SQL Server 2008 R2 for Developers@LynnLangit & @LlewellynFalco

SESSION CODE: DAT312

SQL Server 2008 R2 – So Many Features…

• Lifecycle Management– DACPACs (Data Tier Applications)

• T-SQL enhancements– Geospatial data types– XML data enhancements– Filestreams (BLOBS)– Sparse Columns– Filtered indices and full-text search

• Programmability– Entity Framework

For Developers & DBAs

Data Tier Applications (DAC)

• A single container for management for scripts++• Simplifies Development & Deployment• Has Version number for each container• Includes Policies (deployment prerequisites)

• From SSMS, VS2010 and more• For SQL Server, SQL Azure

Full-text

Sparse Columns

T-SQL Enhancements• MERGE

- Less scans through table & more query flexibility

• GROUPING SETS - Less scans through table & more query flexibility

• Table-valued strongly-typed parameters- Less round trips to database

Better T-SQL

More T-SQL Enhancements• Sparse Column enhancements• XML enhancements• Geospatial enhancements• Filestream enhancements• Full-text enhancements

Better Data types

Entity Framework• What is EF?

– Object/Relational Mapping (ORM) framework

• How to use EF– query using LINQ– retrieve & manipulate data as strongly typed objects– LINQ to Entities provides IntelliSense

• Why use EF?– work with relational data as domain-specific objects – eliminates the need for most of the data access plumbing code that you

previously wrote

New in SP1•New or Improved Dynamic Management Views

--sys.dm_exec_query_stats --additional columns (long-running queries)--new DMVs and XEvents on select performance counters are introduced to monitor OS configurations/resource conditions related to the SQL Server instance

•Improved FORCESEEK index hint & New FORCESCAN query hint --syntax modified w/optional parameters allowing it to control the access method on the index even further--FORCESCAN complements the FORCESEEK hint allowing specifying ‘scan’ as the access method to the index

•Improved DACPAC - (DAC Fx) improved database upgrades: --(DAC) Framework v1.1 and DAC upgrade wizard enable the new in-place upgrade service --New in-place upgrade service will upgrade the schema for an existing database in SQL Azure and the versions of SQL Server supported by DAC

•New Disk space control for PowerPivot: --Introduces two new configuration settings --lets you determine how long cached data stays in the system
