This plugin enables SQL syntax highlighting inside single-quoted multiline strings in a Python file. It is heavily based on Kris Jenkins's vim-python-sql plugin, from which the rest of this README is copied with little modification:

• Install Pathogen. (You're already using Pathogen, right?)
• Clone this project into ~/.vim/bundle/vim-python-sql.

Whenever you edit a Python file, multiline single-quoted strings (those delimited with '''...''') will be highlighted as SQL.

Matches are case-sensitive, because that's my preference, but it's trivial to fork & change the matching rules to suit your coding style.

This repo serves as a reasonable recipe for embedded Vim syntax highlighting in general. It could easily be forked for highlighting SQL in Hibernate XML files, for example.

Thanks to Max Bane who figured out the hard stuff when when mixing Tex with Python.

vim-clojure-sql - the same plugin for SQL inside Clojure files.
