Microsoft SQL Server 2005 Developer’s Guide- P48 pptx

Chapter 12: Developing with SMO 449 To refer to the first database object by ordinal number, you use the following code: Dim oServerConn As ServerConnection = New ServerConnection() oServerConn.ServerInstance = "SQL2005" oServerConn.LoginSecure = True Dim oSQLServer As New Server(oServerConn) oSQLServer.Databases(0) Again, this code implicitly uses the Item method of the Databases collections. In this case, the Item method is passed the first ordinal value, instead of a string containing the name of the database. The ordinal value of 0 returns the first database in the oSQLServer object. Similarly, the ordinal value of 1 returns the second database, and so on. SMO Hierarchy The SMO object model extends and supplants its predecessor, the SQL-DMO object model. Unlike the SQL-DMO object framework, which was based on COM, the newer SMO object model is based on the .NET framework. This means that SMO requires the .NET framework to be installed on the systems that are used to run SMO management applications. SMO can be used to manage SQL Server 7 and SQL Server 2000, as well as SQL Server 2005, allowing you to easily manage a multiversion environment. SQL-DMO will also continue to be supported by SQL Server 2005, allowing backward compatibility for your applications, but SQL-DMO has not been enhanced to include the new features found in the new release. In other words, SQL-DMO is limited to supporting only those features that were found in the previous releases of SQL Server. The new SMO object framework contains over 150 new classes, enabling your custom management application to take advantage of the new features found in SQL Server 2005. The SMO object model consists of a hierarchy of objects contained in several namespaces and .dll files. The different SMO namespaces represent different areas of functionality within SMO. Table 12-2 lists the namespaces and their relative functionality. The core SMO namespace, Microsoft.SqlServer.Management.Smo, is implemented as a .NET assembly. This means that the Common Language Runtime (CLR) must be installed before using the SMO objects. The main SMO namespace contains classes that are divided into two categories: instance classes and utility classes. 450 Microsoft SQL Server 2005 Developer’s Guide Utility Classes The utility classes in SMO provide programmatic control over certain SQL Server objects and perform specific tasks, such as backup and restore, and transfer of schema and data. The utility classes are shown here: ᭤ Backup Provides programmatic access to SQL Server backup operations. ᭤ BackupDevice Provides programmatic access to SQL Server backup devices. ᭤ BackupDeviceItem Provides programmatic access to named SQL Server backup devices. ᭤ BackupRestoreBase A base class that represents functionality that is common to both backup and restore operations. ᭤ DatabaseActiveDirectory Provides programmatic access to the Active Directory settings for a database. ᭤ FullTextService Allows programmatic access to the Search Full Text settings. ᭤ PartitionFunction Provides programmatic access to partition functions. ᭤ PartitionFunctionParameter Provides programmatic access to partition function parameters. ᭤ PartitionScheme Provides programmatic access to partition schemes. ᭤ PartitionSchemeParameter Provides programmatic access to partition scheme parameters. Table 12-2 SMO Namespaces Namespace Function Microsoft.SqlServer.Management.Smo Contains instance classes, utility classes, and enumerations that are used to programmatically control SQL Server. Microsoft.SqlServer.Management.Common Contains the classes that are common to Replication Management Objects (RMO) and SMO. Microsoft.SqlServer.Management.Smo.Agent Contains classes that represent the SQL Server Agent. Microsoft.SqlServer.Management.Smo.Wmi Contains classes that represent the WMI Provider. Microsoft.SqlServer.Management.Smo.RegisteredServers Contains classes that represent Registered Server. Microsoft.SqlServer.Management.Smo.Mail Contains classes that represent Database Mail. Microsoft.SqlServer.Management.Smo.Broker Contains classes that represent the Service Broker. Microsoft.SqlServer.Management.Smo.NotificationServices Contains classes that represent Notification Services. Chapter 12: Developing with SMO 451 ᭤ ProgressReportEventArgs Provides programmatic access to the arguments used to report the progress of an operation that works through an object hierarchy, such as discovering dependencies in scripting operations. ᭤ Property Provides programmatic access to the properties of SMO objects. ᭤ Protocol Provides programmatic access to the protocols supported by SQL Server. ᭤ RelocateFile A programmatic tool that allows an .mdf or .ldf fi le to be relocated. ᭤ Restore Provides programmatic access to restore operations. ᭤ Rule Provides programmatic access to a SQL Server rule. ᭤ Scripter The overall, top-level object for managing scripting operations. ᭤ ScriptingErrorEventArgs Provides programmatic access to the arguments used to report the errors that occur during scripting operations. ᭤ ScriptingOptions Provides programmatic options to the options that can be set for scripting operations. ᭤ ServerActiveDirectory Provides programmatic access to Active Directory functionality. ᭤ ServerEventArgs Provides programmatic access to the arguments used to report all types of events that occur on an instance of SQL Server. ᭤ SmoEventArgs Provides programmatic access to the arguments used to report the events that occur in SMO applications. ᭤ SoapMethodCollectionBase A base class that is inherited by the SoapMethodCollection class and provides programmatic access to the collection of SOAP methods that exist in the SOAP confi guration. ᭤ SoapMethodObject A base class that is inherited by the SoapMethod class and provides programmatic access to the referenced SOAP method. ᭤ TcpProtocol Provides programmatic access to the protocols supported by SQL Server. ᭤ Transfer A tool object that provides programmatic control over copying of schemas and data to other instances of SQL Server. ᭤ Urn Provides programmatic access to Uniform Resource Name (URN) addresses that uniquely identify SQL Server objects. ᭤ VerifyCompleteEventArgs Provides programmatic access to the arguments used to report the details of the event that occurs when a backup verifi cation operation completes. 452 Microsoft SQL Server 2005 Developer’s Guide Instance Classes The instance classes embody SQL Server objects such as servers, databases, and tables and are organized into a hierarchical format. NOTE An important optimization that SMO has over SQL-DMO is called delayed instantiation. As your applications run, SMO retrieves the objects and properties only as they are needed. Unlike SQL-DMO, which gets everything up front, instead SMO makes many small round-trips to the server. SMO also lets you prefetch collections and retrieve objects using predefined properties. This lets you have control over SMO’s behavior as you build applications. SMO Server Object Hierarchy The Server object is the primary SMO object.
