Im sorry but I didn't understand what you mean with the UPDATE.
Anyway, it don't apply to my point. I must do an insert in each row of my
ingresso table with his Id, some fields and the id of my cartao table.
You help is very welcomed but my solution doesn't came this time.
My best regards

Apologies – the first statement should have included the column name to
insert to:
INSERT INTO base.ingresso (id_column) (SELECT id FROM base.cartao ORDER BY
id)
That will insert one row in ingresso for each row in cartao – only
changing the id column. All the other columns in each row will be populated
with the default values. That is why you will need to do an UPDATE
afterwards. Something like:
UPDATE base.ingresso
SET col1 = 'value1', sol2 = 'value2'
WHERE id IN (SELECT id FROM base.cartao);
Hope this makes sense,
~p

The second statement works but only 1 row was affected. It do not apply to
me.
The first statement i didn't understand. You are adding only the first
field on my base.ingresso table ?

(Please reply to the list when replying)
The error is correct – you are telling PG to insert one row (the literal
values you've passed to INSERT), but the sub-query is returning multiple
rows which won't fit in a single row.
I see 2 options, but someone else I'm sure will have a more elegant way to
do it:
1) insert into base.ingresso (select id from base.cartao order by id)
2) insert into base.ingresso values (nextval(' base.ingresso_id'), 4,
now(), 12.34, 12.34, 1, 1678, (select id from base.cartao where id not in
(SELECT id from base.ingresso) order by id limit 1), 2, 25, 99)
Number 1 will create one row in base.ingresso for each row in base.cartao.
You will then need to use UPDATE to adjust the values in each of those rows
to the other values you want.
Number 2 would need to be run over and over again – not a practical option
I imagine…

Phillip,
Thank you for the information but the master (id) is only a field of my
secondary table.
My sql statement is like this:
*insert into base.ingresso values (nextval(' base.ingresso_id'), 4, now(),
12.34, 12.34, 1, 1678, (select id from base.cartao order by id), 2, 25,
99)*
And I am getting the following error return message:
*ERROR: more than one row returned by a subquery used as an expression
SQL state: 21000
*
Could you give me another help with this ?
Ezequias
