Puzzle: Friday the Thirteenths

There is a puzzle on LessThanDot

The goal is to identify all friday the thirteenths for a given timeframe. We'll use a relatively small number of years, like 10. This should make it a little easier in procedural languages.

I posted my SQL solution, what about you?

Go here: Friday the Thirteenths and show me what you got. Make sure to use the [hide][/hide] tags so you don't spoil it for other people

Less Than Dot A New community Site Has Been Launched

Myself and a bunch of friends have been working on Less Than Dot for a while now. The site has a forum, blogs and a wiki. More info why we started Less Than Dot and who we are can be found here: http://www.lessthandot.com/aboutus.php

Since I am mostly a SQL guy, I wrote a collection of SQL Server hacks. This collection of SQL hacks is available on the Wiki, right now we have 8 sections and between 70 and 80 hacks. Ideally we will have more hacks and we will also have a SQL admin hacks page in the future.

SQL Server Hacks Sections
* 1 NULLS
* 2 Dates
* 3 Sorting, Limiting Ranking, Transposing and Pivoting
* 4 Handy tricks
* 5 Pitfalls
* 6 Query Optimization
* 7 Undocumented but handy
* 8 Usefull Admin stuff For The Developer


Below are some direct links to a couple hacks, you can also get a list of all the hacks on the wiki itself here: SQL Server Programming Hacks

Trouble With ISDATE And Converting To SMALLDATETIME
Row To Column (PIVOT)
Column To Row (UNPIVOT)

Hopefully you will like the site and find some good content, if you have a question then don't hesitate to ask it in a forum.

SQL Teaser uniqueidentifier

Create this table

CREATE TABLE #bla (SomeVal uniqueidentifier)
INSERT #bla VALUES('D903D52D-DBFA-4904-9D95-F265152A391F')

what do you think this will return?


SELECT * FROM #bla
WHERE SomeVal = 'D903D52D-DBFA-4904-9D95-F265152A391F12345678910'
UNION ALL
SELECT * FROM #bla
WHERE SomeVal = 'D903D52D-DBFA-4904-9D95-F265152A391F1'

Surprised?

What about this?

SELECT * FROM #bla
WHERE SomeVal = CONVERT(uniqueidentifier,'D903D52D-DBFA-4904-9D95-F265152A391F12345678910')

I have a question for you on DB development blunders!

Last week Kalen Delaney wrote Did You Know? I have a question for you on DBA Blunders! I though the comments were very interesting, S we did the DBA part but what about developers? What are some of the worst blunders you have seen?

Here are a couple of things

Starting a begin tran, then some insert/update command, never commiting but minimizing the window.


Here is my all time favorite, can you reduce this by 90%?


declare @Token int
select @Token = 51234567

declare @val int


if left(@Token,1) = 1
select @val = 1
else if left(@Token,1) = 2
select @val = 2
else if left(@Token,1) = 3
select @val = 3
else if left(@Token,1) = 4
select @val = 4
else if left(@Token,1) = 5
select @val = 5
else if left(@Token,1) = 6
select @val = 6
else if left(@Token,1) = 7
select @val = 7
else if left(@Token,1) = 8
select @val = 8
else if left(@Token,1) = 9
select @val = 9
else if left(@Token,1) = 0
select @val = 0


select @val


Actually we put that on the whiteboard after we found it in our code and every time the developer wanted something we teased him about it...Oh you mean like that (pointing to the whiteboard)


What about changing the datatype from smallint to int in the table but keeping the params smallint in the proc.....mmmm why do I get a conversion in the execution plan?





So let's here some of what you have seen others write, we all know we couldn't write stuff like that ourselves right? :-)

Spring Cleaning, Getting Rid Of Some Books

I did some spring cleaning yesterday, I got rid of some old or obsolete books. I asked some people at work if they want any of these books and I believe all the books except for the JCL book are about to be given away.

I got rid of these books because:
I got a new version
I don't use the technology anymore
The book is obsolete

How to log when a function is called?

This question came up today and here is one way of doing it. It requires running xp_cmdshell so this is probably not such a good idea.
The problem with functions is that you cannot just insert into any table. INSERT, UPDATE, and DELETE statements modifying table variables local to the function.
EXECUTE statements calling an extended stored procedures are allowed.
So with this in mind we know that we can call xp_cmdshell, from xp_cmdshell we can use osql
Let's take a look
We will be using tempdb


--Create the table
USE tempdb
go
CREATE TABLE LogMeNow (SomeValue varchar(50), SomeDate datetime default getdate())
go

--Here is the proc
CREATE PROC prLog
@SomeValue varchar(50)
AS
INSERT LogMeNow (SomeValue) VALUES(@SomeValue)
go

--And here is the function
CREATE FUNCTION fnBla(@id int)
RETURNS int
AS
BEGIN
DECLARE @SQL varchar(500)
SELECT @SQL = 'osql -S' +@@servername +' -E -q "exec tempdb..prLog ''fnBla''"'
EXEC master..xp_cmdshell @SQL
RETURN @id
END

Now call the function a couple of times

SELECT dbo.fnBla(1)
SELECT dbo.fnBla(2)
SELECT dbo.fnBla(4)

And look inside the table

SELECT * FROM LogMeNow

What if you were to run this?

SELECT dbo.fnBla(4),* FROM sys.sysobjects

See the problem? The function will be called for every row, if you have a big table this can be problematic!!!!!!!!

I tested this on SQL 2000 and on SQL 2005(including a named instance). So there you have it, this is one way. does it smell kludgy and do I feel somewhat dirty now? yes it does indeed :-(

SQL Teaser: @@ROWCOUNT

Without running this what do you think will be printed?


SET ROWCOUNT 0
DECLARE @ int
SET @ =6
IF @@ROWCOUNT = 1
PRINT 'yes'
ELSE
PRINT 'no'
PRINT @@rowcount

Should SQLServer Have The CREATE [OR REPLACE] PROCEDURE Syntax?

I was asked by a developer at work the other day why SQL Server does not have the create or replace syntax. I started thinking and there were some advantages and one big disadvantage

First the advantages

Advantage
When scripting out a database you don’t have to generate if exists.....drop statements

When modifying an object from a file in source control you don’t have to change back and forth between CREATE and ALTER. This is really annoying sometimes; usually you create a proc or script out a proc and store it in Subversion/SourceSafe. Now you take that file, make some changes to the proc and run it. Of course it will tell you that the proc already exists, in general you don’t want to drop the proc and then execute the CREATE proc statement because then you have to worry about the permissions.(not everyone is running as dbo you know)

Disadvantage
I can overwrite a proc without even knowing it. What if we both are working on a proc and somehow we pic the same name I create my proc, you work in a remote location, you create yours and mine is gone.

Of course it is all what you are used to, I am sure the Oracle guys are not overwriting each other’s procs every day either

So what do you think? Would you be in favor of this syntax or not? Can you think of more advantages or disadvantages?

What Would You Like To Ask Erland Sommarskog?

In the Who do you want to see interviewed next?(sqlblog) and Who do you want to see interviewed next?(here) blog post I asked for some names of people who YOU would like to see interviewed. Erland Sommarskog's name was submitted in comments a couple of times. I contacted Erland and am happy to anounce that he has agreed to do this.

The first time I heard of Erland Sommarskog was in the SQL Server programming newsgroups. I also read all the articles on his site. When I answer questions I usually give the link out to these 4 articles
Arrays and Lists in SQL Server
Implementing Error Handling with Stored Procedures
Error Handling in SQL Server – a Background
and of course The curse and blessings of dynamic SQL

I always wondered why he didn't write a SQL book. Hey, now I can ask him that :-)

Before you think of any questions please visit Erland's page first (http://www.sommarskog.se/index.html) and read some of the articles he wrote.

You can submit questions until Monday May 12th and then I will forward the questions to Erland.

What Would You Like To Ask Craig Freedman?

In the Who do you want to see interviewed next?(sqlblog) and Who do you want to see interviewed next?(here) blog post I asked for some names of people who YOU would like to see interviewed. Craig Freedman's name was submitted in comments a couple of times. I contacted Craig and am happy to anounce that he has agreed to do this.

Before you think of any questions please visit Craig's blog first(http://blogs.msdn.com/craigfr/) to get a feel of what kind of questions to ask. It would make sense to keep the questions focused on query processing, query execution, and query plans. I told Craig that if he doesn't like a question that he does not have to answer it.

You can submit questions until Monday May 12th and then I will forward the questions to Craig
