Agenda Best practices Connect with SQL Server product team SQL Server Futures

Part I: Building great solutions using an increasingly feature rich product is hard!

You are looking for guidance on how to best architect your applications difficult to pick the right technologies for your application Learn how to better integrate SQL Server 2008 features into common scenarios

Turn on Data Compression RowPage Compression white paper

The general guideline is to use “ROW” compression for OLTP 2% - 5% CPU 20% Compression Compression white paper

The general guideline is to use “PAGE” compression for Data Warehousing 10% - 15% CPU 60% - 70% Compression Compression white paper Data Warehousing white paper

Backup compression Backup Compression

Use Resource Governor to prevent runaway queries Resource Governor by ExampleBackup Admin Tasks Backup OLTP Activity High High Admin Workload OLTP Workload Min Memory 10% Max Memory 20% Max CPU 20% Min Memory 10% Max Memory 20% Max CPU 20% Max CPU 90% Admin Pool Application Pool

Use MERGE for ETL SQL Server 2005SQL Server 2008 MERGE StockTable st USING TradesTable tt ON st.stock = tt.stock WHEN MATCHED THEN UPDATE SET st.quantity += tt.quantity WHEN NOT MATCHED THEN INSERT (stock, quantity) VALUES (tt.stock, tt.quantity) ; IF StockTable contains stock UPDATE quantity from TradesTable ELSE INSERT row into StockTable How to use MERGE

Use TVP to perform large data set loading White paperBatchingBatching

Use the best practices site to learn how to take advantage of new features

The site contains whitepapers More white papers at:

Part II: How can I get SQL Server to help me?

The product team seems to operate in isolation

Use some of the large variety of ways to communicate with the product team

Enhancements to the OVER clause are popular

Use Other Feedback Channels

TLC is the feedback mechanism at TechEd

Ask your questions using MSDN Forums

Use Formal Feedback Channels

Visit our customer lab

Get invited to a System Design Review

Our automated data gathering identifies feature usage and bugs

You can opt-in for anonymous & automated gathering of feature usage

Some 2008 feature usage collected: Editions and hardware configuration

SQL Server 2008: Data type usage Increasing usage Sparse Time Geometry Geography Date

SQL Server 2008: Objects per database

You can opt-in to report crashes and unexpected errors

Bugs are automatically filed by Watson and tracked by bucket and IP address

Bugs appear in Product team’s bug database automatically

You can now declare and set a variable OLD INT; = 5; NEW INT = 5;

You now have to type fewer characters when adding a variable to itself OLD UPDATE Tbl SET c1 = c1 + 5 WHERE c1 < 10; NEW UPDATE Tbl SET c1 += 5 WHERE c1 < 10; This also works for *, -, /

We made inserting multiple rows into a table much easier OLD INSERT (custid,name) VALUES (1, 'cust 1'); INSERT (custid,name) VALUES (2, 'cust 2'); INSERT (custid,name) VALUES (3, 'cust 3'); INSERT (custid,name) VALUES (4, 'cust 4'); INSERT (custid,name) VALUES (5, 'cust 5'); NEW INSERT (custid, name) VALUES (1, 'cust 1'), (2, 'cust 2'), (3, 'cust 3'), (4, 'cust 4'), (5, 'cust 5');

We made using a constant table super easy as well! OLDNEW SELECT * FROM ( VALUES (1, 'cust 1'), (2, 'cust 2'), (3, 'cust 3'), (4, 'cust 4'), (5, 'cust 5') ) MyCustomers(custid, name); TABLE (custid INT, name VARCHAR(20)) INSERT (custid,name) VALUES (1, 'cust 1'); INSERT (custid,name) VALUES (2, 'cust 2'); INSERT (custid,name) VALUES (3, 'cust 3'); INSERT (custid,name) VALUES (4, 'cust 4'); INSERT (custid,name) VALUES (5, 'cust 5'); SELECT *

Part III: Give you a glimpse into what is coming up in SQL Server 2008 R2

2008 R2 will have support for 256 logical processors

2008 R2 will support Unicode compression CompressCompress

Themes That Remain Unchanged From Release to Release Enterprise data platform Dynamic development Beyond Relational Pervasive Insight
