Hi,

There actually is a way to update multiple rows in one UPDATE query, e.g.:

UPDATE table
SET updated_field = CASE tested_field
WHEN tested_field_value1 THEN updated_field_value1
WHEN tested_field_value2 THEN updated_field_value2
– etc.
ELSE updated_field — important part!
END

It works at least in MySQL. Probably in other databases too.

Best regards,
ChrisRaven

Very useful post. Thanx.

Is there a way to be able to insert + on duplicate update multiple rows using a single query?

Thanks for the tip.
I have one question.

>> At 2560 rows inserted, it took the loop
What if I need to send tens of thousands of records?
Will the server have any issues?
