need clean way to copy col vals from one rec to another
create table foo (name text, company text, job text);
insert into foo (name,company,job) values ('joe','ge','engineer');
insert into foo (name) values ('sue');
What I want to do is map joe's company and job over to the sue record, ending up with....
'sue' 'ge' 'engineer'
Is there a quick/clever.efficient way to do this?
Thanks in Advance

UPDATE foo SET company = joe.company, job = joe.job
FROM foo AS joe
WHERE foo.name = 'sue'
AND joe.name = 'joe';
You could also do this on insert by using:
INSERT INTO foo (name, company, job)
SELECT 'sue', joe.company, joe.job
FROM foo AS joe
WHERE joe.name = 'joe';
