is this possible

hey all,
what's the best way to get all the records in a master table and a sum of a
column in a related details table?
thanks,
rodcharThe best way is to post DDL and sample data (
http://www.aspfaq.com/etiquette.asp?id=5006 )
But...
SELECT Master.PKCol, SUM(Detail.SomeCol) SumSomeCol
FROM Master
JOIN Detail ON Master.PKCol = Detail.PKCol
GROUP BY Master.PKCol

select m.id,sum(c.col)
from master m left join child c on m.id=c.fk
group by m.id

u
the answer. Once you have it, it will be obvious how it should be assemble t
o
get those things you need.
Vagueness begets vague answers. Post DDL

(SELECT SUM(<col_name> )
FROM details_table AS D
WHERE D.referencing_col = M.referenced_col) AS sumdetail
FROM master_table AS M
