1 Building Management Applications with SQL Server “Yukon” SQL Management Objects (SMO): Overview Bruce Prang Development Manager Microsoft Corporation Bruce Prang Development Manager Microsoft Corporation Session Code: DAT360

2 What is SMO SQL Server Management Objects Programmatic object model for DDL operations Use it for creation, management, discovery, configuration of Sql Servers.NET Class Library Not a total abstraction of Sql Server SQL Server Management Objects Programmatic object model for DDL operations Use it for creation, management, discovery, configuration of Sql Servers.NET Class Library Not a total abstraction of Sql Server

3 Some of the Design Goals 100% coverage of Sql Server features Improve scalability and performance Simple to use, but rich object model High level of control over object model behavior Advanced scripting capabilities Build SQL Server Workbench on it 100% coverage of Sql Server features Improve scalability and performance Simple to use, but rich object model High level of control over object model behavior Advanced scripting capabilities Build SQL Server Workbench on it

7 SMO Features Optimized instantiation of objects Scripting – Basic and Advanced Capture of Transact-SQL Support for new Yukon features Use of.NET types E.g. DateTime, Timespan instead of scaled long integers, etc. Management Object Model for SQL Services and Configuration (through WMI Provider) Optimized instantiation of objects Scripting – Basic and Advanced Capture of Transact-SQL Support for new Yukon features Use of.NET types E.g.

8 Feature Overview Optimized Instantiation Instance Classes support “optimized (delayed) instantiation” Object states 1: Partially instantiated (some properties available) 2: Fully instantiated Full instantiation is triggered when a property is called that has not been retrieved yet, or when a method is called that requires a missing property Instance Classes support “optimized (delayed) instantiation” Object states 1: Partially instantiated (some properties available) 2: Fully instantiated Full instantiation is triggered when a property is called that has not been retrieved yet, or when a method is called that requires a missing property

9 Feature Overview Optimized Instantiation Can be controlled by programmer DefaultInitFields, PrefetchObjects Fits any scenario Can be controlled by programmer DefaultInitFields, PrefetchObjects Fits any scenario Memory optimal Network/Query optimal Delayed instantiation per object [default] Many objects fully initialized

11 Feature Overview Capture Mode All Transact-SQL generated by performing actions on SMO objects can be captured or recorded This is NOT transactional, it is only capture WorkBench Dialogs use this capability to script operations All Transact-SQL generated by performing actions on SMO objects can be captured or recorded This is NOT transactional, it is only capture WorkBench Dialogs use this capability to script operations

12 Feature Overview Scripter Class Basic Scripting All DMO Scripting options will continue to be supported Script interface on individual classes will also be available (same as SQL-DMO) Advanced Scripting Filtering, available in multiple places List modification Object modification Progress and Error events Basic Scripting All DMO Scripting options will continue to be supported Script interface on individual classes will also be available (same as SQL-DMO) Advanced Scripting Filtering, available in multiple places List modification Object modification Progress and Error events

15 How Did We Get Here? SQL Server 6.x– SQLOLE SQL Server 7.0– SQL-DMO SQL Server 2000– SQL-DMO SQL Server Yukon– SMO Architectural limitations in DMO Needed a.Net class library Needed Full Support in object model SQL Server 6.x– SQLOLE SQL Server 7.0– SQL-DMO SQL Server 2000– SQL-DMO SQL Server Yukon– SMO Architectural limitations in DMO Needed a.Net class library Needed Full Support in object model

16 Backwards Compatible SMO Supports SQL Server 7.0 SQL Server 2000 SQL Server “Yukon” COM callable wrappers for Script DMO “Yukon” Shipping in the Yukon box Works against “Yukon” No new Yukon features SMO Supports SQL Server 7.0 SQL Server 2000 SQL Server “Yukon” COM callable wrappers for Script DMO “Yukon” Shipping in the Yukon box Works against “Yukon” No new Yukon features
