ExpressProfiler now is digitally signed.

Today I've replaced download package for ExpressProfiler with digitally signed version of standalone application and Ecosystem installation.
Unfortunately I did something wrong and reset download statistics to zero :( Hope that Codeplex's guys can help.
However this is not a big deal - ExpressProfiler looks popular and can reach big download numbers in a just few days :)

Complexity. How it is calculated.

What are the magic pink numbers you can see in Code Outline window?Code Outline complexity numbers
The answer is very simple - these are Code Complexity numbers. Each number represents complexity of outlined node, something like Cost in query execution plan. The same numbers you can see after Complexity check - but for whole procedure, not for each statement.
So how Complexity is calculated?

Varchar "miracle" and best practice

I've just spent fifteen minutes helping colleague to find "miracle in t-sql code".
- There should be rows, definitely! I can run simple query and voila! 4 thousands of rows selected! So why there are no rows when I'm doing a simple left join with small filter expression?
There is no miracle of course.

ExpressProfiler: The New Kid on the Block

I'm pleased to inform you that yet another of my pet-projects, ExpressProfiler, joined the rapidly growing family of Ecosystem-based tools for SQL Server.
You may ask me, "why should I use ExpressProfiler if there is standard profiler supplied with SQL Server?"
There are a number of reasons:
First - not every edition of SQL Server has a profiler. The Express edition didn’t benefit from a profiler until 2012SP1.
Of course you can buy the inexpensive Developer Edition, but what will you do on environments where only SQLExpress is installed? Will you install The Developer Edition? Of course not. The solution is to download ExpressProfiler, which doesn't need to be installed. Simply copy a single executable and run it! (it also comes with an optional installer.)
Okay. You may say, "I already have the Standard (or even Enterprise) edition of SQL Server. Why do I need ExpresProfiler?"
1. It is small and simple.
2. It is always ready for action (especially when launched from SSMS, which supplies it with your server connection settings)
3. It is fast. I'm not joking. When you are working in a remote session with servers in your datacenter, ExpressProfiler is much faster than the standard profiler due to its far simpler UI.

Psst! Wanna some API?

If you have already visited SQL Code Guard's website you might notice a reference to an "API for custom tool development". Pretty cool sounding, isn’t it? SQL Code Guard can not only find issues as a standalone tool, but also exposes its capabilities to be used in your own solutions!

A few words about simplicity: Using Red-Gate Ecosystem framework

In my first blog post I briefly covered when and why I created SQL Code Guard (SCG).
To be honest, the first version of SCG was a standalone application, but supporting a GUI took too much time so I decided to convert it to an SSMS plugin – in this case I was able to use SSMS’s GUI, its editors, syntax highlighting and so on.

After  some considerable research I discovered that the knowledge on how to write an SSMS addin is a much hidden treasure.
