Question

How do I invoke a postgresql sequence while inserting new row into a table?

I want to do something like this:

insert into biz_term(
  biz_term_id, 
  biz_term_name, 
  ) 
values(SELECT nextval(idsequence)',
'temp'
);

I want to do it because when I am trying to insert new record into biz_term table then sequence idsequence is not getting invoked directly. How to invoke it?

Answer 1

You got it almost. You don’t need the SELECT in there:

insert into biz_term(
  biz_term_id, 
  biz_term_name, 
) 
values(
 nextval('idsequence'),
 'temp'
);

Any reasons you did not specify the biz_term_id as serial (or bigserial) which handles that automatically for you?
