How to: Set Up a Partition Scheme for a Table in Visual Basic .NET

업데이트: 2005년 12월 5일

This section describes how to create a partition scheme for a table in using Visual C# .NET.

The code example shows how to create a partition function and a partition scheme for the TransactionHistory table in the AdventureWorks sample database. The partitions are divided by date with the intention of separating out old records into the TransactionHistoryArchive table.

Setting up a Partition Scheme for a Table

  1. Start Visual Studio 2005.

  2. On the File menu, select New Project. The New Project dialog box appears.

  3. In the Project Types pane, select Visual Basic. In the Templates pane, select Console Application.

  4. (Optional) In the Name box, type the name of the new application.

  5. Click OK to load the Visual Basic console application template.

  6. On the Project menu, select Add Reference item. The Add Reference dialog box appears. Select Browse and locate the SMO assemblies in the C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies folder and select the following files:

    Microsoft.SqlServer.ConnectionInfo.dll

    Microsoft.SqlServer.Smo.dll

    Microsoft.SqlServer.SqlEnum.dll

    Microsoft.SqlServer.SmoEnum.dll

  7. On the View menu, click Code.-Or-Select the Module1.vb window to display the code window.

  8. In the code, before any declarations, type the following Imports statements to qualify the types in the SMO namespace.

    Imports Microsoft.SqlServer.Management.Smo
    Imports Microsoft.SqlServer.Management.Common
    
  9. Insert the code below into the main program.

  10. Run and build the application.

'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 and create three new file groups on the database.
Dim fg2 As FileGroup
fg2 = New FileGroup(db, "Second")
fg2.Create()
Dim fg3 As FileGroup
fg3 = New FileGroup(db, "Third")
fg3.Create()
Dim fg4 As FileGroup
fg4 = New FileGroup(db, "Fourth")
fg4.Create()
'Define a partition function by supplying the parent database and name arguments in the constructor.
Dim pf As PartitionFunction
pf = New PartitionFunction(db, "TransHistPF")
'Add a partition function parameter that specifies the function uses a DateTime range type.
Dim pfp As PartitionFunctionParameter
pfp = New PartitionFunctionParameter(pf, DataType.DateTime)
pf.PartitionFunctionParameters.Add(pfp)
'Specify the three dates that divide the data into four partitions.
Dim val() As Object
val = New Object() {"1/1/2003", "1/1/2004", "1/1/2005"}
pf.RangeValues = val
'Create the partition function.
pf.Create()
'Define a partition scheme by supplying the parent database and name arguments in the constructor.
Dim ps As PartitionScheme
ps = New PartitionScheme(db, "TransHistPS")
'Specify the partition function and the filegroups required by the partition scheme.
ps.PartitionFunction = "TransHistPF"
ps.FileGroups.Add("PRIMARY")
ps.FileGroups.Add("second")
ps.FileGroups.Add("Third")
ps.FileGroups.Add("Fourth")
'Create the partition scheme.
ps.Create()
