Dear All,
I have a database schema consist of 3 table, I located them in 3 different workstations (Ethernet LAN) each has psql 7.1. (trying to do some parallel experiments):
the first table A, has a primary key say A.att1 (created and allocated correctly, in the first workstation)
the second table B, has primary key say B.att2 (created and allocated correctly, in the second workstation)
the third table C, has 2 Foreign key which are referenced to table A.att1 and B.att2
I have tried to create table C with those attributes as primary but I failed
create table C_ (c_att1 int4, c_att2 int4, c_att3 int4, c_att4 int4 CONSTRAINT PRIMARY KEY
(c_att1 , c_att2)); (because of the attribute duplication)
Dose any one has suggestion how to create C tale with sort of indexing...?
Thak you
Kind Regards
