If you are using SQL Server Express Edition (SSEE), you can use the script given in that article – but you need to adjust it slightly.

SSEE won’t do an online defrag, so the script needs to be changed to always perform an offline defrag. You also need to find out the name of your content database and include that at the start of the script.

Now all you need to do is take your content database offline (you do that from the Applications Management page in your SharePoint website), and run the script.

The SQL script below is a copy of Microsoft’s script with slight modifications to make it work on SSEE.

use WSS_Content_Database;
