AlterWithNoCheck 方法
更新 SQL Server 的实例上的任何 Table 对象属性更改，且不首先检查属性值。
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 AlterWithNoCheck
用法
Dim instance As Table
instance.AlterWithNoCheck()
public void AlterWithNoCheck()
public:
void AlterWithNoCheck()
member AlterWithNoCheck : unit -> unit
public function AlterWithNoCheck()
注释
The AlterWithNoCheck method updates any changes that have been made to the Table object's properties since the Table 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 to the instance of SQL Server.
示例
The following code example shows how to create a new table, and then update it by using the AlterWithNoCheck method.
C#
Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2008R2"];
Table tb = new Table(db, "Test Table");
Column col1 = new Column(tb, "Name", DataType.NChar(50));
Column col2 = new Column(tb, "ID", DataType.Int);
tb.Columns.Add(col1);
tb.Columns.Add(col2);
tb.Create();
Column col3 = new Column(tb, "Date", DataType.DateTime);
tb.Columns.Add(col3);
tb.AlterWithNoCheck();
Powershell
#Connect to the local server and get the AdventureWorks2008R2 database
$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")
#Create the Table
$tb = new-object Microsoft.SqlServer.Management.Smo.Table($db, "Tester Table")
$col1 = new-object Microsoft.SqlServer.Management.Smo.Column($tb, "Name", [Microsoft.SqlServer.Management.Smo.DataType]::NChar(50))
$col2 = new-object Microsoft.SqlServer.Management.Smo.Column($tb, "ID", [Microsoft.SqlServer.Management.Smo.DataType]::Int)
$tb.Columns.Add($col1)
$tb.Columns.Add($col2)
$tb.Create()
#Add a new column and update the table
$col3 = new-object Microsoft.SqlServer.Management.Smo.Column($tb, "Date", [Microsoft.SqlServer.Management.Smo.DataType]::DateTime)
$tb.Columns.Add($col3)
#$tb.AlterWithNoCheck()
Write-Host $tb.Columns
$tb.Drop()
