What sort of info do you seek? Have you tried a web search?

I recommend Google -

http://www.google.com/.

A search "characteristic functions" resulted in over 800 hits.

These included a link to the book "Optimizing Transact-SQL : Advanced Programming Techniques" by David Rozenshtein, et al. The synopsis of the book explains, "Encoded characteristic functions (ECF) is a new, innovative SQL programming methodology which allows programmers to encode conditional logic as scalar expressions within certain clauses."

Other links about "SQL & Characteristics Functions" include:
