Subject: Re: I need to do a sum on a secondary (left outer join)
table...
Use ISNULL()
SELECT ..., SUM(ISNULL(secondary.received,0))
.
This will assign 0 to any rows that don't have a value in that column.
Or don't use an OUTER JOIN :D

Is there a way to grab all the records from one table and sum up all
the
values of a column from another table based on a foreign key?
This is what I'm trying to do:
SELECT primary.primary_id, primary.initiated, primary.completed,
SUM(secondary.received)
FROM primary LEFT OUTER JOIN secondary
ON primary.primary_id = secondary.primary_id
