http://troels.arvin.dk/db/rdbms/ is where I go when I have to figure out
how to cope with someone's MySQL mess [this week: it lets you put an
arbitrary integer into a boolean column? seriously?]; it's also handy for
comparing against Oracle.
There is a helpful table
http://www-css.fnal.gov/dsg/external/freeware/mysql-vs-pgsql.html I refer
to sometimes. It's from March of 2005 so several pieces are out of date.
Kevin Kline's "SQL in a Nutshell" also has some helpful suggestions on
syntax differences between the major SQL dialects, but it's even older.
