  1. The Grand Tour SQL Server 2012 Brian Garraty @NULLgarity

  2. Who I am • SQL Server DBA • Virginia Beach Public Schools • MCITP DBA • HRSSUG Leadership Team • Prior Life: C++/VB Developer

  3. Itinerary – Part 1 • Functional yet Elegant • The Workshop • Modern Luxuries • Home Security

  4. Itinerary – Part 2 • Available Now • Bells & Whistles • Negotiations • The Small Print

  5. My Promise • I will aim to • Refrain from any marketing babble • Refrain from use of unneeded buzzwords • Not use any of the following expressions: • Mission Critical Confidence • Breakthrough Insight • Cloud on Your Terms

  6. Disclaimers • Not yet running 2012 in Production • High Level • No demos • We won’t cover everything • Very light on • BI • Cloud

  7. Historical Perspective • 7.5 (1998) • Architecture Improvements • Scalability • 2000 • Rewrite from Sybase • OLAP, ETL • Clustering • XML

  8. Historical Perspective • 2005 • Manageability (DMVs) • Performance (CLR, Partitioning) • High Availability (Mirroring) • 2008 (continue prior momentum) • Manageability (PBM) • Performance (Compression)

  9. Historical Perspective • 2008 R2 • PowerPivot • Report Builder 3.0 • Master Data Services • Azure (2010) • SQL as a Service

  10. Historical Perspective • 2012 (My Take) • Customer Feedback Driven • Showstopper Breakthroughs • Azure into the Fold

  11. Functional Elegance Your T-SQL can T-Sizzle...

  12. Logical Functions • CHOOSE • ( index, val_1, val_2 [, val_n ] ) • IIF • ( boolean_expression, true_value, false_value )

  13. String Functions • CONCAT • ( string_value1, string_value2 [, string_valueN ] ) • FORMAT • ( value, format [, culture ] )

  14. Conversion Functions • PARSE • ( string_value AS data_type [ USING culture ] ) • TRY_CAST • ( expression AS data_type [ ( length ) ] ) • TRY_CONVERT • ( data_type [ ( length ) ], expression [, style ] ) • TRY_PARSE

  15. Date and Time Functions • DateFromParts • ( year, month, day ) • DateTime2FromParts • ( year, month, day, hour, minute, seconds, fractions, precision ) • EOMonth • ( start_date [, month_to_add ] )

  16. EXECUTE … WITH RESULTS • UNDEFINED – any or none • NONE –abort if results returned • <result_sets_definition> • Describes explicit result set(s) • A step towards contract or interface • Useful in SSIS OLEDB source

  17. EXECUTE … WITH RESULTS EXECuspGetEmployeeManagers16 WITHRESULTSETS ( ([Reporting Level]intNOTNULL, [ID of Employee]intNOTNULL, [Employee First Name]nvarchar(50)NOTNULL, [Employee Last Name]nvarchar(50)NOTNULL, [Employee ID of Manager]nvarchar(50)NOTNULL, [Manager First Name]nvarchar(50)NOTNULL, [Manager Last Name]nvarchar(50)NOTNULL) );

  18. Sequence Numbers • Similar to IDENTITY • Not tied to table • Controlled by application • NEXT VALUE FOR

  19. Sequence Use Cases • Default value for columns • Concatenated value identity • Cross statement ROW_NUMBER()

  20. THROW • Raises exception, invokes CATCH block • If outside TRY…CATCH, ends session with severity 16 • Simpler than RAISEERROR • Useful inside CATCH blocks

  21. Metadata Discovery • SET FMTONLY Deprecated • sp_describe_first_result_set • @tsql= N'Transact-SQL_batch • @params = N'parameters' • @browse_information_mode = <tinyint> • Also via similar DMFs

  22. The Workshop Everything you need to get ‘er done...

  23. SSMS Changes • “Powered by” Visual Studio 2010 • F5 is the new Ctrl-E (aargh!) • Result grid columns rearrangable • Editor windows are draggable

  24. More SSMS Changes • Restore GUI enhancements • Page Restore GUI • Database Engine Tuning Advisor • Query Plan Cache Workload • Top 1,000 events by default

  25. Most Unsettling SSMS Change • No Support for Legacy File Extensions • .PRC • .TAB • .UDF • etc

  26. IntelliSense Improvements • Code Snippets • Templates integrated with IntelliSense • Customizable • Surround With • BEGIN…END • IF • WHILE

  27. Documentation Changes • Menu reads SQL Server Documentation • Defaults to Online help • Local installs separately • Same viewer as Visual Studio 2010 SP1

  28. LocalDB • Dev-targeted Edition of Express • Runs in User Mode • “SQL Express-Lite” • Fast, zero-config install • Fewer pre-requisites

  29. Automatic LocalDB Instances • Public • Created and managed automatically • Usable by any app • Exists if LocalDB exists

  30. Named LocalDB Instances • Private • Created, owned, managed by app • Isolated, dedicated

  31. Shared LocalDB Instances • Support multiple users • Created by administrator • Either automatic or named

  32. SSIS Changes • “Largest investment in SSIS to date”

  33. SSIS Paradigm Shift 2.0 • Project Concept • Buildable • Deployable • Manageable • Best practice acknowledgement

  34. SSIS Projects • Shared Connection Managers • Project scoped variables • Optional

  35. SSIS Parameters • Replace configurations • Project or Package Level • Package-scoped recognized by EPT

  36. SSIS Dev Changes • SQL Server Data Tools is the new BIDS • Undo • Consistency in XML

  37. Modern Luxuries Granite countertops coated in PowerShell...

  38. Columnstore Index • Turbo button for typical DW queries • Columnar (versus row based) data format • Speed from • Less data read, only columns • Columns are heavily compressed • Typical query uses few columns • Columns are processed in chunks • Limitations • Read only • One per table

  39. Extended Events • Wizard-driven Creation • GUI-driven Editor • Customizable Data Viewer

  40. PowerShell • Increasingly used for SQL Management • AlwaysOn • SSIS • No longer installed by SQL Setup • SQLPS Now Deprecated • Stick with SQLPSX & straight up PowerShell

  41. Home Security For that peaceful, easy feeling...

  42. More Secure by Default • No auto provisioning to sysadmin • BUILTIN\Administrators • Local System

  43. Managed Service Accounts • Created & managed by Domain Controller • Passwords • SPNs • Domain\Accountname$ • Windows Server 2008 R2 only

  44. Virtual Accounts • Automatically managed local accounts • No Passwords • NT SERVICE\<SERVICENAME> • Access to network via computer account • <domain_name>\<computer_name>$ • Windows Server 2008 R2 only

  45. Contained Databases • Little or no server dependencies • Contained vs. uncontained objects • Useful for • Failover • SQL Azure • Non sysadmin Administration

  46. Audit Improvements • Server level supported in all editions (database level still Enterprise-only) • Recoverable audit log failures • User defined audits • Audit log filters (WHERE clause)

  47. Other Security • User-defined server roles • Default schema for Windows Groups • New encryption algorithm support • SHA2_256 • SHA2_512 • Stronger Server & Database Master Key Encryption (3DES to AES)

  48. Available Now Move in ready!!!

  49. High Availability • AlwaysOn – umbrella term • Failover Cluster Instances • Availability Groups • Online Operations • Indexes with LOBs • Adding Columns with Default Values

  50. Failover Cluster Instances • Multi-subnet Failover Clusters • Inter-datacenter • No single, shared storage • Data replication • Disaster recovery + HA
