I am not an expert but I stayed at a HolidayInn Express….

I reside in Wheeling, WV (Pittsburgh, PA)◦ Recently started Wheeling SQL Server UG

◦ Co-Host SQL Saturday #36 in Wheeling, WV

Work for Orrick Herrington & Sutcliffe LLP◦ Responsible 100+ Instances of SQL Server

◦ Responsible for PeopleSoft

Give an introduction to new features.

Give real-world cases for using new features.

This is an introduction, NOT a deep dive.

◦ Management Studio (SSMS) Enhancements

◦ T-SQL Delighters

◦ Filtered Indexes

◦ New Date and Time Data Types

◦ Table-Valued Parameters

◦ MERGE statement

◦ Policy Based Management and Central ManagementServer

◦ Change Data Capture

• IntelliSense

• Debugging

• Error List

• Object Explorer Details Viewer

• Template Explorer (SQL 2005)

• Activity Monitor

• Declare and Initialize Variables

• Compound assignment Operators

• Table Value Constructor Support through theVALUES Clause

Demo covering The following topics

• IntelliSense

• Debugging

• Error Lists

• Object Explorer Details

• Template Explorer

• Activity Monitor

Have you ever wanted to create an index thatfilters between a static search criteria?

CREATE INDEX idxName ON Schema.Table(Column) WHERE ……

• Improved query performance and planquality if used correctly!

• Reduced index maintenance costs

• Reduced index storage costs

Filtered Indexes Demo….

• SQL Server 2008 extends date/time support

• Larger Value Space– Current DATETIME - 1753-9999 Years

– Current DATETIME - 0.00333 Second Accuracy

– New Date Types - 0001-9999 Years

– New Date/Time Types - Precisions to 100nanoseconds

• Variable Precision Saves Space

• Separate Date and Time Saves Space

• ANSI Compatible

DATE Data Type◦ Date Only◦ 01-01-0001 to 31-12-9999 Gregorian Calendar

TIME Data Type◦ Time Only◦ Variable Precision - 0 to 7 decimal places for

seconds◦ To 100 nanoseconds

DATETIME2 Data Type◦ 01-01-0001 to 31-12-9999 Gregorian Calendar

◦ Variable Precision - to 100 nanoseconds

DATETIMEOFFSET◦ 01-01-0001 to 31-12-9999 Gregorian Calendar

◦ Variable Precision - to 100 nanoseconds

◦ Time Zone Offset (From UTCTime) Preserved

◦ Not Time Zone Aware - No Daylight Saving TimeSupport

• SWITCHOFFSET (DATETIMEOFFSET,time_zone)

• Allows you to change time zones (+14 to -14)

• Uses Gregorian Calendar

• SqlDbType.DateTimeOffset

T-SQL Date and Time

DATETIMEOFFSET with .NET

Have you wished that you could send a tableinto a stored procedure?

Do you wish you could send all parent-childrelationship data in one round-trip?

SQL Server has table variables◦ DECLARE @t TABLE (id int);

SQL Server 2008 adds strongly typed tablevariables◦ CREATE TYPE mytab AS TABLE (id int);

DECLARE @t mytab;

Table-Value Parameters must use stronglytyped table variables

ADO.NET 3.5 Supports Table ValueParameters

You can populate TVP from the following.NET objects◦ DataTable

◦ DbDataReader

◦ System.Collections.Generic.IList <SQLDataRecord>

Recommended for 1000 or less records

SqlParameter tvpParam = new SqlParameter();

tvpParam.ParameterName = "@TVP";

tvpParam.Value = dtList; //DataTable in this example

tvpParam.SqlDbType = SqlDbType.Structured; // This data type allowsus to pass a table into DB Objects

tvpParam.TypeName = "TVPComponentType"; // Name of strongtyped (table type)

Table-Value Parameters with T-SQL

Table-Value Parameters with ASP.NET (C#)

Once upon a time I use to build scripts likethe following:

TRUNCATE TABLE db1.dbo.fool

INSERT INTO db1.dbo.foolSELECT * FROM db2.dbo.fool

Multiple set operations in a single SQLstatement

Uses multiple sets as input◦ MERGE target USING source ON ...

Operations can be INSERT, UPDATE, DELETE Operations based on◦ WHEN MATCHED◦ WHEN [TARGET] NOT MATCHED◦ WHEN SOURCE NOT MATCHED

ANSI SQL 2006 compliant - with extensions

Multiple WHEN clauses possible◦ For MATCHED and SOURCE NOT MATCHED

◦ Only one WHEN clause for TARGET NOT MATCHED

MERGE can be used with any table source

A MERGE statement causes triggers to befired once

Rows affected includes total rows affected byall clauses

MERGE statement is transactional◦ No explicit transaction required

One Pass Through Tables◦ At most a full outer join◦ Matching rows = when matched◦ Left-outer join rows = when target not matched◦ Right-outer join rows = when source not matched

Demo Merge with T-SQL!

Have you ever wanted to run a script againstall production databases?

Have you ever wanted to enforce namingconventions in SQL Programming?

• Central Management System• Needs only 1 instance of SQL 2008

• Reactive not proactive

• great tool for running a script against multipleservers

• Policy Based Management• proactive tool prevents stuff from happening

• great tool to enforce compliance on SQL 2008+servers

• Facets

• Conditions

• Policies

Demo monitoring and enforcing namingstandards with Policy Based Management

Have you ever wanted to get row deltas on atable without using replication or triggers onthe source table?

• Must have Enterprise Edition

• Uses transaction log to pull deltas

• Enable on database (req sysadmin)• sys.sp_cdc_enable_db_change_data_capture

• creates cdc schema

• creates cdc user

• creates system tables with cdc schema

• Enable on table(s) (req db_owner)• sys.sp_cdc_enable_table

• creates sql agent jobs

• creates table cdc.schema_tablename_CT

• Changes stored incdc.schema_tablename_CT

• _$operation column specifies change type• 1 = DELETE

• 2 = INSERT

• 3 = BEFORE UPDATE

• 4 = AFTER UPDATE

• cdc.fn_cdc_get_all_changes<capture_instance>

• gets all changes during specific range

• cdc.fn_cdc_get_net_changes<capture_instance>

• returns final (net change) for each row in thespecific range

Enable and use Change Data Capture
