Try
SELECT filename,max(revision) FROM <table>
GROUP BY filename;
You can add a WHERE clause before the GROUP BY to only look at certain
filenames (e.g. WHERE filename~'foo') or if you're looking for files with a
specific latest revision number (e.g. WHERE revision=3) and an ORDER BY
after the GROUP BY (e.g. ORDER BY filename).
