Guess Who Gave This Answer In A Newsgroup?

Try to guess who gave this answer. Here is a small hint, the person looks like Anton Szandor LaVey

Question: I guess the key question for me is, can this be done entirely in SQL?


Answer: The answer is always "Yes, we can do it in SQL!"

The right answer is "But, like a size 26 thong, just because you can
does not mean you should!"


Google around for "Bin packing" and/or "Knapsack" problems on some math
websites. This is a known NP-complete problem. In English, it means
that the only way to solve it is to try all possible combinations, so
the execution time grows fastrer than any polynominal expression (i.e
think about factorials or worse).


There are often several valid solutions, too. Being a set-oriented
language, SQL will attempt to find the set of ALL solutions. And run
forever.


This is a job for a procedure (yes, [name here] is saying nice thing about
procedural code!) which will stop at the first usable answer, even if
it is not optimal. Now you have to pick your algorithm. This is
usually the Greedy algorithm ("grab the biggest bite you can and add it
to the answer; see if you met the goal; if not, repeat") modified to do
some back tracking.


So who gave this answer?

Sweet Child O' Mine By Guns N' Roses Or Child in Time By Deep Purple?

Yesterday we talked about Whole Lotta Love and whole Lotta Rosie today we are talking about Sweet Child O' Mine and Child In Time. So which is your favorite?

Sweet Child O' Mine by Guns N' Roses from the album Appetite for Destruction
Child in Time by Deep Purple from the album Deep Purple in Rock

This is a very tough pick for me because I love both songs but I would have to go for Sweet Child O' Mine. This song is perfect in every way from the vocals to the guitar solo to the introduction's famous D-flat based riff. The lyrics were written by Axl Rose as a love letter to his girlfriend at the time Erin Everly. No matter how many times I listen to the song it never bores me; something I can’t say about Paradise City; I just can’t stand that song anymore

Child in time is a song that is over 10 minutes long; It starts slowly with only an organ then builds up to a faster pace and then stops abruptly to start over again. Guitarist Ritchie Blackmore solo is just amazing and Ian Gillan’s voice goes from quiet singing to loud screaming. If you never heard this song I urge you to check it out.

Lyrically, the song is deep and dark; here are the lyrics:
Sweet child in time,
You'll see the line.
The line that's drawn between,
The good and the bad.
See the blind man,
He's shooting at the world.
The bullets flying,
Mmm... they're taking toll.
If you've been bad,
Lord I bet you have.
And youve not been hit,
You've not been hit by flying lead.
You'd better close your eyes,
You'd better bow your head.
Wait for the ricochet...


I have at least 3 versions of this song; the original, the live version from Made In Japan and the live version from Scandinavian Nights.

My favorite Guns N' Roses songs:
Mr. Browstone
Live and Let Die
Don't Cry
Civil War
Knockin' on Heaven's Door
You Could Be Mine
It's So Easy
Nightrain
Out Ta Get Me
Mr. Brownstone
My Michelle
Think About You
Sweet Child O' Mine
You're Crazy


My favorite Deep Purple songs:
Child In Time
Smoke On The Water
Hush
Soldier Of Fortune (David Coverdale is the singer on this one)
Speed King (the longer version with crazy guitar intro)

So which are your favorites?

sys.dm_db_session_space_usage

Okay so today we will talk about the sys.dm_db_session_space_usage dynamic management view.
This is the third dynamic management view that I have covered; a list if all of them and the date that I covered some of them can be found below

http://sqlservercode.blogspot.com/2006/08/dynamic-management-views-blog-post.html



Before we start here are a couple of remarks

IAM pages are not included in any of the allocation or deallocation counts reported by this view.

Page counters are initialized to zero (0) at the start of a session. The counters track the total number of pages that have been allocated or deallocated for tasks that are already completed in the session. The counters are updated only when a task ends; they do not reflect running tasks.

A session can have multiple requests active at the same time. A request can start multiple threads, tasks, if it is a parallel query.

Here is some information about the columns in this view

session_id
smallint
Session ID.
-- session_id maps to session_id in sys.dm_exec_sessions.

database_id
smallint
Database ID.

user_objects_alloc_page_count
bigint
Number of pages reserved or allocated for user objects by this session.

user_objects_dealloc_page_count
bigint
Number of pages deallocated and no longer reserved for user objects by this session.

internal_objects_alloc_page_count
bigint
Number of pages reserved or allocated for internal objects by this session.

internal_objects_dealloc_page_count
bigint
Number of pages deallocated and no longer reserved for internal objects by this session.


First we will talk about user objects

User Objects
The following objects are included in the user object page counters:

• User-defined tables and indexes
  
• System tables and indexes
  
• Global temporary tables and indexes
  
• Local temporary tables and indexes
  
• Table variables
  
• Tables returned in the table-valued functions
  

SELECT *
FROM sys.dm_db_session_space_usage
WHERE session_id = @@spid


Values in the columns
--------------------------------------
user_objects_alloc_page_count =0
user_objects_dealloc_page_count = 0
internal_objects_alloc_page_count = 0
internal_objects_dealloc_page_count = 0




CREATE TABLE #temp(id VARCHAR(MAX))
INSERT #TEMP VALUES(REPLICATE('a',25000))
INSERT #TEMP VALUES(REPLICATE('b',25000))
INSERT #TEMP VALUES(REPLICATE('c',25000))
INSERT #TEMP VALUES(REPLICATE('d',25000))
INSERT #TEMP VALUES(REPLICATE('e',25000))

SELECT *
FROM #temp

SELECT *
FROM sys.dm_db_session_space_usage
WHERE session_id = @@spid

user_objects_alloc_page_count =5
user_objects_dealloc_page_count = 0
internal_objects_alloc_page_count = 0
internal_objects_dealloc_page_count = 0

DROP TABLE #temp

SELECT *
FROM sys.dm_db_session_space_usage
WHERE session_id = @@spid


Values in the columns
--------------------------------------
user_objects_alloc_page_count =5
user_objects_dealloc_page_count = 5
internal_objects_alloc_page_count = 0
internal_objects_dealloc_page_count = 0


CREATE TABLE #temp(id VARCHAR(MAX))
INSERT #TEMP VALUES(REPLICATE('a',25000))
INSERT #TEMP VALUES(REPLICATE('b',25000))
INSERT #TEMP VALUES(REPLICATE('c',25000))
INSERT #TEMP VALUES(REPLICATE('d',25000))
INSERT #TEMP VALUES(REPLICATE('e',25000))


SELECT *
FROM #temp

SELECT *
FROM sys.dm_db_session_space_usage
WHERE session_id = @@spid


Values in the columns
--------------------------------------
user_objects_alloc_page_count =10
user_objects_dealloc_page_count = 5
internal_objects_alloc_page_count = 0
internal_objects_dealloc_page_count = 0


TRUNCATE TABLE #temp

SELECT *

user_objects_alloc_page_count =10
user_objects_dealloc_page_count = 10
internal_objects_alloc_page_count = 0
internal_objects_dealloc_page_count = 0



DROP TABLE #temp1


so those were the use objects now we will talk about internal objects

Internal Objects
Internal objects are only in tempdb. The following objects are included in the internal object page counters:

• Work tables for cursor or spool operations and temporary large object (LOB) storage
  
• Work files for operations such as a hash join
  
• Sort runs
  

--Create the tables
CREATE TABLE #temp1(id INT, SomeCol VARCHAR(MAX))
INSERT #TEMP1 VALUES(1,REPLICATE('a',25000))
INSERT #TEMP1 VALUES(2,REPLICATE('b',25000))
INSERT #TEMP1 VALUES(3,REPLICATE('c',25000))
INSERT #TEMP1 VALUES(4,REPLICATE('d',25000))
INSERT #TEMP1 VALUES(5,REPLICATE('e',25000))


CREATE TABLE #temp2(id INT, SomeCol VARCHAR(MAX))
INSERT #TEMP2 VALUES(1,REPLICATE('a',25000))
INSERT #TEMP2 VALUES(2,REPLICATE('b',25000))
INSERT #TEMP2 VALUES(3,REPLICATE('c',25000))
INSERT #TEMP2 VALUES(4,REPLICATE('d',25000))
INSERT #TEMP2 VALUES(5,REPLICATE('e',25000))


--Do a sort operation
SELECT *

JOIN #TEMP1 t1 ON t1.id = t2.id
ORDER BY t1.id,t1.SomeCol,t2.id,t2.SomeCol


--Check the view
SELECT *

WHERE session_id = @@spid


Values in the columns

user_objects_alloc_page_count =20
user_objects_dealloc_page_count = 10
internal_objects_alloc_page_count = 16
internal_objects_dealloc_page_count = 8


What is this dmv useful for? You can use it to to help you diagnose and troubleshoot problems caused by insufficient disk space in the tempdb database.

The following error messages indicate insufficient disk space in the tempdb database. These errors can be found in the SQL Server error log, and may also be returned to any running application.

1101 or 1105
Any session must allocate space in tempdb.

3959
The version store is full. This error usually appears after a 1105 or 1101 error in the log.

3967
The version store is forced to shrink because tempdb is full.

3958 or 3966
A transaction cannot find the required version record in tempdb.


Some of these queries that you can use can be found here: Troubleshooting Insufficient Disk Space in tempdb

Whole Lotta Rosie By AC/DC or Whole Lotta Love By Led Zeppelin?

I got a new MP3 player from my sister in law for Christmas and have been listening to some good old R & R

So the question is which of these similar named songs do you prefer?
Whole Lotta Rosie by AC/DC with Bon Scott from the album Let There Be Rock.
Whole Lotta Love by Led Zeppelin from the album Led Zeppelin II.

Between these two my pick is Whole Lotta Rosie by AC/DC and I think that this is still my favorite AC/DC song.

My favorite Led Zeppelin song is not Whole Lotta Love but one of these
Since I've Been Loving You from Led Zeppelin III
Black Dog from Led Zeppelin IV
Over the Hills and Far Away from Houses of the Holy
Travelling Riverside Blues from the Led Zeppelin Box Set

I am still undecided on the Led Zep favorite. Which is your favorite Led Zep song? And no Stairway to Heaven is not allowed as your pick

Display 1 When Any Column Is 1 And 0 Otherwise by Using SIGN, SUM Or (Bitwise OR)

You have three columns; if any of the columns is 1 you want to display 1 if they are all 0 you want to display 0. how can you do that?
there are basically three ways to do this
1 SUM
2 SIGN
3 | (Bitwise OR)


Here are the examples

--create table and insert rows
CREATE TABLE #test (test_A INT,test_B INT,test_C INT)

INSERT INTO #test VALUES(0,0,0)
INSERT INTO #test VALUES(1,0,0)
INSERT INTO #test VALUES(0,1,0)
INSERT INTO #test VALUES(0,0,1)
INSERT INTO #test VALUES(0,1,1)
INSERT INTO #test VALUES(1,1,1)



First we will display 0 if all columns are 0; if any of the columns is 1 then we will display a one

--Using SIGN
SELECT SIGN(test_A+test_B+test_C) ,*
FROM #test

--Using (Bitwise OR)
SELECT (test_A | test_B | test_C),*
FROM #test

--Using Sum
SELECT CASE SUM(test_A + test_B + test_C)
WHEN 0 THEN 0 ELSE 1 END, *
FROM #test
GROUP BY test_A , test_B , test_C


Now let's say we want to display 1 if all the values are 1.
we can do that by using &; this is the Bitwise AND operator
--Using (Bitwise AND)
SELECT (test_A & test_B & test_C),*
FROM #test

-- SUM can also be used
SELECT CASE SUM(test_A + test_B + test_C)
WHEN 3 THEN 1 ELSE 0 END, *
FROM #test
GROUP BY test_A , test_B , test_C


Now let's reverse the process and display 0 if any of the columns are 1 and 1 if all the columns are 0.
We have to use CASE to accomplish this

--Using CASE with SIGN
SELECT CASE SIGN(test_A+test_B+test_C)
WHEN 1 THEN 0 ELSE 1 END, *
FROM #test

--Using CASE with Bitwise OR
SELECT CASE (test_A | test_B | test_C)
WHEN 1 THEN 0 ELSE 1 END, *
FROM #test


--Using SUM with CASE
SELECT CASE SUM(test_A + test_B + test_C)
WHEN 0 THEN 1 ELSE 0 END, *
FROM #test
GROUP BY test_A , test_B , test_C


Here is some additional stuff, add this row and run the queries again
INSERT INTO #test VALUES(1,NULL,1)

What happens when you run this?

SELECT SIGN(test_A+test_B+test_C) ,*
FROM #test

A NULL is returned; If you have NULLS in your table then you might want to use COALESCE

SELECT SIGN(test_A+COALESCE(test_B,0)+test_C) ,*
FROM #test

SQL Server 2005 Will Be Supported On Vista And Windows Server Longhorn

Don't get scared of those people at Badvista.org

Microsoft announced on September 27, 2006 that SQL Server 2005 would be supported on Vista This is just more FUD from Stallman & Co. However you must have service Pack 2 installed for it to run. From the site:

"In an effort to provide customers with more secure products, Microsoft Windows Server "Longhorn" and Microsoft Windows Vista will only support SQL Server 2005 Service Pack 2 (SP2) or later when it becomes available. Earlier versions of SQL Server, including SQL Server 2000 (all editions including Desktop Engine edition, a.k.a MSDE), SQL Server 7.0, and SQL Server 6.5, will not be supported on Windows Server "Longhorn" or Windows Vista. Customers running applications with these earlier versions of SQL Server should consider evaluating and upgrading to SQL Server 2005, which was designed to take advantage of the upcoming security and performance enhancements in the operating environment."

How Well Do You Interview And Do You Use Wizard Driven Programming?

We were interviewing people for developer and architect positions. The developer position required about 5 years C# and SQL Server. We got a couple of good candidates but some of them were really terrible. They claim SQL server experience since 1998 but don't know what a clustered index is or they can not name even one isolation level. There were people who had 10 years experience in web development but could not explain what MVC (Model-view-controller) is or name a design pattern. People created webservices but did not know what a WSDL is?????

You see this is the problem I have with WDP (Wizard Driven Programming); It's okay to use wizards but you HAVE to know what is going on behind the scenes. It's okay to use Enterprise Manager but you have to know how to do the same thing in Query Analyzer. If you never write your own scripts you will sooner or later come to a shop where they don't use these tools and changes have to be submitted via scripts. Not only do you have to script everything you also have to provide back-out scripts in case something goes wrong.

So here are some of the questions I asked; with 5 years experience I think you should not miss more than two (probably traceflag 1204 and parameter sniffing questions)

Let me know how many you couldn't get without looking them up

How do you return a varchar value from a proc
If I have a column that will only have values between 1 and 250 what data type should I use
How do you enforce that only values between 1 and 10 are allowed in a column
How to check for a valid date
Which date format is the only safe one to use when passing dates as strings
How do you suppress rows affected messages when executing an insert statement
Can you name the 4 isolation levels in SQL Server 2000

BadVista: The Worst FUD You Will Ever Read.... St. Ignucious Has Gone Wild

Richard Stallman (RMS, St. Ignucious ) is at it again. let's see what the site says:

The Free Software Foundation (FSF) today launched BadVista.org, a campaign
with a twofold mission of exposing the harms inflicted on computer users by the
new Microsoft Windows Vista and promoting free software alternatives that
respect users' security and privacy rights.
“Vista is an upsell masquerading
as an upgrade. It is an overall regression when you look at the most important
aspect of owning and using a computer: your control over what it does. Obviously
MS Windows is already proprietary and very restrictive, and well worth
rejecting. But the new 'features' in Vista are a Trojan Horse to smuggle in even
more restrictions. We'll be focusing attention on detailing how they work, how
to resist them, and why people should care”, said FSF program administrator John
Sullivan.

More interesting is the piece of garbage that they link to: 25 Shortcomings Of Vista

Here are some of the 'gems'

1. SMB2: Vista introduces a new variant of the SMB protocol called SMB2, which may pose problems for those connecting to non-Microsoft networks, such as Samba on Linux.
--Speculation and pure FUD

7. Five Versions: The array of Vista editions could prove to be three too many, and upgrades between versions remain an unknown.
8. Activation: The need to activate the product via the Web could prove to be a time-waster during mass deployments.
--Could prove? Could prove? Who writes this stuff? For mass deployments there is something called Key Management Service

Key Management Service
Your organization can host the Key Management Service (KMS) internally to automatically activate computers running Windows Vista. To use the KMS, you must have a minimum of 25 computers running Windows Vista that are connected together. Computers that have been activated through KMS will be required to reactivate by connecting to your organization's network at least every six months.

Currently the KMS software runs on a local computer running Windows Vista or the Microsoft Windows Server Code Name "Longhorn" operating system. In the future, it will run on the Microsoft Windows Server 2003 operating system.

9. Storage Space: With Vista taking as much as 10 Gbytes of hard drive space, big and fast hard drives will be a must.
--Last time I checked you can't really buy anything less than 100GB

10. Backup: See No. 9. Backing up desktops will take a great deal of space.
--So backup only your personal data.

18
Buried Controls
Many options and controls are further buried, requiring a half-dozen mouse clicks or more to get to. Network settings and display settings are offenders here.
--Some people said the same thing in WinXP, until they realized there is also a classic view. Vista has this classic view also.

19. Installation Can take hours on some systems. Upgrades are even slower.
--This is BS; it should not take more than 30 minutes unless you got a pirated copy on 1500 floppy discs

20. HHD Hybrid Hard Drives. These are potentially a huge performance booster, but there's little information and support is available (even though should be available).
--Since when is having an emerging technology that will boost performance a shortcoming?

#25:
WordPadAbility to open .doc files has been removed.
--Hahahahahaha who wrote this piece of crap. You either use Word or OpenOffice

Three Ways To Display Two Counts From a Table Side By Side

This question came up on tek-tips.

I want to count the CA and the UT states from the authors table and output this in different columns named CaCount and UtCount

CaCount UtCount
----------- -----------
15 2


How do you do such a thing? To display the following is very easy

state StateCount
----- -----------
CA 15
UT 2

You just do a count and group by

SELECT state,COUNT(*) AS StateCount
FROM authors
WHERE state in ('CA', 'UT')
GROUP BY state


How do we display them side by side? We can do this 3 different ways
1 stick the count in variables
2 run the count twice a s a separate query
3 sum with case

USE PUBS
GO

--stick the count in variables
DECLARE @UtCount INT
DECLARE @CaCount INT

SELECT @UtCount = COUNT(*) FROM authors WHERE state ='UT'
SELECT @CaCount = COUNT(*) FROM authors WHERE state ='CA'

SELECT @CaCount AS CaCount,@UtCount AS UtCount

--run the count twice as a separate query
SELECT (SELECT COUNT(*) FROM authors
WHERE state ='CA') AS CaCount,
(SELECT COUNT(*) FROM authors WHERE state ='UT') AS UtCount


--sum with case
SELECT SUM(CASE state WHEN 'CA' THEN 1 ELSE 0 END) AS CaCount,
SUM(CASE state WHEN 'UT' THEN 1 ELSE 0 END) AS UtCount
FROM authors


If you look at the execution plan then you will see that the best option is the third one (sum with case). The third option only queries the table once instead of twice like the other two solutions and will thus be twice as fast
So keep that in mind when you have to do such a query next time

[edit]
Oracle Version
jbjornson left the Oracle version in a comment; I decided to add it to the post. I don't know about the syntax coloring on Oracle/TOAD so you are getting a black and white only ;-(

--run the count twice as a separate query
SELECT CA.caCount, UT.UtCount
FROM (SELECT COUNT(*) as CaCount FROM authors) WHERE state ='CA') CA,
(SELECT COUNT(*) FROM authors WHERE state ='UT') UT


--sum with case
SELECT SUM(decode(state, 'CA', 1, 0)) AS CaCount,
SUM(decode(state, 'UT', 1, 0)) AS UtCount
FROM authors

Index Build Strategy In SQL Server

The Tips, Tricks, and Advice from the SQL Server Query Processing Team blog has 3 really good posts about Index Build strategy in SQL Server. You should definitely read these to really understand how to implement that. Here are the links:
Index Build strategy in SQL Server - Part 1: offline, serial, no partitioning

Index Build strategy in SQL Server - Part 2: Offline, Parallel, No Partitioning

Index Build strategy in SQL Server - Part 2: Offline, Parallel, No Partitioning (Non stats plan (no histogram))

Problems With ROW_NUMBER() In A WHERE Clause

This is a question that came up today. A person had a query like this


USE AdventureWorks
GO

SELECT
ROW_NUMBER() OVER (ORDER BY addressline1) AS rowNum,
addressline1,
city
FROM person.address
WHERE rowNum > 3;

That gave the following error
Server: Msg 207, Level 16, State 1, Line 6
Invalid column name 'rowNum'.

What you have to do is use Common Table Expressions or use a subquery. Below are both methods.

--Subquery
SELECT * FROM ( SELECT
ROW_NUMBER() OVER (ORDER BY addressline1) AS rowNum,
addressline1,
city
FROM person.address) AS x
WHERE rowNum > 3;


--CTE
WITH x (rowNum,addressline1,
city) AS
(SELECT
ROW_NUMBER() OVER (ORDER BY addressline1) AS rowNum,
addressline1,
city
FROM person.address)

SELECT * FROM X
WHERE rowNum > 3;

Wedding Anniversary

So here we are 9 years later. We are still married have 3 kids and bought our second home this year. So let me give you a little background of how I met my wife etc etc. I met my wife in a bar on the upper eastside in New York City.
I don’t remember the name of the bar but I do remember that we went to Elaine’s for a drink and also to a place named the Cowboy Bar. Fast forward to the wedding date; we got married twice first at City Hall on December 11th and then we did a church wedding on August 15th (the pictures are from that day) We did the December wedding separately so that we could start my Green Card process; my wife is a third generation Italian-American but I had Dutch and Croatian citizenships.

The wedding was 1 block from were we lived. My wife (to be) spent the night in a hotel with her sisters. The wedding started at 3; I was still rollerblading till 2:30 in Central Park. I took a shower got dressed and walked to the church (which was 1 block from my apartment)

5% of the wedding guests did jail time.
The reception was held at the Kitano Hotel which is located at 38th and Park Avenue. I did not have a huge wedding only 65 or so family members and some of our closest friends were invited. Out of those people there were 3 who did some jail time. One of them is Brendan who was the head of the NYC Hells Angels chapter at that time.

Another was brought by a friend and the last one was a friend of mine who did jail time because he beat up a cop. The Hells Angel did not dress up of course, if you look at the picture you can see me next to my wife. The other picture is me and my wife on the roof. The reception had 2 huge balconies; one was facing the Empire State Building and the other one was facing the Chrysler Building. The good thing when having your wedding at a hotel is that you can just walk to your room.


Honeymoon in Hawaii
So after the reception we had two days to get ready for the honeymoon. We did our shopping and on Monday night we went to China Club with out friend from Europe. China Club is the place to go to on Mondays; you can always spot some model or one of the Yankees or Knicks there. The next day we went to Maui and Kuai. I have said many times to my wife that I want to go back to Hawaii once before I die…. Maui and Kuai were beautiful places to spend your honeymoon; if you are into playing golf, surfing, hiking, snorkeling then there are lots of things to do here. Jurassic Park was shot in Kuai and once you arrive in Kuai you will recognize the green scenery right away

After the honeymoon
Once you are married don’t have kids right away; your live will change and you won’t be able to do anything for a while. So that is what we did; we waited 4 years to have kids. We visited Paris and Amsterdam and bought a house near Princeton before having our first son Christian. Then my wife became pregnant with twins and we had to sell our house and buy a bigger house. If owing you house is the American Dream then selling and buying your next house has to be the American Nightmare; what a stressful situation. After that ordeal I said that the next time I move will be in one of those 55+ community houses (I still have about 20 years to go). So today we live in Princeton and we have Catherine and Nicholas to keep us awake at night.


Traditions
My wife and I usually buy our Christmas tree on our anniversary. In the city we would pick up a Charlie Brown on 2nd avenue and 79th street; out here we go to the farm and chop down our own. Somehow my wife thinks it is also a tradition to watch Serendipity; if I have to watch a movie with Kate Beckingsale I prefer Underworld but hey you have to be nice on your anniversary….


BTW I still fit in my wedding suit, the tailor was wrong ;-(

Plan For The Day…Gone Wrong In a Big Way

It is my 9th year wedding anniversary this weekend so I took the day off today and below is a list of things I planned to do today

[ ] Get a Christmas tree at the farm
[ ] Go for breakfast with the whole family
[ ] Drop of a package at the post office
[X] Interview a person for a position at work
[ ] Enhance a Stored Procedure and close the item in BugTrax
[ ] Watch Serendipity (my wife insists)
[ ] Get haircuts
[X] Cover the furniture in the garden

As you can see I managed to accomplish two things only so far. What happened? My son got sick and had a high fever and threw up this morning; that eliminated the first 3 items right away. I managed to do the phone interview because it was a reversed phone interview (the candidate was at the office and I interviewed him from home over the phone)
Forget about the haircuts (I rescheduled for tomorrow); where do I leave our 3 kids?
So that leaves me with watching Serendipity tonight ;-(

Anyway I will post something about my wedding this weekend. Believe it or not 5% of the people that came to my wedding did jail time; one of them was the head of the NYC Hells Angels chapter( I will also post some pictures this weekend)


Oh you wanted some SQL material? No problem this will keep you busy for a while ;-)

Get The Domain Name Of Your SQL Server Machine

How do you get the domain name that your SQL Server machine belongs to with T-SQL code?

You can use the undocumented procedure xp_regread; I have tested this on SQL Server 2005 and on SQL Server 2000.
Be advised that since this is an undocumented procedure that it might not be available in the future or it might be changed either because of a service pack or a hot fix. Don't use it as production code!

Here is how to do this

DECLARE @chvDomainName NVARCHAR(100)
EXEC master.dbo.xp_regread 'HKEY_LOCAL_MACHINE',
'SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon',
N'CachePrimaryDomain',@chvDomainName OUTPUT

SELECT @chvDomainName AS DomainName
