How to: Run Database Integrity Checks in Visual Basic .NET

  • Article

This section describes how to run consistency checking on a database by using Visual Basic .NET.

Microsoft SQL Server provides data integrity checking. This code example runs a database consistency type check on the specified database. In this example CheckTables is used, but CheckAllocations, CheckCatalog, or CheckIdentityValues can be used similarly.

Note

The StringCollection object requires a reference to the namespace using the imports System.Collections.Specialized statement.

Running database integrity checks

  1. Start Visual Studio 2005.

  2. From 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. 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 that follows this procedure into the main program.

  10. Run and build the application.

Example

'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")
'Note, to use the StringCollection type the System.Collections.Specialized system namespace must be included in the imports statements.
Dim sc As StringCollection
'Run the CheckTables method and display the results from the returned StringCollection variable.
sc = db.CheckTables(RepairType.None)
Dim c As Integer
For c = 0 To sc.Count - 1
    Console.WriteLine(sc.Item(c))
Next
