Thanks SQLMenace (Denis Gobo) for this great tip on getting min/max/average row sizes (and more) using DBCC SHOWCONTIG.
Don’t forget the “with tableresults”, without it, it will skip the min/max/average recordsize from the results, and present the results as text (not as a row).
Run DBCC SHOWCONTIG with your table name
dbcc showcontig ('TableName') with tableresults
then look at max min and average record size
This feature works at least from SQL Server 2000 onward, though somewhere after SQL Server 2012 it will be removed.
As of SQL Server 2005 you can use sys.dm_db_index_physical_stats. An example on how to use that is here.
It just made me shiver when finding out an unindexed table with 9 million rows averaging about 300 bytes took 8 minutes to query.
Time to add some indexes, and have someone look at the disk back-end.

Being used to do Unit Testing in most of my regular code, I want to do the same for SQL Server code.
Target is SQL Server 2000 and up (since I’m involved in a big migration project getting a lot of SQL Server 2000 data and code to be upgraded to SQL Server 2012 or SQL Server 2008 R2).
Here are a few links that are on my research list:

Never call this encryption, as ROT13 is just a kind of obfuscation for text and can be easily revealed (like the reveal button in good old Teletext).
A few T-SQL versions of this algorithm, both working for SQL Server 2000 and up:

As a follow-up on my earlier number validation posts (Elf proef in C# and Other number verifications), I found a nice T-SQL version of the Elfproef for Dutch bank account numbers.
It works at least from SQL Server 2000 and up, most likely also in the (unsupported) SQL Server 7.

Few people know about the INFORMATION_SCHEMA views that have been there since SQL-92.
Two funny things about that standard:
A few reasons I can imagine not many people know about the INFORMATION_SCHEMA:
- Not all relational database servers implement them, and of the ones that do implement them, not all versions implement all views.
That’s what this article is about; currently it lists only SQL Server 2000 and 2008 R2 (tried both) and PostgreSQL (verified docs), but I will update it as soon as I have run the script on other versions of SQL server and database vendors.
- It is hard to find the official ISO standards in a public way, and ISO itself sometimes puts things online, and at other times wants money for it
I remember the Y2K preparation era where the ISO-8601 standard was freely available at http://www.iso.ch/markete/8601.pdf, soon after the Year 2000, the PDF got locked behind a payment engine.
ISO suffers from heavy link rot too, for instance the ISO 3166 country codes used to be at http://www.iso.org/iso/prods-services/iso3166ma, but are now at http://www.iso.org/iso/home/standards/country_codes.htm. What about HTTP 303 or 302 redirect here guys?
Since SQL-92, the INFORMATION_SCHEMA (and its twin DEFINITION_SCHEMA) have been extended. The last extension in 2008. Together they allow SQL databases to be self-describing (I think no vendor has attained that) and the structures queryable in a standard way
In fact that is the main purpose: these views in INFORMATION_SCHEMA are a very convenient standard way to query – in a vendor agnostic way – about tables, views, columns, etc. Read the rest of this entry »

A few weeks ago, Bill Karwin did a must watch webinar on the prevention SQL Injection titled “SQL Injection Myths and Fallacies“.
Bill Karwin (twitter, new blog, old blog, Amazon) is famous for much work in the SQL database community, including InterBase/Firebird, mySQL, Oracle and many more.
He also:
Anyway, his webinar is awesome. Be sure to get the slides, watch the replay, and read the questions follow up.
Watching it you’ll get a better understanding of defending against SQL injection.
A few very valuable points he made: Read the rest of this entry »

Close to 5 months after SQL Server 2012 got released to manufacturing, SQL Server 2008 R2 Service Pack 2 became available last week (July 26th, 2012).

Yes. Dorothy. There are people using the ADO .NET Entity Framework with SQL Server 2000 in parallel of moving towards a more modern Microsoft SQL Server version.
Entity Framework is lovely for developing data-centric applications.
By default, Visual Studio 2010 will target SQL Server 2008 as a database. That is fine, but it is kind of invisible it does: there is no property or dialog where you can change this.
What you have to change in order to have the Entity Framework send SQL Server 2000 compatible queries is to:
- Right click your .edmx file
- Choose “Open with”
- Choose the “XML (text) editor”
- Find the ProviderManifestToken attribute
- Change the value (usually from “2008”) into “2000”
- Save the .edmx file
- Build and run your application
A few caveats:

When in a DTAP environment, you cannot always have complete clean boundaries. Issues in production don’t reproduce in acceptance, you cannot develop in production, etc.
So sometimes you have to simulate or connect to Test or Acceptance Database Servers from a Develop workstation.
There it can get hairy to keep track of which applications connect to which database server.
That’s where the below batch file comes in handy: it scans your systems on connections to common TCP ports used by SQL server, then for each connection give you some process details (or – if you add a commandline parameter – all details that TLINK can get).
The batch file uses the built in tools tasklist, netstat, find and sc (the latter to show information on the local running SQL Services).
It also uses TLIST, which can be a bit awkward to get.
