MERGE is not supported by MySQL, However, there is other possible way of doing the same:

INSERT...ON DUPLICATE KEY UPDATE

If you specify the ON DUPLICATE KEY UPDATE option in the INSERT statement and the new row causes a duplicate value in the UNIQUE or PRIMARY KEY index, MySQL performs an update to the old row based on the new values.
