent to setting the AUTO_UPDATE_STATISTICS ON option in the ALTER DATABASE Transact-SQL statement.

示例

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")

'Display the current options for statistics.
Console.WriteLine("Automatically create statistics = " + _
db.AutoCreateStatisticsEnabled.ToString)
Console.WriteLine("Automatically update statistics = " + _
db.AutoUpdateStatisticsEnabled.ToString)

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")
Write-Host "Automatically create statistics =" $db.AutoCreateStatisticsEnabled
Write-Host "Automatically update statistics =" $db.AutoUpdateStatisticsEnabled
