Обсуждение: Missing table from in INSERT RETURNING

I haven't seen any one else reply. I don't know if you've gotten a solution. But the following seemed to work for me:

WITH serie AS (

select s, s*10 as computing

from generate_series(1,10) as s 

)

INSERT INTO test_insert_returning (some_value)

SELECT computing

FROM serie

RETURNING gid, some_value;

From my reading on the RETURNING phrase, you can only return values from the table into which you are doing the INSERT. Not any other table or view which might be referenced.

Hello dear list,

I would appreciate some help on a small matter that has been bothering me for a long time :

CREATE TABLE test_insert_returning( 

gid SERIAL

,some_value int 

);

WITH serie AS (

select s, s*10 as computing

from generate_series(1,10) as s 

)

INSERT INTO test_insert_returning (some_value)

SELECT computing

FROM serie

RETURNING gid, serie.s

doesn't work.

The only workaround I found was to create a plpgsql function that doesan idnividual insert

so that :

WITH serie AS (

select s, s*10 as computing

from generate_series(1,10) as s 

)

SELECT serie.s, my_inserting_function(computing)

FROM serie ;

But it is very annoying and potentially bad for performance because many insert may be fired.

Any solution?
(postgres 9.3)

from generate_series(1,10) as s

INSERT INTO test_insert_returning (some_value)

SELECT computing

FROM serie

RETURNING gid, some_value;

​or, "RETURNING some_value / 10"​

​This is correct; and I am curious on the use case that requires otherwise.​
