Hi,

I made a mistake in describing the query I tried. The query I tried was:

update new_table
set new_attribute = (select old_attribute from old_table, new_table
where old_table.id = new_table.id)
where old_table.id = new_table.id

It should be written has

update new_table set new_attribute=old_attribute from old_table where old_table.id=new_table.id;

It actually returns the error "ERROR:  more than one row returned by a
subquery used as an expression" if ran.
