function oversight for SQL server

Has anyone a reference on a comprehensive oversight of functions available for SQL server? I suspect that some special functions like in DB2 or ORACLE are not available with SQL server, but I want to do a comparison.........Look in bol - it gives a list of functions.
There may be things that are available in other databases but not in sql server but that may well be because sql server concentrates more on database functionality and expects the system to be designed as such.|||Originally posted by nigelrivett

Thanks for the suggestion,

However, i am not looking to buy a book, just need a list of functions that i can download from a SQL server related site...
functions I am refering to are, among others things like RANK(), which to me are perfectly handy in a SQL tool-set...|||Here is a start...
