SQL Sentry’s Plan Explorer PRO – Now Completely Free

Wow, that’s very impressive – and a huge win for SQL Server Professionals everywhere.


SQL Sentry just announced that the PRO version of Plan Explorer is now completely free – as in you don’t even have to register to use it. (For those in the know, there used to be two versions: a ‘lighter-weight’ free version, and a paid-for PRO version; they’ve now consolidated all features into the PRO version – and made it free.)

Spoil Yourself with Better Insight and Analysis

I’ll be honest: since I spend so much of my time on my clients’ machines when analyzing performance problems and looking at execution plans, I’ve made a conscious effort in the past to avoid using Plan Explorer too much in my Lab – for fear of spoiling myself.

This announcement changes all of that – meaning that I’ll have a whole suite of additional tools at my disposal when performance tuning or troubleshooting.

SQL Sentry’s Motivation

It doesn’t take a genius to see that SQL Sentry is trying to use Plan Explorer PRO to establish a ‘foot in the door’ with as many potential customers and clients as possible.

But a maneuver like this only works with a market when you’re providing something that users REALLY want, management can easily see the value being offered, and the tool being offered is really solid (non-buggy).

Interestingly enough, that sums up Plan Explorer PRO perfectly.

One of My Favorite Undocumented T-SQL Snippets

While there are tons of undocumented T-SQL commands out there, one of my all-time favorites is this little gem:


It’s not much, but it will show you default details on:


 Arguably, there are better ways to retrieve some of this information (like SELECT * FROM sys.dm_server_registry;).

But SERVERPROPERTY(‘ErrorLogFileName’) works just fine when looking for low-level details.

The only real problem I have with this particular snippet of T-SQL is that I can never remember EXACTLY what the property is to ‘search’ for (i.e., ‘ErrorLogFileName’) – which is part of why I’ve blogged about it (so that I’ll be able to more easily find this snippet in the future).
