Hi,
I am trying to do a 2 joins between 3 tables.
ie)
select <some field>, coalesce(TRR.ABC, SOC.ABC) as newABC, ...
from A join (B join C on (..)) on (..)) as TRR
left join
(D join E on (..)) as SOC on (TRR.Field1=SOC.Field2)
When I run this it says that there is an ambiguous field. Yes after the
join for TRR and SOC they both contain a fields name ABC. How can I
rename this field in the sql statement or how can I make it so the sql
statement know that they are different.
Please help.. .thanks
