sql - MySQL bulk INSERT or UPDATE

Question

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).

Answer 1

You can insert/update multiple rows using INSERT ... ON DUPLICATE KEY UPDATE. The documentation has the following example:

INSERT INTO table (a,b,c) VALUES (1,2,3),(4,5,6)
ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);

Or am I misunderstanding your question?
