建立、改變和移除結構描述
範例
如果要使用所提供的任何程式碼範例，您必須選擇用於建立應用程式的程式設計環境、程式設計範本和程式設計語言。如需詳細資訊，請參閱＜如何：在 Visual Studio .NET 中建立 Visual Basic SMO 專案＞或＜如何：在 Visual Studio .NET 中建立 Visual C# SMO 專案＞。
在 Visual Basic 中建立、改變和移除結構描述
此程式碼範例示範如何建立結構描述，並將其指派給資料庫物件。程式接著會授與權限給使用者，然後再於結構描述中建立新的資料表。
'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
'Define a Schema object variable by supplying the parent database and name arguments in the constructor.
Dim sch As Schema
sch = New Schema(db, "MySchema1")
sch.Owner = "dbo"
'Create the schema on the instance of SQL Server.
sch.Create()
'Define an ObjectPermissionSet that contains the Update and Select object permissions.
Dim obperset As ObjectPermissionSet
obperset = New ObjectPermissionSet()
obperset.Add(ObjectPermission.Select)
obperset.Add(ObjectPermission.Update)
'Grant the set of permissions on the schema to the guest account.
sch.Grant(obperset, "guest")
'Define a Table object variable by supplying the parent database, name and schema arguments in the constructor.
Dim tb As Table
tb = New Table(db, "MyTable", "MySchema1")
Dim mycol As Column
mycol = New Column(tb, "Date", DataType.DateTime)
tb.Columns.Add(mycol)
tb.Create()
'Modify the owner of the schema and run the Alter method to make the change on the instance of SQL Server.
sch.Owner = "guest"
sch.Alter()
'Run the Drop method for the table and the schema to remove them.
tb.Drop()
sch.Drop()
