SQL Server 2008 To RTM In Q3 2008

Francois Ajenstat on his blog writes that

"Microsoft is excited to deliver a feature complete CTP during the Heroes Happen Here launch wave and a release candidate (RC) in Q2 calendar year 2008, with final Release to manufacturing (RTM) of SQL Server 2008 expected in Q3."

You can read the whole blog post here: http://blogs.technet.com/dataplatforminsider/archive/2008/01/25/microsoft-sql-server-2008-roadmap-clarification.aspx

Tip: Find all The Rows Where Any Of The Columns Is Null Or Zero Or Both

This question is asked every now and then so I decided to do a little blog post. How can you quickly without writing a bunch of OR statements determince if any columns have a NULL value, a value of 0 or if the value is 0 or NULL.
To test for NULL is very easy, you just concatenate the columns since NULL + anything else is always NULL. Okay that also depends on a setting.

Run this

SET CONCAT_NULL_YIELDS_NULL ON
SELECT NULL + '1' --NULL

SET CONCAT_NULL_YIELDS_NULL OFF
SELECT NULL + '1' --1

As you can see if CONCAT_NULL_YIELDS_NULL is OFF then the result is 1

Now take a look at this


SET CONCAT_NULL_YIELDS_NULL ON
SELECT NULL + 1 --NULL



SET CONCAT_NULL_YIELDS_NULL OFF
SELECT NULL + 1 --NULL


So with numeric values it behaves differently. Either way by default CONCAT_NULL_YIELDS_NULL is set to on
To test for NULLS or zeroes you use NULLIF
To test for zeros you can combine COALESCE and NULLIF

Here is the code which shows all of that

CREATE TABLE #test(column1 int,column2 varchar(4),column3 float)

INSERT #test VALUES(2,'2',2)
INSERT #test VALUES(0,'1',0)
INSERT #test VALUES(null,'1',0)
INSERT #test VALUES(1,null,0)
INSERT #test VALUES(0,'1',null)
INSERT #test VALUES(null,null,null)



--Any column is Null
SELECT * FROM #test
WHERE column1 + column2+column3 is null

Output
------------
NULL 1 0.0
1 NULL 0.0
0 1 NULL
NULL NULL NULL



--Any column is Null or zero
SELECT * FROM #test
WHERE NULLIF(column1,0) + NULLIF(column2,0)+NULLIF(column3,0) is null

Output
-------------------
0 1 0.0
NULL 1 0.0
1 NULL 0.0
0 1 NULL
NULL NULL NULL




--Any column is zero
SELECT * FROM #test
WHERE NULLIF(COALESCE(column1,1),0) +
NULLIF(COALESCE(column2,1),0)+
NULLIF(COALESCE(column3,1),0) is null

Output
-------------------
0 1 0.0
NULL 1 0.0
1 NULL 0.0
0 1 NULL


DROP TABLE #test

Has Anyone Succeeded In Creating A Collision Between NEWID and NEWSEQUENTIALID

SQL Server 2005 introduced a new type of function to create a uniqueidentifier; the NEWSEQUENTIALID(). This new function has been created for performance reasons, each new value is greater than the previous value. In theory this means that the value will be inserted at the end of a page and not in the middle which can cause splits.

Let's run this code to see the difference

CREATE TABLE #TableSeqID (ColumnA uniqueidentifier DEFAULT NEWSEQUENTIALID(),
ColumnB uniqueidentifier DEFAULT NEWID())

INSERT #TableSeqID DEFAULT VALUES
INSERT #TableSeqID DEFAULT VALUES
INSERT #TableSeqID DEFAULT VALUES
INSERT #TableSeqID DEFAULT VALUES
INSERT #TableSeqID DEFAULT VALUES
GO


SELECT * FROM #TableSeqID

Output
-----------
BBF765FE-57BD-DC11-875F-000D5684F8D8 CE51B9E4-1640-47E2-87C6-6ADD46C63A87
BCF765FE-57BD-DC11-875F-000D5684F8D8 CA220BAB-462E-440E-829A-E0037CAF0D1F
BDF765FE-57BD-DC11-875F-000D5684F8D8 01748772-8155-4F83-A58F-CC3253DDD3F3

As you can see ColumnB is random (Or at least pseudo-random) while ColumnA is not
Let's say you have a table with a billion rows, this table used NEWID() up till now. What will happen when you change the table to use NEWSEQUENTIALID(), could you get a duplicate?
I tried my best and filled up my 400GB External Seagate drive without success

Have you run into a collision, is it even possible?

Use the *1 trick to do math with two varchars, this prevents the Invalid operator for data type. Operator equals subtract,type equals varchar message

Someone had code like this on the tek-tips forum

DECLARE @v varchar(24)
SELECT @v ='06029202400250029'

SELECT RIGHT(@v,4) -SUBSTRING(@v,10,4)

If you run this code, you will get the following message
Server: Msg 403, Level 16, State 1, Line 4
Invalid operator for data type. Operator equals subtract, type equals varchar.

Instead of casting to integers you can also use this little trick. You basically multiply one of the values by 1

DECLARE @v varchar(24)
SELECT @v ='06029202400250029'

SELECT RIGHT(@v,4) *1 -SUBSTRING(@v,10,4)



Another example. This doesn't work
SELECT '2' - '1'

This does work
SELECT '2' * 1 - '1'

A year in review, The 21 + 1 best blog posts on SQLBlog

These are the best posts according to me, it might have been the content or it might have been the comments. Either way here are the 21 + 1 posts I enjoyed the most. But wait the year is not over yet. Doesn't matter no one will write anything good till next year anyway (prove me wrong and I WILL update this post).

The first post is really from last year, I mean really, who writes a post on '2006-12-31T13:49:00.000' (yes that is ISO8601)? Since I did not see the post until 2007 I have included it in the list. I tried not to include more than 2 or 3 posts per blogger, I would have included all Hugo's NULL posts otherwise. What is with the 21 + 1 title? The +1 one is my post about using bitwise logic, it is the last link

Below is the list, let me know if I missed anything you really enjoyed and Happy New Year

Screencast: SQL Server 2008 Change data capture

CDC or Change data capture is a new feature in SQL Server 2008, which is an ability to record changes to table data into another table without writing triggers or some other mechanism, Change data capture records the changes like insert, update, and delete to a table in SQL server thus making the details of the changes available in relational format.

Use XACT_STATE() To Check For Doomed Transactions

Let's say you have the following transaction

BEGIN TRANSACTION TranA
BEGIN TRY
DECLARE @cond INT;
SET @cond = 1
END TRY
BEGIN CATCH
PRINT 'a'
END CATCH;
COMMIT TRAN TranA

This first transaction runs without a problem


Now change value of @cond from 1 to 'A' and run this code below.
BEGIN TRANSACTION TranA
BEGIN TRY
DECLARE @cond INT;
SET @cond = 'A';
END TRY
BEGIN CATCH
PRINT 'a'
END CATCH;
COMMIT TRAN TranA



This transaction will blow up with the following message
Server: Msg 3930, Level 16, State 1, Line 15
The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.
Server: Msg 3998, Level 16, State 1, Line 1
Uncommittable transaction is detected at the end of the batch. The transaction is rolled back.


We can use XACT_STATE() to check if we need to rollback or not without blowing up. I also used the ERROR_MESSAGE() function to print the error

BEGIN TRANSACTION TranA
BEGIN TRY
DECLARE @cond INT;
SET @cond = 'A';
END TRY
BEGIN CATCH
PRINT ERROR_MESSAGE();
END CATCH;
IF XACT_STATE() =0
BEGIN
COMMIT TRAN TranA
END
ELSE
BEGIN
ROLLBACK TRAN TranA
END

After running that we can see that the following message was printed

Conversion failed when converting the varchar value 'A' to data type int.

We trapped the error, rolled back the transaction and the transaction did not blow up

EXISTS or COUNT(*)

Do you use this

IF (SELECT COUNT(*) FROM SomeTable
WHERE SomeColumn = SomeValue ) > 0

Or do you use this

IF EXISTS (SELECT * FROM SomeTable WHERE SomeColumn = SomeValue )

If you answered COUNT(*) then maybe you should take a look these two articles

The Strange Case OF Nulls And Case

Okay it is not Dr. Jekyll and Mr. Hyde but I had to come up with a title. This was a question someone asked yesterday in the sql programming group


http://groups.google.com/group/microsoft.public.sqlserver.programming/browse_thread/thread/126735827b7ae667#

This person had a case statement like this

SELECT
CASE
WHEN COL1 IS NULL THEN 'UNK'
WHEN COL1 = 'SUGAR' THEN 'SGR'
WHEN COL1 = 'SALT' THEN 'SAL'
WHEN COL1 = 'PEPPER' THEN 'PEP'
END AS items
FROM #INV_ITEMS

This still returned NULLS. Can you spot the flaw? there is no else statement, if there is a value which is not sugar, salt or pepper then a NULL will be returned. let's take a look.

Create this table

CREATE TABLE #INV_ITEMS (COL1 varchar(23))
INSERT #INV_ITEMS VALUES('SUGAR')
INSERT #INV_ITEMS VALUES('SALT')
INSERT #INV_ITEMS VALUES('PEPPER')
INSERT #INV_ITEMS VALUES('WASABI')

Now run this
SELECT
CASE
WHEN COL1 IS NULL THEN 'UNK'
WHEN COL1 = 'SUGAR' THEN 'SGR'
WHEN COL1 = 'SALT' THEN 'SAL'
WHEN COL1 = 'PEPPER' THEN 'PEP'
END AS items
FROM #INV_ITEMS

Output
--------
SGR
SAL
PEP
NULL


So we get a NULL, but which row is that? We just add the column to find out


SELECT Col1,
CASE
WHEN COL1 IS NULL THEN 'UNK'
WHEN COL1 = 'SUGAR' THEN 'SGR'
WHEN COL1 = 'SALT' THEN 'SAL'
WHEN COL1 = 'PEPPER' THEN 'PEP'
END AS items
FROM #INV_ITEMS


Output
--------
SUGAR SGR
SALT SAL
PEPPER PEP
WASABI NULL

Aha, it is the wasabi.

Let's try again by including an ELSE


SELECT Col1,
CASE
WHEN COL1 IS NULL THEN 'UNK'
WHEN COL1 = 'SUGAR' THEN 'SGR'
WHEN COL1 = 'SALT' THEN 'SAL'
WHEN COL1 = 'PEPPER' THEN 'PEP'
ELSE 'UNK'
END AS items
FROM #INV_ITEMS

Output
--------
SUGAR SGR
SALT SAL
PEPPER PEP
WASABI UNK

There we go, it is correct now.

Now let's make it more interesting by inserting a blank, a space and a NULL


INSERT #INV_ITEMS VALUES('')
INSERT #INV_ITEMS VALUES(' ')
INSERT #INV_ITEMS VALUES(NULL)

We can use a combination of NULLIF and RTRIM to filter out blanks, spaces and NULLS

SELECT Col1,
CASE
WHEN NULLIF(RTRIM(COL1),'') IS NULL THEN 'NullOrBlank'
WHEN COL1 = 'SUGAR' THEN 'SGR'
WHEN COL1 = 'SALT' THEN 'SAL'
WHEN COL1 = 'PEPPER' THEN 'PEP'
ELSE 'UNK'
END AS items
FROM #INV_ITEMS

Output
--------
SUGAR SGR
SALT SAL
PEPPER PEP
WASABI UNK
NullOrBlank
NullOrBlank
NULL NullOrBlank

And there it is

DROP TABLE #INV_ITEMS

Screencast: SQL Server 2008 - Table valued parameters

If you have to insert more than one row of data in a Table, you end up executing the insert statement / stored procedure as many times for each row, with Table-valued parameters you can send multiple rows of data to a single TSQL statement or stored procedure without creating temp tables or doing multiple round trips.

Table-valued parameters are a new parameter type in SQL Server 2008 and are declared by using user-defined table types.

Integer Math In SQL Server

What do you think the following query will return in SQL Server?

SELECT 3/2

If you said 1.5 then you are wrong! The correct answer is 1, this is because when doing division with 2 integers the result will also be an integer.
There are two things you can do
1 multiply one of the integers by 1.0
2 convert one of the integers to a decimal


Integer math is integer result
DECLARE @Val1 INT,@val2 INT
SELECT @Val1 =3, @val2 =2

SELECT @Val1/@Val2

Result 1

Convert explicit or implicit to get the correct answer
DECLARE @Val1 INT,@val2 INT
SELECT @Val1 =3, @val2 =2

--Implicit
SELECT @Val1/(@Val2*1.0)
--Explicit
SELECT CONVERT(DECIMAL(18,4),@Val1)/@Val2

Result 1.50000000000000

Visual Studio 2005 Support for SQL Server 2008, Community Technology Preview

This CTP resolves a problem that when you try to open a database connection to SQL Server 2008 by using Visual Studio 2005 design tools, you may receive the following error message:
“This server version is not supported. Only servers up to Microsoft SQL Server 2005 are supported.”
This CTP addresses this issue, and enables the following Visual Studio functionality for SQL Server 2008 CTP5 :

• Server Explorer successfully connects to SQL Server 2008, and database objects such as stored procedures and table data can be viewed and edited. Note that table schemas still cannot be viewed or edited in this release.
  
• SQL CLR projects that target SQL Server 2008 CTP5 can be created and deployed to the server.
  
• T-SQL and SQL CLR debugging are now enabled for SQL Server 2008 CTP5.
  Data binding features in Client and Web Projects are enabled.

This CTP does not support the following features for SQL Server 2008 Nov CTP:

• Creating and editing table schemas in Table Designer or Database Diagrams. The table designer feature in SQL Server Management Studio 2008 can be used to edit table schemas in SQL Server 2008 CTP5.
