Thread: sequences in transaction blocks

sequences in transaction blocks

From
"Marian Naghen"
Date:
I want to insert records inside a transaction block (BEGIN - COMMIT/ROLLBACK). If the transaction fails,
the sequence do not rollback and retain the new value.
 
This is the default behavior of sequences ?
 
 
I use the following table:
 
CREATE TABLE proceduri
(
  procedura_id int4 NOT NULL DEFAULT nextval('proceduri_proceduri_id_seq'::regclass),
  tip_procedura_id int4,
  ....
  CONSTRAINT proceduri_pkey PRIMARY KEY (procedura_id)
)
WITH OIDS;
 
where 'proceduri_proceduri_id_seq is:
 
CREATE SEQUENCE proceduri_proceduri_id_seq
  INCREMENT 1
  MINVALUE 1000000000
  MAXVALUE 1099999999
  START 1000000001
  CACHE 1;

Yes it is (its the whole point of sequences)
please see the docs, for example:

http://www.postgresql.org/docs/current/static/functions-sequence.html

especially the last paragraph.
