Comentário em Speed Up MySQL: Replace or On Duplicate Key Update? por Nick

You both seem to have missed the preferred solution to the indicated scenario.

In this logging situation where you are updating ONE row each time it is much better to do an UPDATE and check the number of affected rows. If zero rows are affected then follow up with an INSERT. As you will typically have many more UPDATEs than INSERTs this would be the better way although to see any real difference you need quite significant levels of concurrency.

Comentário em Speed Up MySQL: Replace or On Duplicate Key Update? por Daniel

One comment I need to make, the two functions are not identical, though I don’t see a reason to ever use REPLACE INTO.

ON DUPLICATE KEY can actually access multi-list values as well as accessing the original value of the row. For another example, consider your table with a “viewCount” column:

INSERT INTO `online` VALUES (2130706433, 1223224699, 1),(3581352818, 1223218573, 1),(1394046411, 1223218580, 1)(1452335504, 1223218580, 1) ON DUPLICATE KEY UPDATE viewCount = viewCount + VALUES(viewCount);

Of course, using VALUES() here won’t do you any good, you should just hard-code the 1 in there, but you get the point.

Note that ON DUPLICATE KEY adds 1 to the affected_rows for any INSERTS, and 2 to the affected_rows for any UPDATES, even in this format.
