I wrote an SQL formatter as part of a larger source-to-source compiler for a re-engineering tool many years ago and ended up with initial caps for SQL keywords.

I wrote an SQL formatter as part of a larger source-to-source compiler for a re-engineering tool many years ago and ended up with initial caps for SQL keywords. E.g. Select * From sometable Where SomeColumn > 3 It doesn't SCREAM but provides some visual handle for spotting the keywords. It's particularly effective if the table and column names use a lowercase convention which many of systems we had to deal with did.
