dear SQL friends,

What I want to do might be done differantly. Right now I can't
think of another solution other than a select statement

I would like to create a sequence range of integer constants. Join
this sequence against a ID Range in a database and look for missing
Id's.

Another application for this would be to simply populate a database with
say 1000..9999 Records....

Now: Is there a syntax that allows for the following.....

create table XX (id int);
insert into XX (select xx from "1 to 1000" of integers)

or...

select IntSeq.MissingValues, x.UniqIntId,x.A,x.B,x.C,
from MyDataTable x
left outer join
(
select MissingValues from "1 to 1000" of integers
) IntSeq on MissingValues=x.UniqIntId


I'm hoping that someone has done this and might be able to
point to some function or methode to do this

Thanks,

Stefan Becker

Perhaps you are searching for generate_series():

test=*# select generate_series(1,10);
generate_series
-----------------
1
2
3
4
5
6
7
8

10
(10 rows)

select * from generate_series(1,1000);

Maybe something like this will help:

SELECT id
FROM generate_series(1, (SELECT last_value FROM id_seq)) AS s(id)
EXCEPT
SELECT UniqIntId FROM MyDataTable
ORDER BY id;

The id_seq is the sequence on your ID column, assuming it has one, or
you can replace the (SELECT ... FROM id_seq) by 1000.
