"Transact-SQL (T-SQL) is Microsoft's and Sybase's proprietary extension to the SQL (Structured Query Language) used to interact with relational databases." - wikipedia.org

Here are some SQL functions that can be used in a MS Server Server or Azure database. Since MS Transact-SQL is a variant of the core Structured Query Language, they can also be translated to other databases with a little effort.
