SQL Server Collation

Question: I was putting together a small bit of SQL code the other day, and I was running into a bug. While debugging it, I was completely shocked to discover:

IF 'a' < 'A'
SELECT 'a < A'

IF 'a' = 'A'
SELECT 'a = A'

IF 'a' > 'A'
SELECT 'a > A'

IF 'a' <> 'A'
SELECT 'a <> A'

displays only 'a = A'.

I investigated and found out that the reason for this result is that the database's collation sequence is set to one of the "CI" values (Case Insensitive). I took a look at a couple of other databases, and they were also "CI". Oddly enough, they were slightly different collation sequence values, but definitely "CI". This includes the [master] database.

Yes, I know it could have been configured the other way. That's not the point of this note. Is "CI" the expected standard configuration?

In addition to the crazy logic implications, I've got to believe that it's at least a bit slower to execute, since all text-based columns needs to be compared in a case-insensitive way. That character set translation can't come for free.


Answer:
The collation setting is specified during the installation of SQL Server. As seen in Figure 1, the default settings used during the installation of SQL Server 2012 are:

Database Engine: SQL_Latin1_General_CP1_CI_AS
Analysis Services: Latin1_General_CI_AS


Figure 1: SQL Server 2012 Default Collation Settings

Technically, there is no "expected CI standard". It all depends on the collation setting of the database. This is not to say you're stuck with that setting forever. If you visit http://msdn.microsoft.com/en-us/library/ms143726.aspx, you will see the following excerpt:

Setting collations are supported at the following levels of an instance of SQL Server:
Server-level collations
The default server collation is set during SQL Server setup, and also becomes the default collation of the system databases and all user databases. Note that Unicode-only collations cannot be selected during SQL Server setup because they are not supported as server-level collations. After a collation has been assigned to the server, you cannot change the collation except by exporting all database objects and data, rebuilding the master database, and importing all database objects and data. Instead of changing the default collation of an instance of SQL Server, you can specify the desired collation at the time that you create a new database or database column.

Database-level collations
When a database is created or modified, you can use the COLLATE clause of the CREATE DATABASE or ALTER DATABASE statement to specify the default database collation. If no collation is specified, the database is assigned the server collation.
You cannot change the collation of system databases except by changing the collation for the server. The database collation is used for all metadata in the database, and is the default for all string columns, temporary objects, variable names, and any other strings used in the database. When you change the collation of a user database, know that there is the potential for collation conflicts when queries in the database access temporary tables. Temporary tables are always stored in the tempdb system database, which will use the collation for the instance. Queries that compare character data between the user database and tempdb may fail if the collations cause a conflict in evaluating the character data. You can resolve this by specifying the COLLATE clause in the query. For more information, see COLLATE (Transact-SQL).

Column-level collations
When you create or alter a table, you can specify collations for each character-string column by using the COLLATE clause. If no collation is specified, the column is assigned the default collation of the database.

Expression-level collations
Expression-level collations are set when a statement is run, and they affect the way a result set is returned. This enables ORDER BY sort results to be locale-specific. Use a COLLATE clause such as the following to implement expression-level collations:

SELECT name FROM customer ORDER BY name COLLATE Latin1_General_CS_AI;

For more information on changing collation, please visit http://msdn.microsoft.com/en-us/library/ms179254.aspx.

Using the "Shrink Volume" Utility

 One of the best kept secrets of Windows 7 is the "Shrink Volume" utility. TechNet Documentation explains it best at http://technet.microsoft.com/en-us/magazine/gg309169.aspx. Although, this link explains how to use it, it does not list all the advantages of using it.  That will be my goal for this article.

The utility will shrink the current volume, leaving all files intact, without a problem.  Although I used this utility many times in the past without issue, I still highly recommend performing a full back-up before using it.  After all, a good backup is always the best insurance against any unforeseen issue.

This free utility allows you to shrink a large volume on your hard drive that is not fully utilized.  For example, most developers have large hard drives.  In most cases, they probably have more than 100GB of unused space.  In addition, they most likely have a need to install additional OS for trial or multi-use purposes.  By using the Shrink Volume utility, you can now leverage unused space on your hard drive and install different OS’s.

For example, I have a machine with a 500GB Hard drive and only 1 partition (C :\).  This partition has Windows 7 installed on it.  With all my other storage on it, I was using about 300GB with the remaining 200GB unused.  I needed to install SharePoint and SQL Server for a new client but wanted to keep it separate from work I was doing for other clients.  SharePoint 2010 requires 64-Bit hardware so I could not run it in a Virtual PC machine.  I tried using Hyper-V but ran into several problems.

I used the Shrink Volume utility (as outlined in the TechNet documentation) to reduce my C: drive by 50GB, thus creating a new 50GB partition.  I used the new partition to install Windows 2008, SharePoint 2010, and SQL Server. A few months later, I needed to install Windows 8 so I did the same thing and extracted another 41 GB from C: by shrinking it.  Now I have three operating systems installed on my hard drive, each fully utilizing the 64-bit capability of my PC and all of its hardware components without any virtualization.

Boot Manager
After following the directions listed on the TechNet link above, I simply rebooted my PC with a DVD of the new OS inserted in the DVD player.  When prompted by the installer, I chose the new empty partition I recently created.  The installer then formatted it, installed the new OS, and setup the Boot Manager with all the existing OS’s.
After installation was completed, the PC rebooted once more.  After the system check, I was prompted to select an OS from the Boot Manager Menu within a specified number of seconds. 
 

Boot Manager Settings
The settings for the Boot Manager can be changed from two places. First, it can be accessed from the Control Panel > System > Change settings > “Advanced” tab > “Settings” in Startup and Recovery section.
The second method allows for more advanced options of the Boot Manager.  It can be accessed from Control Panel > Administrative Tools > System Configuration > “Boot” tab.

Partition Access
Once you select the operating system of choice, the PC will boot normally.  The partition with the chosen operating system will become “C:\” and the other partitions will be assigned other drive letters.  This happens automatically without user intervention.  The other partitions will be exposed and the files on them will be accessible. This allows access to the file system on each partition without having to boot into that specific partition. 

Summary
In closing, listed below are all key advantages of using the Shrink Volume utility.
• Free built in utility: The Shrink Volume utility is standard on all Windows 7 machines, as part of the OS.
• Reliable: All files are left in place without corruption.  However, a full backup is highly recommended before using this utility.
• Automatically configures Boot Manager menu
• All partitions are always visible and accessible
• Leverages your current investment in hardware by using free disk space
• New OS’s are installed natively on the machine, accessing all hardware without virtualization.
