Sorry for this simple question but I can't seem to get Postgres to do
what I want ...
I want to get the concatenation of 2 or more tables with absolutely
nothing in common. How can I do this?
For example
Table a:
a
-----
a1
a2
a3
Table b:
b
-----
b1
b2
Table c:
c
-----
c1
c2
c3
c4
What is the proper SQL to return:
a | b | c
---------------
a1 b1 c1
a2 b2 c2
a3 c3
c4
Thanks,
Jc
