doesn't support new introduced in MySQL 8.0.19 alias syntax like

INSERT INTO t1 (a,b,c) VALUES (%s,%s,%s) AS new ON DUPLICATE KEY UPDATE c = new.a+new.b;

while old supported values function syntax is deprecated since 8.0.20 (https://dev.mysql.com/doc/refman/8.0/en/insert-on-duplicate.html)

INSERT INTO t1 (a,b,c) VALUES (%s,%s,%s) ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);
