I use these cheatsheets related to TSQL and/or SQL server from time to time.
I can not count on my memory, but, it would be nice to have a photographic one.
Enough of my rambling, here is the list:

SQL Server Cheatsheet found at Scribd - http://www.scribd.com/doc/15235350/SQL-Server-TSQL-Cheatsheet
