I need to make update of table1 with data on table2 in the order of id

that looks like EAV. is it?

Err, I don´t know so much about EAV, so I think that isn´t. I´m just trying to reproduce a calc in a spreeadsheet.

There are some way to do this with a UPDATE statement ?

to do it with an update statement you need no more than one rows in the
from for each row in the target.

easiest non update statement approach is probably to use a plpgsql 
function with a loop.

basically you need to find another way to do it.

Ok! I make a function in plpgsql to do it.

Thank´s again !
