Is there any way of performing in bulk a query like INSERT OR UPDATE
on the MySQL server?
INSERT IGNORE ...
won't work, because if the field already exists, it will simply ignore it and not insert anything.
REPLACE ...
won't work, because if the field already exists, it will first DELETE
it and then INSERT
it again, rather than updating it.
INSERT ... ON DUPLICATE KEY UPDATE
will work, but it can't be used in bulk.
So I'd like to know if there's any command like INSERT ... ON DUPLICATE KEY UPDATE
that can be issued in bulk (more than one row at the same time).
