Hello experts, I have a database that contains three tables:
create table a ( id serial primary key, ... -- some more fields not relevant for my question ); create table b ( id serial primary key, ... -- some more fields not relevant for my question ); create table a_b ( a int not null references a, b int not null references b ); Tables a and b have already been filled with lots of rows. Now my application needs to insert the relationship of a to b into table a_b and is currently doing it with inserts like the following: insert into a_b(a,b) values(1,100); insert into a_b(a,b) values(1,200); insert into a_b(a,b) values(1,54); insert into a_b(a,b) values(1,4577); So for a batch of inserts the value of a stays the same, while for by arbitrary values are inserted. Now I have wondered if PostreSQL offers a smarter way to insert those values? A solution can contains usage of some plpgsql code. -- ---> Dirk Jagdmann ----> http://cubic.org/~doj -----> http://llg.cubic.org ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
