Let me just say this:
SQL - Sequential/Structured Query Language, this is a language that is an ANSI standard.
MySQL,
MS SQL,
Oracle - are Relational Database Management Systems (RDBMS), they all use SQL to access the information stored in the databases they manage.
Transact SQL - an extended version of SQL, for MS Server and Sybase, that offers more programming like structures.
Ok now that you have some definitions. All of the RDMBS' above use some form of the ANSI standard for SQL. None of them to my knowledge use the full standard. Hopefully this information will help you find what you are looking for, cause it's out there.
