Session Code Session Title Management Studio Enhancements IntelliSense Debugging Error List Object Explorer Details Viewer Template Explorer Activity Monitor

Session Code Session Title Transact-SQL Delighters Declare and Initialize Variables Compound assignment Operators Table Value Constructor Support through the VALUES Clause

Session Code Session Title DEMO!!! Demo covering The following topics IntelliSense Debugging Error Lists Object Explorer Details Template Explorer Activity Monitor

Session Code Session Title Filtered Indexes! Have you ever wanted to create an index that filters between a static search criteria? CREATE INDEX idxName ON Schema.Table (Column) WHERE ……

Session Code Session Title Filtered Indexes! Improved query performance and plan quality if used correctly! Reduced index maintenance costs Reduced index storage costs

Session Code Session Title DEMO Filtered Indexes Demo….

Session Code Session Title New Date & Time Types SQL Server 2008 extends date/time support Larger Value Space –Current DATETIME Years –Current DATETIME Second Accuracy –New Date Types Years –New Date/Time Types - Precisions to 100 nanoseconds Variable Precision Saves Space Separate Date and Time Saves Space ANSI Compatible

Session Code Session Title Date and Time DATE Data Type Date Only to Gregorian Calendar TIME Data Type Time Only Variable Precision - 0 to 7 decimal places for seconds To 100 nanoseconds

Session Code Session Title DATETIME2 & DATETIMEOFFSET DATETIME2 Data Type to Gregorian Calendar Variable Precision - to 100 nanoseconds DATETIMEOFFSET to Gregorian Calendar Variable Precision - to 100 nanoseconds Time Zone Offset (From UTCTime) Preserved Not Time Zone Aware - No Daylight Saving Time Support

Session Code Session Title DATETIMEOFFSET SWITCHOFFSET (DATETIMEOFFSET, time_zone) Allows you to change time zones SqlDbType.DateTimeOffset

Session Code Session Title Demo!! T-SQL Date and Time DATETIMEOFFSET with.NET

Session Code Session Title Table-Value Parameters Have you wished that you could send a table into a stored procedure? Do you wish you could send all parent-child relationship data in one round-trip?

Session Code Session Title Table Types SQL Server has table variables TABLE (id int); SQL Server 2008 adds strongly typed table variables CREATE TYPE mytab AS TABLE (id int); mytab; Table-Value Parameters must use strongly typed table variables

Session Code Session Title Things to know about TVP ADO.NET 3.5 Supports Table Value Parameters You can populate TVP from the following.NET objects DataTable DbDataReader System.Collections.Generic.IList Recommended for 1000 or less records

Session Code Session Title TVP with.NET SqlParameter tvpParam = new SqlParameter(); tvpParam.ParameterName = tvpParam.Value = dtList; //DataTable in this example tvpParam.SqlDbType = SqlDbType.Structured; // This data type allows us to pass a table into DB Objects tvpParam.TypeName = "TVPComponentType"; // Name of strong typed (table type)

Session Code Session Title Demo!! Table-Value Parameters with T-SQL Table-Value Parameters with ASP.NET (C#)

Session Code Session Title MERGE!!! TRUNCATE TABLE db1.dbo.fool INSERT INTO db1.dbo.fool SELECT * FROM db2.dbo.fool

Session Code Session Title Merge Statement Multiple set operations in a single SQL statement 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

Session Code Session Title More on MERGE 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 be fired once Rows affected includes total rows affected by all clauses

Session Code Session Title MERGE Performance 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

Session Code Session Title DEMO!! Demo Merge with T-SQL!

Session Code Session Title Central Management System (CMS) & Policy Based Management Have you ever wanted to run a script against all production databases? Have you ever wanted to enforce naming conventions in SQL Programming?

Session Code Session Title CMS and PBM Central Management System Needs only 1 instance of SQL 2008 Reactive not proactive great tool for updating objects on multiple servers Policy Based Management proactive tool prevents stuff from happening great tool to enforce compliance on SQL servers

Session Code Session Title Policy Based Management Facets Conditions Policies

Session Code Session Title DEMO! Demo monitoring and enforcing naming standards with Policy Based Management

Session Code Session Title Change Data Capture Have you ever wanted to get row deltas on a table without using triggers on the source table?

Session Code Session Title Enable Change Data Capture 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

Session Code Session Title Change Data Capture data Changes stored in cdc.schema_tablename_CT _$operation column specifies change type 1 = DELETE 2 = INSERT 3 = BEFORE UPDATE 4 = AFTER UPDATE

Session Code Session Title Querying Change data cdc.fn_cdc_get_all_changes gets all changes during specific range cdc.fn_cdc_get_net_changes returns final (net change) for each row in the specific range

Session Code Session Title SSIS with CDC

Session Code Session Title DEMO! Enable and use Change Data Capture

Session Code Session Title How do you get started? Using the Transact-SQL Debugger SQL 2008 JumpStart MSDN – SQL 2008 Virtual Labs Developer Fundamentals Part 1: Uncovering T-SQL on SQL Server 2008
