Are there any published coding style guidelines for SQL?

Question

Often I will end up with very complex SQL statements and I wondered if there was style guideline out there that dictates a common way of laying various aspects of a query out.

Answer 1

Since asking this question I have written a public SQL style guide that is compatible with Joe Celko's SQL Programming Style book under the Creative Commons Attribution-ShareAlike licence.

It is available over at www.sqlstyle.guide or as markdown directly from the GitHub repo.
