postgresql - Can I use return value of INSERT...RETURNING in another INSERT? -


is possible?

insert table2 (val) values ((insert table1 (name) values ('a_title') returning id));

like using return value value insert row in second table reference first table?

you can starting postgres 9.1:

with rows ( insert table1 (name) values ('a_title') returning id ) insert table2 (val) select id rows

in meanwhile, if you're interested in id, can trigger:

create function t1_ins_into_t2()   returns trigger $$ begin   insert table2 (val) values (new.id);   return new; end; $$ language plpgsql;  create trigger t1_ins_into_t2   after insert on table1 each row execute procedure t1_ins_into_t2();
