How to Backup Your Blogger Blog

If you have a blog hosted on Blog*Spot (Blogger) and you've upgraded to the new version, there's an easy way to backup your blog. The Google Operating System blog shows you just the way to do this. The link to the article is below

Use A Combination OF NULLIF and COALESCE TO Display A Custom Value

Let's you inherit a table with a column that can contain blanks, empty strings or NULL values. I am saying inherit because surely you would have a constraint on the column that wouldn't allow those values to begin with right? For all the values that are '',' ' or NULL you want to display 'N/A'.
What is the best way to do this? You can Use CASE and test for the values or you can use COALESCE with NULLIF which is much shorter. A lot of people don't know that you can stack these functions so that it makes your life so much easier.
Let's get started

CREATE TABLE Blah (SomeCol VARCHAR(33))

INSERT Blah VALUES(NULL)
INSERT Blah VALUES('')
INSERT Blah VALUES(' ')
INSERT Blah VALUES('A')
INSERT Blah VALUES('B B')

--Using COALESCE and NULLIF
SELECT COALESCE(NULLIF(RTRIM(SomeCol),' '),'N/A')
FROM Blah


--Using CASE
SELECT CASE WHEN RTRIM(SomeCol) = '' THEN 'N/A'
WHEN RTRIM(SomeCol) IS NULL THEN 'N/A'
ELSE SomeCol END SomeCol
FROM Blah


Output for both queries
-----------------------
N/A
N/A
N/A
A
B B

More Than 10 Tips To Help Your Virtual PC Performance.

John Carpenter’s The Thing

I brought in John Carpenter’s The Thing to work only to discover that 80% of my co-workers never heard of this movie. This movie is probably one of the best in its genre. If you like Alien(s) then you will love this movie. The story is about a bunch of researchers on Antarctica, they discover a spaceship and take a dog in (bad idea) I won’t spoil the story but let’s just say that a lot of people die. I watched this movie at least 10 times since its release in 1982. even nowadays the special effects are still amazing.

IMDB lists this movie in the top 250 movies of all time with a rating of 8.0 and 29,153 votes. If you have problems picking out a movie at blockbuster with your significant other then consider this a favor because I know what it feels like spending 30 minutes in Blockbuster trying to agree on a movie. I even went home a couple of times without a movie because my wife and I couldn’t agree on a movie. So what are you waiting for it is Saturday afternoon (well it is in Princeton, NJ anyway)? Go to the movie rental store and watch this movie. Let me know what you thought of it after you watch it

If you are in doubt then just check out the comments on IMDB http://www.imdb.com/title/tt0084787/usercomments

And here is the trailer

Give Me One Good Reason Why You Would Store Documents In The Database?

Why would you ever store PDF, Doc or Excel files in the database? What is the point? I don't see any advantages only disadvantages
Let's say you have 8 webservers and 1 big SQL monster. If you store these documents in the DB and you get hit by these 8 webservers for documents all the time your DB is going to slow down. A much better way is to have the files on the webservers itself, sending 9MB pdf files over the network is just wrong.
Also if you store all these files in the DB your backups will take much longer.
Updating BLOBs is another pain in the neck; UPDATETEXT and WRITETEXT are not my favorite SQL commands.

So here is the question:
Would you store images/documents/spreadsheets in the Database and why?

How To Restart A Remote Computer

Sometimes you have to login to your work PC from home over the VPN and after a while for some reason or another you want to restart your PC. How can you do that? You can't use the start menu because only the log off button is displayed
Well one way is to open a command window and executing shutdown -r
That will restart your computer

Here is the basic usage of the shutdown command

Usage: shutdown [-i -l -s -r -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]

No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c "comment" Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without warning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536)

Need Help With Picking Out An ASP.NET 2.0 Book

I decided to get back into some web development again, the last time I did this was in October 2001. I have developed in ASP, JSP and ColdFusion. Since I know some C# and have been using that on and off for the last 2 years with windows forms I decided to use ASP.NET 2.0. Another factor is that it is also a corporate standard at work.
So for someone like me which book would you recommend? Or maybe you have read an ASP.NET book that is just awesome either way let me know.

Don't worry I will never spend less than 51% of my time with SQL ;-)

Are You ready For Daylight Saving Time Changes In 2007

In August of 2005 the United States Congress passed the Energy Policy Act, which changes the dates of both the start and end of daylight saving time (DST). When this law goes into effect in 2007, DST will start three weeks earlier (2:00 A.M. on the second Sunday in March) and will end one week later (2:00 A.M. on the first Sunday in November) than what had traditionally occurred.

Microsoft SQL Server Database Publishing Wizard 1.0,SharePoint Server 2007 SDK And Windows SharePoint Services v3 SDK Available For Download

Microsoft SQL Server Database Publishing Wizard 1.0
SQL Server Database Publishing Wizard enables the deployment of SQL Server databases into a hosted environment on either a SQL Server 2000 or 2005 server. It generates a single SQL script file which can be used to recreate a database (both schema and data) in a shared hosting environment where the only connectivity to a server is through a web-based control panel with a script execution window. If supported by the hosting service provider, the Database Publishing Wizard can also directly upload databases to servers located at the shared hosting provider.

Optionally, SQL Server Database Publishing Wizard can integrate directly into Visual Studio 2005 and/or Visual Web Developer 2005 allowing easy publishing of databases from within the development environment.



SharePoint Server 2007 SDK
The Microsoft Office SharePoint Server 2007 Software Development Kit (SDK) contains conceptual overviews, programming tasks, code samples, references, and an Enterprise Content Management (ECM) starter kit to guide you in developing solutions based on Microsoft Office SharePoint Server 2007.

Windows SharePoint Services v3 SDK
The Windows SharePoint Services 3.0 software development kit (SDK) contains conceptual overviews, programming tasks, samples, and references to guide you in developing solutions based on Microsoft Windows SharePoint Services 3.0.

Check If Auto Update Statistics Is Enabled With DATABASEPROPERTY

How do you check if auto update statistics is enabled on your database? It is pretty easy to check that, you can use the DATABASEPROPERTY function
Run the following line of code

SELECT DATABASEPROPERTY('pubs','IsAutoUpdateStatistics') AS IsAutoUpdateStatistics

If 1 is returned(true) it is enabled, if 0 is returned(false) then it is not enabled

Now to save me (and you) time I have pasted a code block below with all the properties, just change the database name from pubs to your database name and run the code


DECLARE @v VARCHAR(55)
SELECT @v = 'pubs'

SELECT
DATABASEPROPERTY(@v,'IsAnsiNullDefault') AS IsAnsiNullDefault,
DATABASEPROPERTY(@v,'IsAnsiNullsEnabled') AS IsAnsiNullsEnabled,
DATABASEPROPERTY(@v,'IsAnsiWarningsEnabled') AS IsAnsiWarningsEnabled,
DATABASEPROPERTY(@v,'IsAutoClose') AS IsAutoClose,
DATABASEPROPERTY(@v,'IsAutoCreateStatistics') AS IsAutoCreateStatistics,
DATABASEPROPERTY(@v,'IsAutoShrink') AS IsAutoShrink,
DATABASEPROPERTY(@v,'IsAutoUpdateStatistics') AS IsAutoUpdateStatistics,
DATABASEPROPERTY(@v,'IsBulkCopy') AS IsBulkCopy,

DATABASEPROPERTY(@v,'IsAutoClose') AS IsAutoClose,
DATABASEPROPERTY(@v,'IsInStandBy') AS IsInStandBy,
DATABASEPROPERTY(@v,'IsLocalCursorsDefault') AS IsLocalCursorsDefault,
DATABASEPROPERTY(@v,'IsNotRecovered') AS IsNotRecovered,
DATABASEPROPERTY(@v,'IsNullConcat') AS IsNullConcat,
DATABASEPROPERTY(@v,'IsOffline') AS IsOffline,
DATABASEPROPERTY(@v,'IsQuotedIdentifiersEnabled') AS IsQuotedIdentifiersEnabled,
DATABASEPROPERTY(@v,'IsReadOnly') AS IsReadOnly,
DATABASEPROPERTY(@v,'IsRecursiveTriggersEnabled') AS IsRecursiveTriggersEnabled,
DATABASEPROPERTY(@v,'IsShutDown') AS IsShutDown,
DATABASEPROPERTY(@v,'IsSingleUser') AS IsSingleUser,

SQL Server Doesn't Like Cheaters

I emailed a joke(see below) to some friends and one of them replied: "So what you're saying is that I should take a mistress?"

So that got me thinking, what would SQL say about this? Is mistress equal to mistrust. Well according to SQL server it is, run this in Query Analyzer

SELECT SOUNDEX('mistress'),SOUNDEX('mistrust'),DIFFERENCE('mistress','mistrust')

And here is the joke:

Two Ladies talking in heaven

1st woman: Hi! My name is Wanda.

2nd woman: Hi! I'm Sylvia. How'd you die?

1st woman: I Froze to Death.

2nd woman: How Horrible!

1st woman: It wasn't so bad. After I quit shaking from the cold, I
began to get warm & sleepy, and finally died a peaceful death. What
about you?

2nd woman: I died of a massive heart attack. I suspected that my
husband was cheating, so I came home early to catch him in the act.
But instead, I found him all by himself in the den watching TV.

1st woman: So, what happened?

2nd woman: I was so sure there was another woman there somewhere that I started running all over the house looking. I ran up into the attic and searched, and down into the basement. Then I went through every closet and checked under all the beds. I kept this up until I had looked everywhere,and finally I became so exhausted that I just keeled over with a heart attack and died.

1st woman: Too bad you didn't look in the freezer---we'd both
still be alive.


So what is the point of this all? Well it gives you a reason to run those barely used functions like SOUNDEX and DIFFERENCE ;>

A Witchbrew Of SQL Server News And Interesting Links

Since I have nothing interesting or fascinating to say I decided to put some links up to some posts of people who do have something interesting to say.
We will start with Hugo Kornelis who has two posts about why clustered index ordering is not guaranteed in SQL Server. The first article can be found here: http://sqlblog.com/blogs/hugo_kornelis/archive/2006/12/31/Beatles-vs-Stones.aspx
And the second article that explains the behaviour can be found here: Beatles vs Stones Explanation

Developer.com has announced their Database Tool or Add-in winner and the winner is......SQL Server 2005. You can read the whole article here http://www.developer.com/db/article.php/10920_3653956_1

Euan Garden has a post telling us that SQL Server Compact Edition launches (finally)

Tim O'Reilly posted his latest State of the Computer Book Market article and SQL server is still going strong. You can fnd that article here: State of the Computer Book Market, Q4 06, Part 1, Overall Market Trend

And we will end with Internet Maverick Marc Cuban who wrote an interesting article titled Why I Don't Wear a Suit and Can't Figure Out Why Anyone Does !
I don't wear a suit either, I actually wear jeans and sneakers most of the time. When i used to work in Silicon Alley (Broadway and 21st street in New York City) I actually came to work in shorts in the summer but then again what do you expect when you have 2 lizards and a cat roaming around the office?

sp_refreshview

Did you know that when you create a view and then later change the table the view is not updated?
Don't believe me? Run the following block of code

CREATE TABLE TestTable (id INT,SomeCol VARCHAR(666))
GO

INSERT TestTable VALUES(1,'ABC')
GO

SELECT * FROM TestTable
GO

CREATE VIEW TestView
AS
SELECT * FROM TestTable
GO

SELECT * FROM TestView
GO


ALTER TABLE TestTable
ADD Col2 DATETIME DEFAULT CURRENT_TIMESTAMP
GO

INSERT TestTable(id,SomeCol) VALUES(2,'XYZ')
GO

SELECT * FROM TestTable
GO

SELECT * FROM TestView
GO

See what happened? The TestView does not include the Col2 column. So what can you do? There are at least two things that you can do. You can recreate the view with a create or alter statement or you can use sp_refreshview, run the code below to see how that works

sp_refreshview TestView
GO

--All good now
SELECT * FROM TestView
GO


--Clean up this mess--
DROP VIEW TestView
GO


DROP TABLE TestTable
GO


And yes I know 'real' SQL programmers never use SELECT * and 'real' SQL programmers name their defaults ;-)

Visual Studio Code Name "Orcas" - January Community Technology Preview (CTP) Released

Visual Studio Code Name "Orcas" - January Community Technology Preview (CTP) has been released.
This CTP is available as a Virtual PC image or as a self-extracting install. If you wish to use the Virtual PC image you will need Virtual PC or Virtual Server to run this image. If you wish to use the self extracting install, we advise that you do not install this on a production machine. Depending on your hardware the download files make take between 30-60 minutes to decompress.



The highlights of this CTP include:

• Extended, more powerful data APIs with the ADO.NET Entity Framework and LINQ to ADO.NET
  
  • With the ADO.NET Entity Framework developers will be able to model the view of the data that is appropriate for each one of the applications they are building, independently of the structure of the data in the underlying database. The use of the Entity Data Model (EDM) enables developers to design models that follow the concepts built into the application, instead of having to map them to constructs available in relational stores. Once the model is in place, the powerful ADO.NET Entity Framework API is used to access and manipulate the data as .NET classes or as rows and columns, whatever is appropriate for each application.
    
  
  
  • ADO.NET is fully integrated with LINQ and offers many options for using LINQ in various scenarios: LINQ to SQL provides direct access to database tables from the programming environment, LINQ to Entities enables developers to use LINQ over EDM models, and LINQ to DataSet allows the full expressivity of LINQ to be used over DataSets.
    
  
  

• C# 3.0 Language Support: This CTP implements all of the C#3.0 language features from the May LINQ CTP including:
  
  • Query Expressions
  
  
  • Object and Collection Initializers
  
  
  • Extension Methods
  
  
  • Local Variable Type Inference and Anonymous Types
  
  
  • Lambdas bound to Delegates and Expression trees
  
  

• VB 9.0 Language Support: This CTP implements all of the VB 9.0 language features from the May LINQ CTP including:
  
  • Query Expressions
  
  
  • Object Initializers
  
  
  • Extension Methods
  
  
  • Local Variable Type Inference
  
  
  • Anonymous Types
  
  

• LINQ to Objects API
  
  • The LINQ to Objects API supports queries over any .NET collection, such as arrays and Generic Lists. This API is defined in the System.Linq namespaces inside System.Core.dll. Click here for more details about LINQ.
    
  
  

• ClickOnce improvements
  
  • This CTP delivers ClickOnce improvements for the deployment of Windows Presentation Foundation applications, alternative browser support and ISV rebranding.
    
  
  

• Managed classes for Elliptic Curve Diffie Hellman and Elliptic Curve Digital Signature Algorithm cryptographic functionality
  
  • With the addition of these classes, cryptographic developers now have managed classes for Elliptic Curve Diffie Hellman secret agreement and Elliptic Curve Digital Signature Algorithm signing. These classes are built on the new CNG cryptographic libraries in Windows Vista, but still follow the familiar patterns of the cryptographic classes in .NET Framework 2.0.
    
  
  

• Runtime and design-time support for Office 2007 (including Outlook 2007)
  
  • Customers can build managed code add-ins with a consistent development experience, regardless of which version of Office they target, which Office application(s) they target, and which programming language they choose. Managed code add-ins enable developers to use strongly-typed class members, with the help of modern development tools, including intellisense and auto-complete. Additionally add-ins can potentially run in multiple versions of Office, enabled by abstracting version-specific code and supported by a version-resilient infrastructure.
    
  
  

• Support for advanced lifetime management of add-ins and their AppDomains
  
  • We’ve added the helper classes that manage the lifetime of add-ins, the objects passed between the host and add-ins, and even of the AppDomains the add-ins live in. By using the ContractBase and LifetimeToken handle, pipeline developer can let the hosts and add-ins act as if everything, including the AppDomain the add-in was activated in, was controlled by the garbage collector even though .Net Remoting would normally make that impossible.
    
  
  

• Client service support for Login/Logout, Role management and Profiles
  
  • ASP.NET 2.0 shipped with new application services for authentication, authorization and personalization. Most of these services are not tied to ASP.NET and can work in non-web applications. This CTP enables the use of these services in smart client applications for Logon/Logoff, Role management and profiles.
    
  
  

• A trace listener that logs event to ETW, event tracing for Windows in Vista
  
  • Event tracing for windows is greatly improved in Vista and the most performant loggings facility available in Windows. The System.Diagnostics.EventProviderTraceListener allows managed tracing to provide events to the Vista’s ETW infrastructure. This is a highly performant, thread-safe listener.
    
  
  

• Jscript Intellisense support
  
  • Jscript code formatting and Intellisense support provide developers with a richer editing experience. These improvements enable the IDE to provide statement completion, color syntax highlighting and in-place documentation to Jscript and associated script models such as ASP.NET AJAX.
    
  
  

• A new numeric type that provides support for very large numbers (Beyond the range of In64)
  
  • All existing numeric types in the Framework have a limited range. This is the first type that supports arbitrary range and will extend to accommodate any large number as needed. This type lives in the new System.Numeric namespace where all new numeric and arithmetic features are going to reside. It supports all the basic arithmetic operations including things like Pow, DivRem and GreatestCommonDivisor. It implements the following interfaces: IFormattable, IComparable, IComparable<BigInteger> and IEquatable<BigInteger>. It is serliazable and immutable. It has implicit casts from all basic integral types and explicit casts to/from all numeric type. To learn more about this type – please visit the BCL team blog.
    
  
  

• LINQ over XML (XLinq)
  
  • Enable further LINQ over XML feature support (in addition to the functionality available in the Oct 2006 CTP) such as the ability to apply XLST to transform into and out of XLinq trees, support for System.XML reader/writer interfaces for improved XML sharing with DOM applications and System.XML schema validation for XLinq nodes.
    
  
  

• SQL Server Compact Edition (SSCE)
  
  • SQL Server Compact Edition (SSCE) provides a local relational data store for occasionally connected client applications from desktops to devices. SSCE is light weight, embeddable and is easy to deploy with your client applications without requiring complex administration work from users. Timestamp (row version id) data type, improved table designer, Query processor enhancements and support for local transaction scope are some of the new features you find in this version of SSCE.
    
  
  

Thi CTP is available both as a regular install, and on a virtual machine.

How To Check If Any, ALL Or No Parameters Have A NULL Value

Let's say you have a procedure that accepts 6 parameters. depending on if these parameters are all null, all not null, some null and some not null you want to do different things.
How can you test this the easiest? This depends what you are testing for but COALESCE and concatenation are the easiest (read least to type) to do.


So let's start with all nulls
You can do a bunch of ANDs
You can concatenate into a string but you have to first set CONCAT_NULL_YIELDS_NULL OFF because the default CONCAT_NULL_YIELDS_NULL ON will return NULL if even one value is NULL
You can also union the parameters and do a NOT EXIST NOT NULL test
Finally you can use COALESCE which will return NULL if ALL the values are NULL


--ALL NULL
DECLARE @Param1 VARCHAR(10),
@Param2 VARCHAR(10),
@Param3 VARCHAR(10),
@Param4 VARCHAR(10),
@Param5 VARCHAR(10),
@Param6 INT


IF @Param1 IS NULL
AND @Param2 IS NULL
AND @Param3 IS NULL
AND @Param4 IS NULL
AND @Param5 IS NULL
AND @Param6 IS NULL
PRINT 'ALL NULL'

SET CONCAT_NULL_YIELDS_NULL OFF
IF (SELECT @Param1+ @Param2+ @Param3+ @Param4+ @Param5+ CONVERT(VARCHAR(10),@Param6)) IS NULL
PRINT 'ALL NULL'


IF NOT EXISTS (SELECT * FROM (SELECT @Param1 AS Param UNION ALL
SELECT @Param2 UNION ALL
SELECT @Param3 UNION ALL
SELECT @Param4 UNION ALL
SELECT @Param5 UNION ALL
SELECT CONVERT(VARCHAR(10),@Param6) ) X WHERE Param IS NOT NULL)
PRINT 'ALL NULL'



IF (SELECT COALESCE(@Param1,@Param2,@Param3,@Param4,@Param5,CONVERT(VARCHAR(10),@Param6))) IS NULL
PRINT 'ALL NULL'

Next up is to test that at least one value is not NULL
You can do a bunch of Ors
You can concatenate into a string but you have to first set CONCAT_NULL_YIELDS_NULL OFF because the default CONCAT_NULL_YIELDS_NULL ON will return NULL if even one value is NULL
You can also union the parameters and do a EXIST NOT NULL test
Finally you can use COALESCE which will not return NULL if ANY of the values is not NULL

--Some Non Nulls
DECLARE @Param1 VARCHAR(10),
@Param2 VARCHAR(10),
@Param3 VARCHAR(10),
@Param4 VARCHAR(10),
@Param5 VARCHAR(10),
@Param6 INT

SELECT @Param1 ='A'

SET CONCAT_NULL_YIELDS_NULL OFF
IF (SELECT @Param1+ @Param2+ @Param3+ @Param4+ @Param5+ CONVERT(VARCHAR(10),@Param6)) IS NOT NULL
PRINT 'At least One Value is not NULL'



IF @Param1 IS NOT NULL
OR @Param2 IS NOT NULL
OR @Param3 IS NOT NULL
OR @Param4 IS NOT NULL
OR @Param5 IS NOT NULL
OR @Param6 IS NOT NULL
PRINT 'At least One Not NULL'


IF EXISTS (SELECT * FROM (SELECT @Param1 AS Param UNION ALL
SELECT @Param2 UNION ALL
SELECT @Param3 UNION ALL
SELECT @Param4 UNION ALL
SELECT @Param5 UNION ALL
SELECT CONVERT(VARCHAR(10),@Param6) ) X WHERE Param IS NOT NULL)
PRINT 'At least One Not NULL'

IF (SELECT COALESCE(@Param1,@Param2,@Param3,@Param4,@Param5,CONVERT(VARCHAR(10),@Param6))) IS NOT NULL
PRINT 'At least One Not NULL'


Next up is to test that there are no NULLs
You can do a bunch of ANDs
You can also union the parameters and do a NOT EXIST NULL test
Finally you can use COALESCE which will not return NULL if ANY of the values is not NULL

--No NULLS
DECLARE @Param1 VARCHAR(10),
@Param2 VARCHAR(10),
@Param3 VARCHAR(10),
@Param4 VARCHAR(10),
@Param5 VARCHAR(10),
@Param6 INT

SELECT @Param1 ='A',
@Param2 ='A',
@Param3 ='A',
@Param4 ='A',
@Param5 ='A',
@Param6 =1


IF @Param1 IS NOT NULL
AND @Param2 IS NOT NULL
AND @Param3 IS NOT NULL
AND @Param4 IS NOT NULL
AND @Param5 IS NOT NULL
AND @Param6 IS NOT NULL
PRINT 'No NULLs'

IF NOT EXISTS (SELECT * FROM (SELECT @Param1 AS Param UNION ALL
SELECT @Param2 UNION ALL
SELECT @Param3 UNION ALL
SELECT @Param4 UNION ALL
SELECT @Param5 UNION ALL
SELECT CONVERT(VARCHAR(10),@Param6) ) X WHERE Param IS NULL)
PRINT 'No NULLs'


SET CONCAT_NULL_YIELDS_NULL ON
IF (SELECT @Param1+ @Param2+ @Param3+ @Param4+ @Param5+ CONVERT(VARCHAR(10),@Param6)) IS NOT NULL
PRINT 'No NULLs'

The final test is to test that at least one value is NULL
You can do a bunch of Ors
You can concatenate into a string and leave the default CONCAT_NULL_YIELDS_NULL ON because CONCAT_NULL_YIELDS_NULL ON will return NULL if even one value is NULL
You can also union the parameters and do a EXIST NOT NULL test

--Some Nulls
DECLARE @Param1 VARCHAR(10),
@Param2 VARCHAR(10),
@Param3 VARCHAR(10),
@Param4 VARCHAR(10),
@Param5 VARCHAR(10),
@Param6 INT


SELECT @Param1 ='A',
@Param2 ='A',
@Param3 ='A',
@Param4 =null,
@Param5 ='A',
@Param6 =1

IF @Param1 IS NULL
OR @Param2 IS NULL
OR @Param3 IS NULL
OR @Param4 IS NULL
OR @Param5 IS NULL
OR @Param6 IS NULL
PRINT 'At least One NULL'

SET CONCAT_NULL_YIELDS_NULL ON
IF (SELECT @Param1+ @Param2+ @Param3+ @Param4+ @Param5+ CONVERT(VARCHAR(10),@Param6)) IS NULL
PRINT 'At least One NULL'
ELSE
PRINT 'No NULLs'

IF EXISTS (SELECT * FROM (SELECT @Param1 AS Param UNION ALL
SELECT @Param2 UNION ALL
SELECT @Param3 UNION ALL
SELECT @Param4 UNION ALL
SELECT @Param5 UNION ALL
SELECT CONVERT(VARCHAR(10),@Param6) ) X WHERE Param IS NULL)
PRINT 'At least One NULL'
