13. XML Enables SQL Server to be a Complete Data PlatformExploit the XML Capabilities of SQL Server 2005 by Jason Follas

14. Act I

15. Today's data world is full of XML-based data sources

16. <XML> Every database developer should be able to move data into and out of XML SQL

17. XML translation in middle-tier can be inflexible and may even increase network overhead

18. Move XML handling into the database to improve overall integration

19. Utilize SQL Server 2005 for database solutions that need to use XML data <XML>

20. Act II, Scene 1

21. Interpret XML as More Than Just Text Using the XML Data Type

22. XML is a First-Class Citizen data type INT DATETIME VARCHAR XML

23. Used in columns, variables, parameters, and return types

24. Serialize to and parse from string representation

25. Full support for typed XML using Schema

26. Has methods that offer inspection and extraction of data from the XML

27. exist()

28. query() and value()

29. nodes()

30. XML columns can be indexed for faster access to the contained data

31. Primary XML Index

32. Secondary XML Indexes (value, path, property)

33. Examples of when a secondary should be considered

34. demo

35. Act II, Scene 2

36. Harness the Data in XML Using the XQuery Language

37. Path expressions

38. Location steps

39. Attributes

40. Predicates

41. FLWOR statement FORLETWHEREORDER BYRETURN

42. For and Return

43. Where

44. Order By

45. XQuery Functions

46. Data Accessor Functions string() and data()

47. Functions that act on data (numeric, string, context, aggregate functions)

48. SQL Server Extension Functions sql:column() and sql:variable()

49. demo

50. Act II, Scene 3

51. Create XML From Relational Data Using the FOR XML Clause

52. Return XML from queries instead of rowsets <XML> SQL

53. RAW Mode SELECT * FROM Employee FOR XML RAW('Employee') <Employee EmployeeID="2" Federal_ID="000-00-0001" Name="Andrew Miller" DOB="1968-05-01T00:00:00" StartDate="2000-01-01T00:00:00" ManagerFK="3" /> <Employee EmployeeID="3" Federal_ID="000-00-0002" Name="Bert Parkins" DOB="1947-12-31T00:00:00" StartDate="2000-01-01T00:00:00" />

54. AUTO Mode SELECT * FROM Employee FOR XML AUTO <Employee EmployeeID="2" Federal_ID="000-00-0001" Name="Andrew Miller" DOB="1968-05-01T00:00:00" StartDate="2000-01-01T00:00:00" ManagerFK="3" /> <Employee EmployeeID="3" Federal_ID="000-00-0002" Name="Bert Parkins" DOB="1947-12-31T00:00:00" StartDate="2000-01-01T00:00:00" />

55. Nested FOR XML Queries SELECT [EmployeeID], [Name], ( SELECT [EmployeeID], [Name] FROM [Employee] WHERE ManagerFK = E.EmployeeID FOR XML AUTO, TYPE ) DirectReports FROM [Employee] E FOR XML RAW('Employee') <Employee EmployeeID="2" Name="Andrew Miller"> <DirectReports> <Employee EmployeeID="5" Name="Dave Murrel" /> </DirectReports> </Employee> <Employee EmployeeID="3" Name="Bert Parkins"> <DirectReports> <Employee EmployeeID="2" Name="Andrew Miller" /> <Employee EmployeeID="4" Name="Brad Barnes" /> </DirectReports> </Employee>

56. Control the structure of the resulting XML

57. PATH Mode

58. TYPE Mode

59. EXPLICIT Mode

60. Add necessary complexity to the resulting XML

61. NULL values and XSINIL

62. Generate Schemas

63. Adding Namespaces

64. demo

65. Does moving XML handling into the database improve overall design?

66. Act III

67. Developers unaware of SQL Server’s XML abilities are doing extra work

68. Utilize SQL Server 2005 for database solutions that need to use XML data <XML>

69. XML enables SQL Server to be a complete Data Platform

70. XML and SQL Server – A Great Combination
