Question

Friends, I have these tables:

Contestant Table:
Winner
Peter

Group Table:
Id Name Score Union
1 Bryan 3 77
2 Mary 1 20
3 Peter 5 77
4 Joseph 2 25
5 John 6 77

I want to give additional score of 5 to Peter on Group Table. So, I came up with this query.

UPDATE Group 
SET Score = Score+5
FROM Contestant, Group 
WHERE Contestant.Winner = Group.Name

Now, I want also to give additional score of 5 to the same Union as Peter which is 77.

How can I integrate it as one query to my existing query?

//UPDATE 1

I have similar question as above but using 3 tables:

1. Company (table)
CONAME
COPOINTS

2. Group_Member (table)
CONAME
NAME

3. Member (table)
NAME
MPOINTS

I would like to have a correct query as below answer with the following condition:

Update Member
Set MPOINTS=MPOINTS+5
Where Company.CONAME=Group_Member.CONAME
And
Group_Member.NAME=Member.NAME

Can you please correct above query?

Answer 1

UPDATE Group 
SET Score = Score+5
WHERE [Union] = (
    SELECT [Union] 
    FROM Group, Contestant 
    WHERE Group.Name = Contestant.Winner)
