Like thousands of developers, I eagerly downloaded SQL
Server 2005 Express Edition mere moments after receiving an e-mail from Microsoft.
Unfortunately, after installing it on my development box, I realized that I had
a mess on my hands. Hopefully, by sharing my experience with SQL Express, I may
shed some light on what other developers might be going through with this
installation. (Note: This article is not
a panacea. I have yet to figure out the myriad of things that went wrong with
my installation. I suggest that you take every possible care to recover from your

installation is Custom, since I do not like to place programs and data
upon the same drive. I have several drives, but the case in point uses c:\
as the programs drive and f:\ as the data drive. (It’s an old habit
acquired from the days of DOS—programs on one drive, data on another.)

a dozen databases) and the new stuff.

2000 is running successfully! But to guarantee the safety of my existing
databases, I choose a new directory as the base data directory.
copy several MDF files from the previous directory to the new directory,
and then I run “sp_attach_single_file_db”
against each one in succession. (If you don’t know what this means, open
BOL and search for that procedure name.)

databases and I was back in business.

Everything is once again intact, and SQL Express has her own sandbox in

My suggestions for installing SQL Express
This was not fun. If you plan on installing SQL Express
betas, do not install it on a box
whose databases matter. And before installing it, I strongly advise you to back
up everything concerning SQL Server 2000 that you consider even vaguely
important. I also think it would be wise to do all of this on a weekend, since
you may need the extra time to recover.
If you’ve installed SQL Express, I’d love to hear about your
experience, so please relay your thoughts on the process in the article
