How do I run a T-SQL query to loop through all databases?

Find out how to run a T-SQL query to loop through all databases.

I have a shared Microsoft SQL Server that has over 100 databases on it. The log files are getting outrageously large and I'm trying to conserve some disk space. Rollbacks to specific transactions aren't important. I would like to change all the databases to SIMPLE recovery mode so I can run an auto-shrink each night. Unfortunately, I can't find anything that explains how to run a T-SQL query to loop through all databases. Is this possible? If so, can you provide an example of how to do this?

Run this command:

EXEC sp_MSforeachdb @command1="print 'ALTER DATABASE ' + ('?') + ' SET RECOVERY SIMPLE'"

Then you can copy the output from this query and paste into another query window to actually change the settings. You can also remove the system databases when you select from the output, so you don't change these databases.
