Trying to update a field in an table with a sum from itself. Can't quite get the syntax down.. Here is what I have.. What am I missing.
Update EventData
Set DivTotal = (Select EventKey, SUM(EventPoints) as DivTotal
From EventData
Where eventcode = 'F'
Group by Eventkey)
I know I probably need to be doing an inner join of something to make this crude statment work, but brain not working today.
Help Please.
Ad.

This gives me the same error I was getting.. You can't use an expression in the subquery.
Error: 0x0 at Execute SQL Task: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "Update EventData

Sorry, try this:
Update e
Set DivTotal = t.DivTotal
from EventData ed
join (Select EventKey, SUM(EventPoints) as DivTotal
From EventData
Where eventcode = 'F'
Group by Eventkey) t
on ed.EventKey = t.EventKey
