My question is whether I can create new rows for all three tables in the same sql source file. Since the location and contact tables require sequence numbers from the company and location tables is there a way to specify, e.g., current_val 'tablename PK' for the related tables? Or, do I still need to enter all new companies before their locations and contact?
Something along these lines perhaps:
=# create table a( id bigserial primary key, x text ); CREATE TABLE =# create table b( fk bigint references a(id), y text ); CREATE TABLE =# with ins_a as (insert into a (x) values ('a row') returning *)
insert into b(fk, y) select ins_a.id, 'yy'||i.i from ins_a cross join generate_series(1,10) as i(i); INSERT 0 10 =# table a; table b; id | x ----+------- 1 | a row (1 row)
