The MySQL >=8.0.19 supports aliases in the VALUES and SET clauses
of INSERT INTO ... ON DUPLICATE KEY UPDATE statement for the row to be
inserted and its columns. It also generates warning from >=8.0.20 if
an old style used.
This enhancement detects the MySQL version and on the base of it uses
alias during the upsert call.
Also a user can override the version through the MySQL database
configuration. It helps to save/avoid one database query
(select version()) during the upsert method call or during connecting
to the MySQL database (version is needed if strict mode is enabled).
