hi,
How do you know that "6U7000000 443 IRA FBO Loelei C Dehart DecD W00001" is 1 row and not any other combination?
Try to add row_number to the query, the row number will give you another group by field.
something like this
select custAcctNo,custID,shortName,accountTitle
from
(select Acmnumber, dataset, stringvalue, row_number() over (partition by Acmnumber, dataset order by FIELD) as rnum from vacmvariables
where acmnumber = 153588)
up pivot ( max (stringvalue ) for dataset in ( custAcctNo,custID,shortName,accountTitle)) as pvt
order by acmnumber
