Обсуждение: Serial data type not starting at 1
Hi, I hope someone can help me. I want to create a new table using the "automatic" sequence function of Postgres by creating the first column as type "serial". But I want to start at say "5000". Can it be done, and how? Thank you Tielman J de Villiers BondNet Pty Ltd
Great and thank you very much:
[ create table test2 (x int default nextval('test_serial'),y varchar); ]
Did the trick

create sequence test_serial start 5000;
create table test2 (
x nextval('test_serial'),
y varchar;
);

I would think you can use setval() on the sequence created by the serial before any rows are inserted in order to start at a different value.

I don't think you can do it within the table definition, but you can certainly use setval() to change the value after the table has been created. -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > Magnetism, electricity and motion are like a three-for-two special offer: > if you have two of them, the third one comes free.

create sequence test_serial start 5000;
create table test2 (
x nextval('test_serial'),
y varchar;
);

Thanks Tony, I have tried: db=> create table test2(x serial start 5000,y varchar); But it gives: ERROR: parser: parse error at or near "start" Tielman J de Villiers BondNet Pty Ltd -----Original Message----- From: tony [mailto:tony@animaproductions.com] Sent: Thursday, November 15, 2001 4:41 PM To: Tielman J de Villiers Cc: 'pgsql-general@postgresql.org' Subject: Re: [GENERAL] Serial data type not starting at 1 On Thu, 2001-11-15 at 14:50, Tielman J de Villiers wrote: > Hi, > > I hope someone can help me. > > I want to create a new table using the "automatic" sequence function > of Postgres by creating the first column as type "serial".
