1. BARBARIN DAVID SQL Server Senior Consultant Pragmantic SQL Server Denali : New development features

2. David BARBARIN david.barbarin@pragmantic.com SQL Server Senior Consultant at Pragmantic SA Collaborative solutions Business solutions Data Management and Business Intelligence

3. Unstructured data and FILETABLE

4. The FileTable feature builds on top of the SQL Server FILESTREAM technology Represent a hierarchy of folders and file storage Non transactional access Can be used by Windows applications without changes FILETABLE

5. A row in a FileTable contains : A FILESTREAM column for stream data and a file_id (GUID) identifier. (NULL if a directory is concerned) Both path_locator and parent_path_locator columns 10 file attributes such as created date and modified date that are useful with file I/O APIs A type column that supports full-text search and semantic search over files and documents. A FileTable enforces certain system-defined constraints and triggers to maintain file namespace semantics. When the database is configured for non-transactional access, directory and files can be access by the filestream network share name FILETABLE

7. FullText search and semantic search

8. Semantic search builds upon the existing full-text search feature in SQL Server but enables new scenarios that extend beyond syntactical keyword searches Full-text search lets you query the words in a document Semantic search lets you query the meaning of the document Semantic search

9. Before you can use Semantic Search, you have to install, attach, and register the Semantic database. This database contains the statistical language models required by semantic search Don’t forget to install the Latest Filters to allow indexing the concerned documents Semantic search

10. Property Search is possible in the documents. The result depends directly on the I-filters. Customizable NEAR (CONTAINS(column_name, 'NEAR((John, Smith),2)') ) Update of all word breakers and stemmers used by Full-Text Search except to Korean language FullText search

11. Meta Data Discovery

12. SET FMT ONLY will be replaced by sys.sp_describe_first_result_set sys.dm_exec_describe_first_result_set sys.dm_exec_describe_first_result_set_for_object Meta Data Discovery

13. Metada Discovery demo…

14. Ad-hoc Query Paging

15. Paging still exists in SQL Server by using different methods Implementation of paging like “MySQL” simplifies the search of a range of values ORDER BY clause has been enhanced with OFFSET and FETCH NEXT … ROWS ONLY options Ad-hoc Query Paging

16. ORDER BY, OFFSET and FETCH demo…

17. Execute statement enhanced

18. The EXECUTE statement can now specify the metadata returned from the statement by using the WITH RESULT SETS argument Allow the encapsulation of a stored procedure. Can be a contract between a stored procedure and the Direct Access Layer of an application Change in the stored procedure doesn’t not imply change on the DAL Select data doesn’t require anymore a temp table Conversion with SSIS source and destination is simplier Execute statement

19. demo…

20. Sequence objects

21. Sequences are now possible with SQL Server 2012. A Sequence object is a user-defined schema-bound object. It operates similar to an identity column, but sequence numbers are not restricted to use in a single table The last-used value is stored in memory CREATE SEQUENCE and NEXT VALUE FOR Sequences

22. demo…

23. THROW statement

24. Like Csharp or other language THROW raises an exception and transfers execution to a CATCH block of a TRY…CATCH construct THROW does not need a predefined message in sys.messages to work unlike RAISERROR It's not possible to redefine the severity by THROW (always 16) unlike RAISERROR Throw statement

25. demo…

26. T-SQL enhancements

27. Conversion functions PARSE TRY_PARSE TRY_CONVERT T-SQL enhancements

28. Date and time functions DATEFROMPARTS DATETIME2FROMPARTS DATETIMEFROMPARTS DATETIMEOFFSETFROMPARTS SMALLDATETIMEFROMPARTS TIMEFROMPARTS EOMONTH T-SQL enhancements

29. Logical functions CHOOSE IIF T-SQL enhancements

30. String functions CONCAT FORMAT T-SQL enhancements

31. Logarithm computing : SQL Server supported only two functions that compute logarithms: LOG (for natural logarithm) and LOG10 (for logarithm with a base of 10). LOG function is modified with a second optional option : base that allows to compute a LOG with an another base SELECT LOG(256, 2) equivalent to SELECT LOG(256) / LOG(2); T-SQL enhancements

32. New Analytic Functions are added CUM_DIST() PERCENTILE_CONT() PERCENTILE_DISC() PERCENTILE_RANK() FIRST_VALUE() LAST_VALUE() LEAD() LAG() T-SQL enhancements

33. demo…

34. UTF-16 Supplementary Characters (SC) Collations SC collations can improve searching and sorting by functions that use the Unicode types nchar and nvarchar UTF16 Support Collations

35. New methods for geometry and geography data types that work with circular arc segments New static aggregate methods for geometry data type and geography data type Spatial types

36. SQL Server Developer Tools

37. Juneau provides a unified set of tools that combines : the projects found in SQL Server Business Intelligence Design Studio - including projects of Integration Services, Analysis and Reporting the project database SQL Server. SSDT (Juneau Project)

38. SQL Server Developer Tools demo…
