How To Make A FileGroup Read Only in SQL Server 2005

How to make a filegroup read only in SQL Server 2005? This question popped up today on tek-tips. This is how you do that: First we will create a new database named TestFilegroup. Next we will add a filegroup named Test1FG1 which contains a file named test1dat3.
The next step is to do an alter database modift filegroup readonly command
Here is the complete script

USE master
go

--Create New DB For Testing
CREATE DATABASE TestFilegroup
go


--Create FileGroup
ALTER DATABASE TestFilegroup
ADD FILEGROUP Test1FG1;

--Add file to fileGroup
ALTER DATABASE TestFilegroup
ADD FILE
(
NAME = test1dat3,
FILENAME = 'c:\t1dat3.ndf',
SIZE = 5MB,
MAXSIZE = 100MB,
FILEGROWTH = 5MB

)
TO FILEGROUP Test1FG1

--Make FileGroup ReadOnly
ALTER DATABASE TestFilegroup
MODIFY FILEGROUP Test1FG1 Read_Only;

Use Read_Only not ReadOnly because the keyword READONLY will be removed in a future version of Microsoft SQL Server. Avoid using READONLY in new development work, and plan to modify applications that currently use READONLY. Use READ_ONLY instead.




Now what happens when you try to create a table on filegroup Test1FG1?
USE TestFilegroup
GO
CREATE TABLE abc (id INT) ON Test1FG1

You will see the following error message
Server: Msg 1924, Level 16, State 2, Line 1
Filegroup 'Test1FG1' is read-only.

You can use sys.filegroups and check the is_read_only column to find out if a filegroup is read only
SELECT is_read_only
FROM sys.filegroups
WHERE name = 'Test1FG1'

Here is the result
is_read_only
------------

Using NTFS Compression with Read-Only User-defined Filegroups and Read-Only Databases
SQL Server 2005 supports NTFS compression of read-only user-defined filegroups and read-only databases. You should consider compressing read-only data in the following situations:
You have a large volume of static or historical data that must be available for limited read-only access.
You have limited disk space.

Visual Studio Code Name "Orcas" - March 2007 Community Technology Preview (CTP) Available For Download

Get it here and start messing around with LINQ:

http://www.microsoft.com/downloads/details.aspx?FamilyID=b533619a-0008-4dd6-9ed1-47d482683c78&DisplayLang=en

From the site:

Visual Studio code name “Orcas” delivers on Microsoft’s
vision of smart client applications by enabling developers to rapidly create
connected applications that deliver the highest quality rich user experiences.
This new version enables any size organization to rapidly create more secure,
manageable, and more reliable applications that take advantage of Windows Vista
and the 2007 Office System. By building these new types of applications,
organizations will find it easier than ever before to capture and analyze information
so that they can make effective business decisions.



This download is the March 2007 Community Technology Preview of Microsoft
Visual Studio Code-Named “Orcas”. This CTP is available in English only.



Note: 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.



This CTP targets early adopters of the Microsoft technology, platform, and
tools offerings. It enables developers to experience the upcoming toolset and
underlying platform improvements. We designed this release to enable developers
to try out new technology and product changes, but not to build production
systems. This limitation is fully covered in the EULA that accompanies this
CTP.



The highlights of this CTP include:

• LINQ
  
  The LINQ Project: this CTP represents a major milestone in the LINQ
  project. For more information about LINQ click here.
  
• VB 9.0 Language
  Support: This CTP contains the following language features:
• Query Expressions:
  Basic querying, filtering, and ordering support
• Object Initializers
• Extension Methods
• Local Variable Type
  Inference
• Anonymous Types
• XML literals
• XML properties
• New Line and
  Expression IntelliSense
• 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
• Complete design-time
  support: Intellisense, Formatting, Colorization
• LINQ to ADO.NET
• 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.
• LINQ to Entities
  enables developers to program against a relational database using a view
  of the data that is appropriate for the application they are building,
  independent of the structure of 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. LINQ to Entities is built
  on the ADO.NET Provider model and will support working against different
  back end relational stores in addition to Microsoft SQL Server. This CTP
  includes a LINQ to Entities provider for SQL Server and SQL Server
  Compact Edition.
• LINQ to SQL (previous
  name DLinq) has enhanced the functionality from the May 2006 LINQ CTP.
  You can find it in System.Data.Linq namespace in System.Data.Linq.dll.
  New in this release is that DataContext provides optimized modes for
  read-only use and serialization . Also new is that DataShape streamlines
  eager loading capabilities and adds the ability to set queries on
  relationships
• LINQ To SQL Designer
• Methods can be created
  from stored procedures and functions within the designer.
• Better handling of
  database schemas.
• Improved inheritance
  support in the designer.
• LINQ over XML (XLinq)
• System.Xml Bridge
  Classes added – There is a set of extension methods allowing XPath /
  XSLT to be used over LINQ to XML trees, allow XSLT transformations to
  produce an LINQ to XML tree, and to validate an XElement tree against an
  XML Schema.
• Event Model - This
  allows LINQ to XML trees to be efficiently synchronized with a GUI, e.g.
  a Windows Presentation Foundation application
• Class hierarchy
  changes - XObject class added, XStreamingElement class (temporarily)
  removed
• Various
  understandability / usability improvements – There have been a number of
  relatively minor changes done in response to internal reviews, usability
  studies, and external feedback to make the API more clean and
  consistent.
• 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.

• ADO.NET
• Extended, more powerful
  data APIs with the ADO.NET Entity Framework
• 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.
• Added paging and stored
  procedures for update (“update customization”) for ADO.NET Entity
  Framework:
• Paging: the paging
  support in the ADO.NET Entity Framework allows developers to “page” over
  data in a database by indicating the start row and number of rows to be
  included in the result. Paging is available through Entity SQL (using
  the LIMIT AND SKIP keywords) and through the query-builder methods in
  the ObjectQuery &ltT> class (Top and Skip). In a future CTP the
  feature will also be enabled to be used in LINQ queries by means of the
  standard Take and Skip LINQ operators.
• Stored-procedures for
  update customization: the Entity Framework by default automatically
  generates SQL statements for insert, update and delete operations when
  processing changes to entities in memory to be sent to the database.
  With the stored-procedures update customization feature developers have
  the option to override the automatic SQL generation and instead provide
  stored-procedures that will perform the insert, update and delete
  operations, which the system will call during entity change processing.
  Among other things, this enables scenarios where direct access to tables
  is restricted in the database and the only way to make changes to the
  data is through stored-procedures.
• Microsoft
  Synchronization Services for ADO.NET
• Provides an
  application programming interface (API) to synchronize data between data
  services and a local store. The Synchronization Services API is modeled
  after the ADO.NET data access APIs and gives you an intuitive way to
  synchronize data. It makes building applications for occasionally
  connected environments a logical extension of building applications
  where you can depend on a consistent network connection. For details
  please visit http://go.microsoft.com/fwlink/?LinkId=80742

  – There are many components to this, including build queuing and queue management,
  drop management (so that users can set policies for when builds should
  be automatically deleted), and build triggers that allows configuration
  of exactly how when CI builds should be triggered, for example – every
  checkin, rolling build (completion of one build starts the next), etc.
• Improved ability to
  specify what source, versions of source, etc to include in a build.
• Improved ability to
  manage multiple build machines.
• Simplified ability to
  specify what tests get run as part of a build
• Version Control support

  files and folders cannot be recovered once they are destroyed. Destroy
  allows administrators to achieve SQL server disk space usage goals
  without constantly needing to add more disks to the data tier machine.
  Destroy also facilitates removing versioned file contents that must be
  permanently removed from the system for any other reason.
• Annotate - Annotate is
  a feature that allows developers to inspect a source code file and see
  at line-by-line level of detail who last changed each section of code.
  It brings together changeset data with difference technology to enable
  developers to quickly learn change history inside a source file.
• Folder Diff - Team
  Foundation Server now supports compare operations on folders, whereby
  the contents of the folder are recursively compared to identify files
  that differ. Folder diff can compare local folders to local folders,
  local folders to server folders, and server folders to server folders.
  It’s a great way of identifying differences between branches, files that
  you’ve changed locally, and files that have changed between two points
  in time.
• Get Latest on Checkout
  - As an optional setting on a team project or on an individual basis,
  you can have Team Foundation Server always download the latest version
  of a file when you check it out. This helps ensure that you don’t have
  to merge your changes with somebody else’s when you check the file back
  in.
• Performance and Scale
• This release includes
  numerous improvements in performance and scalability of Team Foundation
  Server.

• Visual C++
• Easily add the Windows
  Vista “Look and Feel” to native C++ applications
• Developers can use
  Visual Studio to build ISV applications that exhibit the Windows Vista
  “look & feel”. A number of the Windows Vista “look & feel”
  features are available simply by recompiling an MFC application. Deeper
  integration that requires more coding or design work on the part of the
  developer is also simplified with Visual Studio’s integrated support for
  the Windows Vista native APIs.

Existing CTPs: As Visual Studio code name “Orcas” CTPs are released on a predefined cadence, existing CTPs (such as the LINQ May 2006 CTP) may not yet have been integrated into a given “Orcas” CTP release (This should not be taken as a change in commitment to any existing technology that has been made available as a CTP but instead is just a real world example of how large applications, with many technology areas, are built. We will be integrating this existing functionality into future CTP builds.

Developers using a VPC image can run the CTP on a machine without impacting any existing software installations. The CTP can be removed by deleting the folder and using the Virtual PC application to remove the configuration information.

This image ships with networking set to “local”. This setting enables the virtual machine to think it is connected to a network without actually connecting and exposing the machine to the Internet. We recommend that customers do not modify the networking settings. Customers who wish to turn networking “on” to connect the image to a physical network are advised that they will need to ensure the security of the virtual machine as well as apply any security updates that may have become available since the release of this image.

Using ALTER INDEX…REBUILD To Rebuild A Clustered Index Does Not Rebuild Its Nonclustered Indexes By Default On SQL Server 2005

How many times have you asked/been asked the following question: Does rebuilding a clustered index rebuild nonclustered indexes?

Well Ken Henderson has the answer for you on his blog.

On SQL Server 2005, using ALTER INDEX…REBUILD to rebuild a clustered index
does not rebuild its nonclustered indexes by default

Failure Trends in a Large Disk Drive Population

The Google engineers published a paper on Failure Trends in a Large Disk Drive Population. Based on a study of 100,000 disk drives over 5 years they found some interesting stuff:

While drive manufacturers often quote yearly failure rates below 2%,
user studies have seen rates as high as 6%.

We find, for example, that after their first scan error, drives are 39
times more likely to fail within 60 days than drives with no such errors. First
errors in reallocations,offline reallocations, and probational counts are also
strongly correlated to higher failure probabilities.

Six percent, that is higher than I expected. I must say (and I am knocking on wood as I write this) that I only saw a drive die once (within a month of deploying) on a blade server. The only major problem I had was when consulting for a client in NYC. They had a SQL Server box which was running for 2 years without a problem. We upgraded the machine to an active/passive cluster and a week later the motherboard died (downtime 20 seconds ;-) ), talking about good timing.....

So what failure rates do you see? Does stuff break down a lot?

How To Find Out Which Columns Have Defaults And What Those Default Values Are

Okay so many many moons ago you created a bunch of tables and those tables have columns of course. You want to know how to find the columns that have defaults.
There are a couple of ways to do this
Below is a list:

1 INFORMATION_SCHEMA.COLUMNS view (2000 and 2005)
2 sysobjects,syscolumns and syscomments (2000 only)
3 sys.default_constraints and sys.sysobjects (2005 only)
4 sp_help (2000 only)


So let's get started with some code
CREATE TABLE blah(id INT DEFAULT 0,
SomeDate DATETIME DEFAULT CURRENT_TIMESTAMP)

INSERT blah DEFAULT VALUES

SELECT * FROM blah


--SQL 2000/2005
SELECT COLUMN_DEFAULT,*
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME ='blah'

--SQL 2000
SELECT Text,*
FROM sysobjects o
INNER JOIN syscolumns c
ON o.parent_obj = c.id
AND o.info = c.colid
INNER JOIN syscomments s
ON o.id = s.id
WHERE o.xtype = 'D'
AND OBJECT_NAME(parent_obj) = 'blah'

--SQL 2005
SELECT * FROM
sys.default_constraints d
JOIN sys.sysobjects o ON d.parent_object_id = o.id
WHERE o.name = 'blah'


See what happens when you don't specify a name (we will do this later)? You will get wacky names like these: DF__blah__id__15A53433 and DF__blah__SomeDate__1699586C
Instead of specifying the default when creating the table use an alter table add constraint statement.Let's see this in action.

DROP TABLE blah
CREATE TABLE blah(id INT,SomeDate DATETIME)

ALTER TABLE blah
ADD CONSTRAINT DF_Blah_ID_0
DEFAULT 0 FOR id

ALTER TABLE blah
ADD CONSTRAINT DF_Blah_SomeDate_Now
DEFAULT CURRENT_TIMESTAMP FOR SomeDate


INSERT blah DEFAULT VALUES

SELECT * FROM blah


--SQL 2000/2005
SELECT COLUMN_DEFAULT,*
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME ='blah'

--SQL 2000
SELECT Text,*
FROM sysobjects o
INNER JOIN syscolumns c
ON o.parent_obj = c.id
AND o.info = c.colid
INNER JOIN syscomments s
ON o.id = s.id
WHERE o.xtype = 'D'
AND OBJECT_NAME(parent_obj) = 'blah'

--SQL 2005
SELECT * FROM
sys.default_constraints d
JOIN sys.sysobjects o ON d.parent_object_id = o.id
WHERE o.name = 'blah'

And last we have sp_help
You can use sp_help in SQL Server 2000(you can also use it in SQL server 2005 but it doesn't return the defaults )
Execute the following
sp_help 'blah'

The defaults will be in the last resultset (the one where the first column name = constraint_type)


And last but not least did you notice that we had CURRENT_TIMESTAMP but when we queried the table we saw GETDATE() This is kind of strange since CURRENT_TIMESTAMP is ANSI complaint but GETDATE() is not

Podcast With Dr. Peter Chen on the Entity Relationship Model and ADO.NET Entity Framework On Channel 9

If you are a SQL developer then you have probably heard of Dr. Peter Chen, he is the person who wrote the original paper on Entity-Relationship model (ER model).


From the site:
Dr. Peter Chen is a Fellow of ACM, IEEE, and AAAS and has received many prestigious awards including ACM/AAAI Allen Newell Award and IEEE Harry Goode Award. He has been listed in Who’s Who in America and Who’s Who in the World for more than 15 years.

Dr. Chen's original paper on the
Entity-Relationship model (ER model), published in 1976 is one of
the most cited papers in the computer software field. Based on one particular
citation database, Chen's paper is the 35th most cited
article in Computer Science. It is the 4th most downloaded
paper from the ACM Digital Library in January 2005 (Communications of ACM, March
2005) even though the paper was published 30 years ago.

Dr. Chen’s work is a cornerstone of software engineering, in particular Computer-Aided Software Engineering (CASE). In the late 80’s and early 90’s, IBM’s Application Development Cycle (AD/Cycle) framework and DB2 repository (RM/MVS) were based on the ER model. Other vendors’ repository systems such as Digital’s CDD+ were also based on the ER model. Prof. Chen has made significant impact on the CASE industry by his research work and by his lecturing around the world on structured system development methodologies. Most of the major CASE tools including Computer Associates’ ERWIN, Oracle’s Designer/2000, and Sybase’s PowerDesigner (and even a general drawing tool like Microsoft’s VISIO) are influenced by the ER model.


In this podcast, Brian Beckman interviews Dr. Chen along with Jose Blakeley, Software Architect, SQL Server, and Britt Johnston, Director of Program Management, Data Programmability
