Return Null If A Value Is A Certain Value

You need to return NULL only if the value of your data is a certain value. How do you do this?
There are three different ways.

NULLIF
DECLARE @1 char(1)
SELECT @1 ='D'


SELECT NULLIF(@1,'D')


REPLACE
This should not really be used, I just added it here to demonstrate that you can in fact use it.

DECLARE @1 char(1)
SELECT @1 ='D'

SELECT REPLACE(@1,'D',NULL)


CASE
With case you can test for a range of values. You can test for example for values between A and D. If you reverse the logic then you also don't need to provide the ELSE part since it defaults to NULL anyway.

DECLARE @1 char(1)
SELECT @1 ='D'


SELECT CASE @1 WHEN 'D' THEN NULL ELSE @1 END

--No else needed
SELECT CASE WHEN @1 <> 'D' THEN @1 END

And this is how you test for a range.

--Null
DECLARE @1 char(1)
SELECT @1 ='D'

SELECT CASE WHEN @1 BETWEEN 'A' AND 'D' THEN NULL ELSE @1 END

--E
DECLARE @1 char(1)
SELECT @1 ='E'

SELECT CASE WHEN @1 BETWEEN 'A' AND 'D' THEN NULL ELSE @1 END

Microsoft Commits to November Release Date for Visual Studio 2008 and the .NET Framework 3.5

Today, during the keynote address at Microsoft TechEd Developers 2007, S. “Soma” Somasegar, corporate vice president of the Developer Division at Microsoft Corp., announced that Microsoft will release Visual Studio 2008 and the .NET Framework 3.5 by the end of November 2007. Visual Studio 2008 and the .NET Framework 3.5 enable developers at all levels to rapidly create connected applications that offer compelling user experiences for Windows Vista, Windows Server 2008, the 2007 Microsoft Office system, mobile devices and the Web. Soma also unveiled plans to open new opportunities for Visual Studio partners, as well as to deliver new tools and resources for developers, including a first Community Technology Preview (CTP) of the Microsoft Sync Framework and new capabilities for Popfly Explorer.

“The highly social and visual nature of the Web has fundamentally changed what users expect from all applications they interact with, regardless of whether it’s on a customer-facing Web site or Windows rich client application, or a desktop business application built using Microsoft Office,” said Somasegar. “Traditionally, organizations have been hard pressed to deliver the richer, more connected applications and services they need to boost productivity, drive revenue and stay ahead of the competition. With Visual Studio 2008 and the .NET Framework 3.5, it is easy for developers to use the skills they already have to build compelling applications that take advantage of the latest platforms.”

FWBS Ltd., Xerox Corp., Dell Inc. and K2 are just a few of the early adopter customers that are already experiencing the benefits of these releases. FWBS used Visual Studio, the .NET Framework and the Microsoft Office system to build an Office Business Application (OBA) for the law field. The application enables users to work within Microsoft Office — the tools they use every day — while also dramatically improving productivity and helping users respond quickly to changing business needs.

Xerox has also had early success developing applications with the new tools. “We’ve already seen significant advantages from using Visual Studio Team System 2008 and .NET Framework 3.5. With the first application we built, we easily saved 50 percent of the time and money it would have taken to create the same application with other tools,” said Eugene Shustef, feature design lead, Global Technology, Xerox. “That’s more than a savings to IT — it delivers a huge time-to-market advantage because it put the tool into the hands of our analysts six months sooner than they would have had it otherwise.”

Creating New Opportunities for Partners

Microsoft also announced plans to make additional investments in the Visual Studio partner ecosystem. In response to partner feedback and in order to provide better support for interoperability with other developer tools and cross-platform scenarios, Microsoft is today announcing plans to change licensing terms, no longer limiting partners to building solutions on top of Visual Studio for Windows and other Microsoft platforms only. This licensing change will be effective for the release of Visual Studio 2008 and the Visual Studio 2008 SDK.

“Integrating dynaTrace’s cross-platform application performance management and diagnostics product with Visual Studio has opened up additional commercial opportunities for our business and delivered a compelling solution for our customers. .NET and Visual Studio is a strategic platform for our business, and Microsoft’s additional investments in the partner ecosystem make it even more compelling,” said Klaus Fellner, senior director of product marketing at dynaTrace. “We’re looking forward to taking advantage of the new technology available with the launch of Visual Studio 2008 and the partner benefits available through the Visual Studio Industry Partner (VSIP) program.”

In addition, Microsoft announced plans to create a shared source licensing program for Premier-level partners in the VSIP program. The program will provide these partners with the ability to view Visual Studio IDE source code for debugging purposes, and simplify the process of integrating their products with Visual Studio 2008.

Tools for Today and Tomorrow

Microsoft also announced a number of additional resources for developers of all skill sets, enabling them to make the most out of their Microsoft tools investments to build great applications on the latest platforms:

• The first CTP of the Microsoft Sync Framework demonstrates Microsoft’s ongoing investments in synchronization and builds on the synchronization functionality available in Visual Studio 2008. With Visual Studio 2008, developers can rapidly take advantage of offline synchronization capabilities to sync-enable applications and services easily with rich designer support. The Microsoft Sync Framework extends the support featured in Visual Studio 2008 to also include offline and peer-to-peer collaboration using any protocol for any data type, and any data store. This is part of Microsoft’s long-term commitment to providing synchronization for partners and independent software vendors that can embed the Sync Framework into their applications easily to create rich sync-enabled ecosystems that allow any type of data to follow their customers wherever they go.



• A new release of Popfly Explorer will add new Web tools that provide Web developers and Popfly users an easy way to add Silverlight gadgets built in Popfly to their Web pages, as well as publish HTML Web pages directly to Popfly.


These latest releases are part of the broader Microsoft Application Platform, a portfolio of technology capabilities and core products that help organizations develop, deploy and manage applications and IT infrastructure. They also mark another major milestone leading up to the global launch of Windows Server 2008, Visual Studio 2008 and SQL Server 2008 on Feb. 27, 2008, in Los Angeles.

Product Information and Availability

Visual Studio 2008 and the .NET Framework 3.5 will be available by the end of November 2007. The .NET Framework 3.5 will also be available to end users via a free, optional download from Microsoft Update. A CTP of Microsoft Sync Framework is available today at http://msdn.microsoft.com/sync. Popfly Explorer is a hosted development environment available today at http://www.popfly.com. More information about all of these releases is available at http://www.msdn.microsoft.com/vstudio.

Sort Values Ascending But NULLS Last

This is a frequent request in newsgroups and fora. People want to sort the column in ascending order but don't want the NULLS at the beginning.
Oracle has this syntax: ORDER BY ColumnName NULLS LAST;
SQL Server does not have this. But there are 2 ways to do this. The first one is by using case and the second one by using COALESCE and the maximum value for the data type in the order by clause.

The 2 approaches with a datetime data type

DECLARE @Temp table(Col datetime)
INSERT INTO @Temp VALUES(getdate())
INSERT INTO @Temp VALUES('2007-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2006-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2005-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2006-10-19 09:54:03.730')
INSERT INTO @Temp VALUES('2004-10-19 09:54:03.730')
INSERT INTO @Temp VALUES(NULL)
INSERT INTO @Temp VALUES(NULL)

SELECT *
FROM @Temp
ORDER BY COALESCE(Col,'9999-12-31 23:59:59.997')

SELECT *
FROM @Temp
ORDER BY CASE WHEN Col Is NULL Then 1 Else 0 End, Col

The 2 approaches with an integer data type

DECLARE @Temp table(Col int)
INSERT INTO @Temp VALUES(1)
INSERT INTO @Temp VALUES(555)
INSERT INTO @Temp VALUES(444)
INSERT INTO @Temp VALUES(333)
INSERT INTO @Temp VALUES(5656565)
INSERT INTO @Temp VALUES(3)
INSERT INTO @Temp VALUES(NULL)
INSERT INTO @Temp VALUES(NULL)

SELECT *
FROM @Temp
ORDER BY COALESCE(Col,'2147483647')

ORDER BY CASE WHEN Col Is NULL Then 1 Else 0 End, Col

Interview With Kalen Delaney About Inside Microsoft SQL Server 2005 Query Tuning and Optimization

I am a big fan of Inside Microsoft SQL Server 2005 The Storage Engine so when I saw that yet another book got published in this series I just had to check it out. Inside Microsoft SQL Server 2005: Query Tuning and Optimization is very well written gets to the point and give you the answers that you need. I decided to contact Kalen to see if she would be willing to do an interview, by now you know that the answer is yes of course ;-)


The question-and-answer session with Kalen that follows was conducted via email.

What is the audience for this book, is it the enterprise user or can a small department benefit from the tips in this book?
Because this book deals with query tuning, anyone who writes SQL queries for SQL Server can benefit. Very little in the book is geared towards system tuning, so the size of the machine doesn’t really matter. Now of course, if you have a very small system with very small tables, you won’t get as much benefit out of tuning your queries. However, if you have any tables of more than a few thousand rows, and you do any joins, you will need to tune your queries. In addition, the issues of blocking and concurrency control can impact any system, no matter how small.

What new technologies in SQL Server 2005 do you think are the most beneficial for performance?
For very large databases, the best new technology is partitioning. For any size system, if you have had serious performance problems due to blocking, you might find a big performance benefit by using one of the snapshot-based isolation levels, but you really need to understand the resource costs that come along with the improved performance. For your individual queries, I think the new optimizer hints and query level recompiles can make a big difference. For indexes, the ability to add included columns to nonclustered indexes can give some of your hard-to-tune queries a major performance boost.

What will a person who reads this book gain in terms of understanding how to performance tune a server?
The focus of this book is not so much on tuning the server, but on tuning queries. There is more in Inside SQL Server 2005: The Storage Engine on server issues such as memory and processor management. The biggest server wide issues are covered in Chapter 5, when I talk about managing the plan cache, and how and when query plans are reused.

Is the book geared towards a beginner/intermediate level user or do you have to be an advanced user to really utilize the information in this book?
The book is not geared towards beginners, but everyone should be able to get something out of it. It’s primarily geared to SQL Server developers and DBA’s who have been working with SQL Server for a while, and have encountered performance problems that they are trying to find solutions for.

With all the changes in SQL Server 2005, how critical has the tempdb become in regards to performance?
Tempdb has always been important. In SQL Server 2005, if you are using one of the snapshot-based isolation levels, you are going to have to be more aware of the demands placed on tempdb, both in the sizing requirements and the additional I/O resources needed. Fortunately, SQL Server 2005 provides tools to monitor tempdb, including a dozen new performance monitor counters, and a dynamic management view, sys.dm_db_file_space_usage, that keeps track of how much space in tempdb is being used for each of the different kind of object stored in tempdb.

I understand that this is the first time you wrote with a team of other writers; can you tell us something about that experience?
I initially thought that not having to write the whole volume by myself meant that I could get it done sooner, but that was not the case. Everyone had their own schedule and their own way of writing. The personal aspect of working with the other authors was great. I deeply respect all of the others and it was an honor to be working so closely with them. I had some concerns about the depth of coverage and I wondered whether all the chapters would end up being as deep as I hoped for, but that turned out not to be a major problem. The only real issues were agreeing on a common terminology and coding style, and even that wasn’t that big of an issue, because I got to do a final editing pass on everyone’s chapters.

What SQL Server books are on your bookshelf?
All of the Inside SQL Server books are there, of course, and all of Ken Henderson’s books. Bob Beauchemin’s book is in my car, to read while I am waiting for the ferryboat, and while on the ferry. I also have technical books that aren’t SQL Server specific, such as Jim Gray’s Transaction Processing, Russinovich’s and Solomon’s Windows Internals, Chris Date’s Introduction to Database Systems and Mike Stonebraker’s Readings in Database Systems.

Why do you write technical books?
I love working with SQL Server and trying to find out all I can about it. When I found that I could explain difficult concepts in a training environment, I thought I could do the same thing in a written format, and reach more people that way. I have always loved explaining things, ever since I was a teaching assistant for High School Math.

Will you be updating your books for SQL Server 2008?
I have just started meeting with my editors at Microsoft Press about SQL Server 2008, and it looks like a revision is in the plans. We’re really looking at it as just a revision, with the same structures as the current books, with straightforward changes and the inclusion of new features.

Name three things that are new in SQL Server 2005 that you find are the most valuable?
Dynamic Management Views, Dynamic Management Views, and Dynamic Management Views!
Oh, you wanted three different things? ;-) How about XML query plans and optimization hints. (I’m also very fond of many of the new TSQL constructs, but I was only talking about things that I cover in my new book.)

Name three things which are coming in SQL Server 2008 that you are most excited about?
You’ll have to ask me this next time. I have actually been avoiding SQL Server 2008 while I was getting my Query Tuning and Optimization book finished, because I didn’t want to get distracted.

Can you list any third party tools that you find useful to have as a SQL Server developer/admin?
I’ve tried a few other products, but usefully I find that it is much easier to just stick with the Microsoft line and use the tools provided with the product.

Name some of your favorite non-technical books.
Oh, I love to read. It would be impossible to list my favorite books, but I can tell you my favorite authors, most of whom write science fiction: Lois McMaster Bujold, Ursula LeGuin, Sheri Tepper, Orson Scott Card, Octavia Butler, Elizabeth Moon. I also love to read historical fiction like Leon Uris.

How to find out the recovery model for all databases on SQL Server 2000, 2005 and 2008

How do you find out the recovery model for all the databases on your SQL Server box?
On a SQL Server 2005/2008 box you can use the sys.databases view, the sys.databases view returns a column named recovery_model_desc.
On a SQL server 2000 box you will have to use the DATABASEPROPERTYEX function. The 2000 version will also work on 2000 and 2008 (I tested this with the July CTP)


--2005/2008 version
SELECT [name],
recovery_model_desc
FROM sys.databases


--2000/2005/2008 version
SELECT [name],
DATABASEPROPERTYEX([name],'Recovery') AS recovery_model_desc
FROM master..sysdatabases

Screencast: SQL Server Analysis Services what's in it for me?

SQL Server Analysis Services is a very powerful tool, which was introduced with SQL Server 2000. In SQL Server 2005 it is far more powerful, but still underappreciated by a lot of developers. This is a quick and dirty attempt to convey the value of Analysis Services cubes in under ten minutes. Related Resources:

SQL Teaser PASS Special: Table Size

What will be the outcome of this script?
First we create a table with a total of 6000 bytes
Next we increase col2 from 1000 to 2000 bytes, this will give us a total of 7000 bytes
Finally we add col3 which has 1000 bytes, this will give us a total of 8000 bytes

First run these two statements
--Total size = 6000
CREATE TABLE TestSize (Col1 char(5000),col2 char(1000))
GO

--total size = 7000
ALTER TABLE TestSize
ALTER COLUMN col2 char(2000)
GO

Now what do you think will happen when you run this?

--total size should be 8000 bytes (5000 + 2000 + 1000)
ALTER TABLE TestSize
ADD Col3 char(1000)
GO

Now for bonus points. What book have I been reading.

SQL Injection Cheat Sheet

What is SQL Injection? From wikipedia: SQL injection is a technique that exploits a security vulnerability occurring in the database layer of an application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed

Here is a nice SQL injection cheat sheet. Currently only for MySQL and Microsoft SQL Server, some ORACLE and some PostgreSQL

SQL Gotcha: Do you know what data type is used when running ad-hoc queries?

This is for SQL Server 2000 only, SQL Server 2005 is a lot smarter which is another reason to upgrade.
When running the following query you probably already know that 2 is converted to an int datatype


SELECT *
FROM Table
WHERE ID =2

What about the value 2222222222? Do you think since it can't fit into an int that it will be a bigint? Let's test that out.
First create this table.

CREATE TABLE TestAdHoc (id bigint primary key)

INSERT INTO TestAdHoc
SELECT 1 UNION
SELECT 2433253453453466666 UNION
SELECT 2 UNION
SELECT 3 UNION
SELECT 4 UNION
SELECT 5 UNION
SELECT 6


Now let's run these 2 queries which return the same data

SELECT *
FROM TestAdHoc
WHERE ID =2433253453453466666



SELECT *
FROM TestAdHoc
WHERE ID =CONVERT(bigint,2433253453453466666)

Now run the following SET statement and run the 2 queries again

SET SHOWPLAN_TEXT ON

SELECT *
FROM TestAdHoc
WHERE ID =2433253453453466666


SELECT *
FROM TestAdHoc
WHERE ID =CONVERT(bigint,2433253453453466666)

And what do we see?

First Query
--Nested Loops(Inner Join, OUTER REFERENCES:([Expr1002], [Expr1003], [Expr1004]))
--Compute Scalar(DEFINE:([Expr1002]=Convert([@1])-1,
[Expr1003]=Convert([@1])+1, [Expr1004]=If (Convert([@1])-1=NULL)
then 0 else 6If (Convert([@1])+1=NULL) then 0 else 10))
--Constant Scan
--Clustered Index Seek(OBJECT:([Blog].[dbo].[TestAdHoc].[PK__TestAdHoc__2818EA29]),
SEEK:([TestAdHoc].[id] > [Expr1002] AND [TestAdHoc].[id] < [Expr1003]), WHERE:(Convert([TestAdHoc].[id])=[@1]) ORDERED FORWARD)

Second Query
--Clustered Index Seek(OBJECT:([Blog].[dbo].[TestAdHoc].[PK__TestAdHoc__2818EA29]),
SEEK:([TestAdHoc].[id]=2433253453453466666) ORDERED FORWARD)


The first query has a much different execution plan than the second query. The first execution plan has a lot more than the second execution plan and will be a little slower.

So how do you know what dataype the value is converted to? Here is a simple SQL query which I first saw on Louis Davidson's blog. Just run this query.

SELECT CAST(SQL_VARIANT_PROPERTY(2433253453453466666,'BaseType') AS varchar(20)) + '(' +
CAST(SQL_VARIANT_PROPERTY(2433253453453466666,'Precision') AS varchar(10)) + ',' +
CAST(SQL_VARIANT_PROPERTY(2433253453453466666,'Scale') AS varchar(10)) + ')'

So the output is this numeric(19,0). So instead of a bigint SQL Server converts the value to a numeric data type.
Here is another query which demonstrates the different datatypes used.


SELECT CAST(SQL_VARIANT_PROPERTY(2,'BaseType') AS varchar(20))
UNION ALL
SELECT CAST(SQL_VARIANT_PROPERTY(222222222,'BaseType') AS varchar(20))
UNION ALL
SELECT CAST(SQL_VARIANT_PROPERTY(2222222222,'BaseType') AS varchar(20))


So when running ad-hoc queries it is always a good practice to use parameters or inline convert statements.
