Here's the workflow that most organizations use:

• When you make a production release, you tag it. In SVN, this is done with svn cp, copying trunk into a named directory under tags.
• If you need to make bugfixes to a production release, you use svn cp to copy the tagged revision into a branch under branches. You then check out this named revision, make your changes, and check in.
• If you're going to push the changes out to production, you can tag them from the branch, again using svn cp. Tags are cheap in Subversion.
• If the fixes you made in the branch need to go back into trunk, you can merge them.

This is covered in the docs (this is a link to the chapter on branching and merging, but I recommend you read the introductory material if you're not familiar with SVN).

Read chapters 2 and 3 and that will be enough to hit the ground running. The command you are likely looking for is svn update -rNNN however, without some background on SVN odds are excellent that you'll misuse it as SVN is very like (yet in some ways different) than the old school CVS, RCS, SCCS like systems.

You might want to skim chapter 1 too, as the revisioning model SVN uses is a little different than tight locking models (if you've been using one of those).
