The MySQL-documentation keeps mentioning a so called “table_reference”. But I’m not sure what exactly is a table reference and what’s not! Searching the documentation didn’t get me any further either..
What I need to know is if a JOIN is a table reference, if an inner SELECT is one and so on. I could simply try but I hope someone has a better resource that keeps track of this stuff!
If you read the doc page you linked, it links to definitions of table_references, which eventually end up here: http://dev.mysql.com/doc/refman/5.6/en/join.html
