Re: Inserting Default Values

Hi all. I just started using postgres for a website I'm writing, and so I was messing around with some of it's features and I'm running into a little problem. Pretty much, it has to do with default values on the first column of a row. Say I have a table that looks like the following: [Table name 'test'] name | character varying(16) | id | integer | not null default nextval('"test_id_seq"'::text) If I run: sql=> insert into test values('blah'); It inserts just fine, automatically taking the default value for id. However, the table I'm actually using is the reverse of the previous. Example: [Table name 'status'] id | integer | not null default nextval('"status_id_seq"'::text) name | character varying(32) | The problem here is that no matter what I do, I can't get it to just take the default value for id. I've tried leaving a blank, followed by a comma as in: sql=> insert into test values (,'blah'); But that errors out. I've messed with using the nextval() function, but that seems to run before the actual query is run, so if there is an error in the query, my sequence goes to the next value anyways. This won't work for me because if the query fails, I don't want to have gaps in id #'s. Anyways, does anyone have any idea how to get around this problem? Any help you could give me would be great. Thanks. ________________________________________________________________________ Mike Barrett | "I used to read, now I go to raves." mike@daboyz.org | -- Random MUNI Rider, speaking www.daboyz.org | to my friend Allison. ------------------------+-----------------------------------------------
