The Small Print

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

Disclaimers

Not yet running 2012 in Production High Level No demos We won’t cover everything Very light on

BI Cloud

Historical Perspective

7.5 (1998) Architecture Improvements Scalability

2000 Rewrite from Sybase OLAP, ETL Clustering XML

Historical Perspective

2005 Manageability (DMVs) Performance (CLR, Partitioning) High Availability (Mirroring)

2008 (continue prior momentum) Manageability (PBM) Performance (Compression)

Historical Perspective

2008 R2 PowerPivot Report Builder 3.0 Master Data Services

Azure (2010) SQL as a Service

Historical Perspective

2012 (My Take) Customer Feedback Driven Showstopper Breakthroughs Azure into the Fold

Functional EleganceYour T-SQL can T-Sizzle...

Logical Functions

CHOOSE ( index, val_1, val_2 [, val_n ] )

IIF ( boolean_expression, true_value,

false_value )

String Functions

CONCAT ( string_value1, string_value2 [,

string_valueN ] )

FORMAT ( value, format [, culture ] )

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

Date and Time Functions

DateFromParts ( year, month, day )

DateTime2FromParts ( year, month, day, hour, minute,

seconds, fractions, precision )

EOMonth ( start_date [, month_to_add ] )

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

EXECUTE … WITH RESULTSEXEC uspGetEmployeeManagers 16WITH RESULT SETS(   ([Reporting Level] int NOT NULL,    [ID of Employee] int NOT NULL,    [Employee First Name] nvarchar(50 ) NOT NULL,    [Employee Last Name] nvarchar(50 ) NOT NULL,    [Employee ID of Manager] nvarchar(50 ) NOT NULL,    [Manager First Name] nvarchar(50 ) NOT NULL,    [Manager Last Name] nvarchar(50 ) NOT NULL ));

Sequence Numbers

Similar to IDENTITY

Not tied to table

Controlled by application NEXT VALUE FOR

Sequence Use Cases

Default value for columns

Concatenated value identity

Cross statement ROW_NUMBER()

THROW

Raises exception, invokes CATCH block

If outside TRY…CATCH, ends session with severity 16

Simpler than RAISEERROR

Useful inside CATCH blocks

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

The WorkshopEverything you need to get ‘er done...

SSMS Changes

“Powered by” Visual Studio 2010

F5 is the new Ctrl-E (aargh!)

Result grid columns rearrangable

Editor windows are draggable

More SSMS Changes

Restore GUI enhancements

Page Restore GUI

Database Engine Tuning Advisor Query Plan Cache Workload Top 1,000 events by default

Most Unsettling SSMS Change No Support for Legacy File

Extensions .PRC .TAB .UDF etc

IntelliSense Improvements Code Snippets

Templates integrated with IntelliSense Customizable

Surround With BEGIN…END IF WHILE

Documentation Changes

Menu reads SQL Server Documentation

Defaults to Online help

Local installs separately

Same viewer as Visual Studio 2010 SP1

LocalDB

Dev-targeted Edition of Express

Runs in User Mode

“SQL Express-Lite”

Fast, zero-config install

Fewer pre-requisites

Automatic LocalDB Instances Public

Created and managed automatically

Usable by any app

Exists if LocalDB exists

Named LocalDB Instances Private

Created, owned, managed by app

Isolated, dedicated

Shared LocalDB Instances Support multiple users

Created by administrator

Either automatic or named

SSIS Changes

“Largest investment in SSIS to date”

SSIS Paradigm Shift 2.0

Project Concept Buildable Deployable Manageable

Best practice acknowledgement

SSIS Projects

Shared Connection Managers

Project scoped variables

Optional

SSIS Parameters

Replace configurations

Project or Package Level

Package-scoped recognized by EPT

SSIS Dev Changes

SQL Server Data Tools is the new BIDS

Undo

Consistency in XML

Modern LuxuriesGranite countertops coated in PowerShell...

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

Extended Events

Wizard-driven Creation

GUI-driven Editor

Customizable Data Viewer

PowerShell

Increasingly used for SQL Management AlwaysOn SSIS

No longer installed by SQL Setup

SQLPS Now Deprecated Stick with SQLPSX & straight up

PowerShell

Home SecurityFor that peaceful, easy feeling...

More Secure by Default

No auto provisioning to sysadmin BUILTIN\Administrators Local System

Managed Service Accounts Created & managed by Domain

Controller Passwords SPNs

Domain\Accountname$ Windows Server 2008 R2 only

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

Contained Databases

Little or no server dependencies

Contained vs. uncontained objects

Useful for Failover SQL Azure Non sysadmin Administration

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)

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)

Available NowMove in ready!!!

High Availability

AlwaysOn – umbrella term Failover Cluster Instances Availability Groups

Online Operations Indexes with LOBs Adding Columns with Default Values

Failover Cluster Instances Multi-subnet Failover Clusters

Inter-datacenter No single, shared storage Data replication Disaster recovery + HA

FCI Flexible Failover Policy Upgrade from “SELECT @@SERVERNAME”

Windows uses dedicated connection

Health monitored via sp_server_diagnostics

Configurable Health Check Timeout

Configurable Failover Condition Level

FCI Failover Condition Level

0 – No automatic failover or restart 1 – On server down 2 – On server unresp0nsive 3 – On critical server errors 4 – On moderate server errors 5 – On qualified failure conditions,

e.g. SQL Service is down SQL Instance unresponsive etc

FCI Indirect Checkpoints

Checkpoints flush mods to disk

Impact recovery time on unexpected shutdown or failover

Normally target is server configuration

Database specific target

Tempdb on Local Disk

Move tempdb to SSD

People have been doing it for years

Now fully supported

AlwaysOn Availability Groups

Layman’s definition: DB mirroring for groups of databases

Components: Availability Groups Primary Replicas Multiple Secondary Replicas

Availability Group Wins

Secondary replicas Read only access Backup ops Automatic page repair Resource Utilization

Flexible Commit Modes

Flexible Failover Modes

Bells? Whistles?Ding dong. Whoot-hoot.

FileTable

File data exposed via Windows API

Simplified transition from file server

Supports files and directories

Access is non-transactional

New Data Quality Project

New Installs (when supported)

Others???

How to Upgrade

In-place Pros – no copying, same name Cons – all at once, error = disaster

recovery

Side-by-side Pros – piecemeal Cons – more work copying, configuring

Upgrade Advisor

Can analyze Data Objects T-SQL Scripts Workload Traces
