Tons of duplicate questions

Also, it should be covered in any decent SQL book (I've got my understanding of the question from the O'Reilly pocket reference). Also, I still wonder where people get the old syntax examples, maybe I just learned SQL from the good sources. Also, while people repeat that both variants produce the same query with the same performance, I still prefer to doubt that when the talk is not about some DBMS specifically stating that in its documentation and especially when the talk is about DBMS in general.
