Alter 方法 (TimeSpan)

更新 SQL Server 的实例上的任何 Database 对象属性更改。 

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

语法

声明
Public Sub Alter ( _
    transactionTerminationTime As TimeSpan _
)
用法
Dim instance As Database
Dim transactionTerminationTime As TimeSpan

instance.Alter(transactionTerminationTime)
public void Alter(
    TimeSpan transactionTerminationTime
)
public:
void Alter(
    TimeSpan transactionTerminationTime
)
member Alter : 
        transactionTerminationTime:TimeSpan -> unit 
public function Alter(
    transactionTerminationTime : TimeSpan
)

参数

  • transactionTerminationTime
    类型:System. . :: . .TimeSpan
    一个 TimeSpan 对象值,该值指定在使用 Alter 方法使属性更改持久化之前允许完成事务的时段。

注释

The Alter method updates any changes that have been made to the properties of the Database object since the Database object was created or since the last Alter statement. The modifications are combined and sent to the instance of SQL Server in a single network trip.

示例

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Define a Database object variable by supplying the server and the database name arguments in the constructor.
Dim db As Database
db = New Database(srv, "Test_SMO_Database")
'Create the database on the instance of SQL Server.
db.Create()
'Reference the database and display the date when it was created.
db = srv.Databases("Test_SMO_Database")
Console.WriteLine(db.CreateDate)
'Remove the database.
db.Drop()

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database($srv, "Test_SMO_Database")
$db.Create()
Write-Host $db.CreateDate
$db.Drop()
