1. Re-inventing query language Ruslan Zakirov < [email_address] > YAPC::EU Aug 2009

2. Queries

3. Queries select * from U where ...

4. Queries SQL

5. Queries S...? Query Language

6. SQL Simple?

7. SQL Small?

8. SQL Solid?

9. SQL What does S. stand for?

10. SQL (may be) Stupid

11. SQL (may be) Suckish

12. Jifty::DBI

13. Jifty::DBI ORM for Jifty

14. Jifty::DBI Records Collections

15. tisql

16. tisql ti-skull

17. tisql Query Language

18. tisql String-centric

19. Why string? Serialization

20. Why string? Typing

21. Why string? CLI

22. Why string? API

23. Syntax basics

24. Basics .foo = 'str' OR ( .baz > 10 )

25. Basics AND OR ( ) ' &quot;

26. Basics [!]=, [><]=? [NOT] LIKE IS [NOT] NULL

27. Jifty::DBI Relations

28. Jifty::DBI (relations) refers to Foo [by a_column]

29. Jifty::DBI (relations) refers_to FooCollection by a_column

30. Jifty::DBI (relations) Named

31. tisql relations .foo.bar.baz = 'x'

32. tisql relations .tags.used_by.id = $id

33. tisql relations .tag.value != 'foo'

34. Operation Modifiers

35. Operation Modifiers has has no

36. Operation Modifiers has [no] .foo.bar <=> .foo.bar.id is [not] null

37. Operation Modifiers has no .foo.bar = 'baz' <=> .foo.bar != 'baz'

38. Operation Modifiers has no .foo.bar != 'baz' has .foo.bar != 'baz'

39. No joins!?

40. [no] joins column foo => refers_to Foo

41. [no] joins … by tisql '...'

42. [no] joins column attrs =>... by tisql &quot;attrs.model = 'User' AND attrs.record = .id&quot;

43. Combining things

44. Combining .members.first = 'John' AND .members.last = 'Doe'

45. Combining (John Doe) (John S., D. Doe)

46. Combining 1. Aliases

47. Combining FROM .members AS member WHERE member.first = 'John' AND member.last = 'Doe'

48. Combining 2. Placeholders

49. Combining column members => … by tisql ' … AND members.first = %f '

50. Combining has .members {first => 'John'} {last => 'Doe'}

51. Combining Idea! Any column!

52. Strings suck

53. Quote

54. API

55. API binding

56. API ->tisql('.foo = ?', «bar»);

57. API Q and C functions

58. API overload

59. API Q(...) | Q(...) Q(...) & Q(...)

60. Boring

61. Other Query Languages

62. Other QLs from:john (to:me OR cc:me) asshole

63. Other QLs Parse

64. Other QLs Parse ::BooleanLogic

65. Other QLs callbacks based

66. Other QLs default struct

67. Other QLs processing

68. Cool things

69. cool things joins bundling

70. cool things (tag:foo OR tag:bar) tag:zoo

71. cool things joins merging

72. cool things .a.b.c.col = 'x' AND .a.b.c.d.col = 'y'

73. cool things subset extraction

74. cool things subject:x !tag:foo tag:bar

75. cool things subject:x

76. Where?

79. the:end

80. Questions?

81. Speak slow and loud

82. Not thaaaat slow
