  2. They say: A picture is worth a thousand words

  3. We say: A demo is worth a thousand slides 

  4. Programmability .NET Framework Integration Stored Procedures User Defined Types Aggregates Web Services Support XML Support Summary Agenda

  5. Programming environment for Functions, Stored Procedures, Triggers User Defined Types, Aggregates In-Proc Data Access (ADO.NET V2) Symmetric data access Mid-tier/data tier deployment decision Security Integration of SQL and CLR security Three levels of code access security Safe, External-Access (verifiable), Unsafe Tight integration with Visual Studio Authoring, debugging, deployment, & profiling .NET Framework Integration

  6. VB,C#,C++ Build Assembly: “TaxLib.dll” SQL Data Definition: create assembly … create function … create procedure … create trigger … create type … SQL Queries: select sum(tax(sal,state)) from Emp where county = ‘King’ SQL Server The Developer Experience VS .NET Project Runtime hosted by SQL (in-proc)

  7. Server debug integration Set breakpoints anywhere Full debugger visibility Single step support: Between languages: T-SQL, C#, VB, & C++ Between deployment tiers: E.g. Mid-tier, through SQL Server stored proc call & back to mid-tier Authoring/Debugging/Deploying

  8. Choice of where to run logic Database, for logic that runs close to data Mid-tier, for logic that scales out Symmetric programming model Leverage skills mid-tier & server Choice of programming language C#, VB.NET, & Managed C++, for a safe, modern execution environment T-SQL continues to be supported & enhanced Remains good choice for data-intensive procedures Safe extended stored proc replacement .NET Integration Choices

  9. CLR Integration DemoStored ProceduresUser Defined TypesAggregates

  10. SQL & stored proc calls via HTTP/SOAP Easy, standards based connectivity from Unix platforms to SQL Server Provides native HTTP listening HTTP endpoint specifying URL, port, reqs Publish WSDL for endpoints Standard-based SOAP 1.1 and 1.2, WSDL 1.1, inlined XSD Windows and SQL authentication (SSL only) Stored Proc can return result as DataSet Compatible with mid-tier prog. model HTTP/SOAP Features

  11. SOAP Demo

  12. XML data type & XML index support Unified XML & relational store Both SQL & XQuery supported by same industrial strength infrastructure Leverages existing SQL engine & optimizer XQuery with data modification extensions XML views Declarative Mapping Files XML schema enforcement Client access using ADO.NET & SOAP XML Support

  13. XML data type Native SQL type Use for column, variable or parameter CREATE TABLE docs (id INT PRIMARY KEY, xDoc XML NOT NULL) Store un-typed or typed XML instances Well-formed and validation checks Methods on XML data type Query(), value(), exist() & modify() Native XML Store

  14. Create XML index on XML column CREATE XML INDEX idx_1 ON docs (xDoc) Creates indexes on tags, values & paths Speeds up queries Entire query is optimized Same award winning cost based optimizer Indexes are used as available XML Indexes

  15. XML Demo
