T-SQL Update with SUM and Group BY
Solution 1
If this query returns the information you want:
SELECT *, LINE_TOTAL = SUM(l.LINE_TOTAL) OVER
(PARTITION BY l.IC_PO_HEADER, l.RELEASE_NUMBER)
FROM dbo.PO_HEADER AS h
INNER JOIN dbo.PO_LINE AS l
ON h.IC_PO_HEADER = l.IC_PO_HEADER
AND h.RELEASE_NUMBER = l.RELEASE_NUMBER;
Then this is probably the UPDATE query you want:
;WITH x AS
(
SELECT h.TOTAL, lt = SUM(l.LINE_TOTAL) OVER
(PARTITION BY l.IC_PO_HEADER, l.RELEASE_NUMBER)
FROM dbo.PO_HEADER AS h
INNER JOIN dbo.PO_LINE AS l
ON h.IC_PO_HEADER = l.IC_PO_HEADER
AND h.RELEASE_NUMBER = l.RELEASE_NUMBER
)
UPDATE x SET TOTAL = lt;
I have to agree with Gordon, your grouping seems very strange. I'm not sure if I got it right (which is why I strongly recommend you run the SELECT first).
Solution 2
It is returning more than one column because the subquery select is returning multiple rows.
Perhaps you mean something more like this:
with toupdate as (
SELECT SUM(LINE_TOTAL) AS "NEW_LINE_TOTAL"
FROM PO_LINE pl join
PO_HEADER ph
on ph.IC_PO_HEADER = pl.IC_PO_HEADER and
ph.RELEASE_NUMBER = pl.RELEASE_NUMBER
group by pl.IC_PO_HEADER, pl.FOREIGN_KEY, ph.RELEASE_NUMBER,
ph.REVISION_NUMBER, ph.PO_NUMBER
)
UPDATE PO_HEADER
SET TOTAL = toupdate. New_Line_Total
from toupdate
where PO_HEADER.IC_PO_HEADER = toupdate.IC_PO_HEADER;
I'm still suspicious of this, though, because you are grouping by 5 fields in the subquery, but only joining on one of them. I would expect "toupdate" to be grouping only on ic_po_header in this situation.

I want to update with the value in this query, but it's saying it returns more than one value.
UPDATE PO_HEADER SET TOTAL = (SELECT SUM(LINE_TOTAL) AS "NEW_LINE_TOTAL" FROM PO_LINE pl, PO_HEADER ph where ph.IC_PO_HEADER = pl.IC_PO_HEADER and ph.RELEASE_NUMBER = pl.RELEASE_NUMBER group by pl.IC_PO_HEADER,pl.FOREIGN_KEY,ph.RELEASE_NUMBER, ph.REVISION_NUMBER,ph.PO_NUMBER) from PO_HEADER ph, PO_LINE pl where ph.IC_PO_HEADER = pl.IC_PO_HEADER;
Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.How is it returning more than one column?

Shahab almost 11 yearsI am getting "Incorrect syntax near the keyword 'GROUP'" with that update statement. To test, I have created tables: create table PO_HEADER (TOTAL int, IC_PO_HEADER int, RELEASE_NUMBER int) create table PO_LINE (LINE_TOTAL int, IC_PO_HEADER int, RELEASE_NUMBER int)

Adir D almost 11 years@Ian I can't debug your query if I can't see it, sorry.
-
Shahab almost 11 yearsThanks for taking notice. The error occurs when running your update statement (after running the "create table" statements above).

Shahab almost 11 yearsThat works fine thanks. The magical "with update" statement. (P.S. why is my "@Aaron" removed from the front of my comment?)

Adir D almost 11 years@Ian because you are commenting on a post that I authored (so I get a notification without having to notify me explicitly).
