MySQL 8.0: One Giant Leap for SQL
“This is a landmark release as MySQL
eventually evolved beyond SQL-92
and the purely relational dogma.
Among a few other standard SQL
features, MySQL now supports window
functions (over) and common table
expressions (with). Without a doubt,
these are the two most important post-
SQL-92 features.”
