Re: Insert Question

I would look at creating a temp table as:

select product_number,generate_series(4200001,4200001+(select count(*) from product_number)) order by product_number;

Then rename the temp table back to the original table.

Subject: [NOVICE] Insert Question

hhi all,

long time no askie question, but here goes...

i want to insert sequential document numbers into a
products table

my current setup is like so:

product_number document_number
1001
1002
1006
1005

i want an insert statement that will yield the
following:

product_number document_number
1001 42000001
1002 42000002
1006 42000003
1005 42000004

relative order means nothing, but i do want sequential
document numbers.

how can i go about getting this done as efficiently as
possible?

as always, tia.
