Hi list,

Could someone help me with this problem

I have a table like this

Master table

id number
10 9898398398
20 9938378390
30 9873636736

and I want to make an insert into a table with this structure:

Secondary table

id(sequence), master_id
1                    10
2                    20
3                    30

It is possible to make this insert based in all records of my master table ?

Any help would be very welcomed.

Best Regards
Ezequias

INSERT INTO second_table (master_id) SELECT id FROM master_table ORDER BY id;<br /><br /> Was it important to you that
theid and master id in the second table match up? ie, 1 and 10, 2 and 20, 3 and 30 - not 1 and 30, 2 and 10, 3 and 20
etc...<br/><br /> ~p<br /><br /> On Sat, 2007-02-24 at 21:06 -0300, Ezequias Rodrigues da Rocha wrote: <blockquote

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 ?

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…

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,

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
