Thanks for all who assisted with my previous question on grouping.
I would like to do an update of a table with the results of a query on
another.
For example:
table vehcost
id serial
po varchar(12)
veh_no varchar(8)
cost real
comments varchar(30)
table vehinfo
id serial
veh_no varchar(12)
m_cost real
...
I would like to take the sum of vehcost.veh_no and update that info to
field vehinfo.m_cost.
So far, I have worked with the following without success:
update vehinfo set m_cost = (select sum(vehcost.cost) from vehcost group by
veh_no) where vehinfo.veh_no = vehcost.veh_no ;
Any ideas.
Thanks in advance for any assistance.
