SQL update multiple rows with same value

Question

I use this to update (add points) rows which mgroup is 15

UPDATE ibf_members SET points = points + 500 WHERE mgroup = 15

What can I use to update (add points + 500) for rows which has its id as 5 , 7 , 10 , 11 , 16 , 25 and also has mgroup as 15 ?

Answer 1

You can use the IN clause for this, which is easier to read (and possibly more efficient?) than building a giant OR list. Try something like:

UPDATE ibf_members
SET points = points + 500
WHERE mgroup = 15
AND id IN (5, 7, 10, 11, 16, 25);

Answer 2

只需在WHERE子句中添加另一个条件：

UPDATE ibf_members SET points = points + 500 WHERE mgroup = 15 AND id IN (5, 7, 10, 11, 16, 25)
