insetion request and update in the same time

Question

hi, I'm looking on the net a query that allows for the inserting if there are no duplicates and  update if I find a duplicate, I find this syntax query

 

 INSERT INTO table (a, b, c) VALUES (1, 20, 68)

ON DUPLICATE KEY UPDATE a=a+1

 

in this links SQL ON DUPLICATE KEY UPDATE

but he says it is a MySQL functionality.

Does there-an equivalent of this in Access?
