Updating upon a join - sql

Question

I can simply use a select statment on a join to pull results I'd Like using:
Select * from RESULTS (NOLOCK) left join orders on Results.ordno = orders.ordno
left join folders on folders.folderno = orders.folderno
left join pranaparms on folders.prodcode = pranaparms.prodcode and results.analyte = pranaparms.analyte
WHERE Results.s <> 'OOS-A' and Results.Final Between pranaparms.LOWERQCLIMIT and pranaparms.UPPERQCLIMIT and (pranaparms.LOWERQCLIMIT IS NOT NULL and pranaparms.UPPERQCLIMIT IS NOT NULL)
and results.ordno in (1277494)
However, is there a convenient way which I could do an update on the selected fields?
I have tried this so far:
Update RESULTS (NOLOCK) left join orders on Results.ordno = orders.ordno
left join folders on folders.folderno = orders.folderno
left join pranaparms on folders.prodcode = pranaparms.prodcode and results.analyte = pranaparms.analyte
set Results.S = 'OOS-B'
WHERE Results.s <> 'OOS-A' and Results.Final Between pranaparms.LOWERQCLIMIT and pranaparms.UPPERQCLIMIT and (pranaparms.LOWERQCLIMIT IS NOT NULL and pranaparms.UPPERQCLIMIT IS NOT NULL)
and results.ordno in (1277494)
However, it is passing an error indicating "Incorrect syntax near '('"
Is there a way for me to update off of this join or will I need to do tables individually?

Answer 1

Your select syntax suggests SQL Server. The correct update syntax in SQL Server is:
update r
set S = 'OOS-B'
from results r left join
orders o
on r.ordno = o.ordno left join
folders f
on f.folderno = o.folderno left join
pranaparms p
on f.prodcode = p.prodcode and r.analyte = p.analyte
where r.s <> 'OOS-A' and
r.Final Between p.LOWERQCLIMIT and p.UPPERQCLIMIT and
(p.LOWERQCLIMIT IS NOT NULL and p.UPPERQCLIMIT IS NOT NULL) and
r.ordno in (1277494);
Notes:
Table aliases make the query much easier to write and to read.
Do not use NOLOCK unless you know what you are doing. Given that you don't know the syntax rules for update for the database you are using, I will guess that you don't understand locks either.
Your WHERE conditions are turning the outer joins into inner joins. You should just specify the correct join type -- and probably move the conditions to the on clauses. I've left the logic as you wrote it.
