Logged by: zam6ak
Email address: zam6ak@gmail.com
PostgreSQL version: 10beta1
Operating system: Windows Server 2012 R2
Description:
I have downloaded a PG10 distro for Windows from BigSQL.
if I try to update table that uses identity column generated always, the
update fails...
If I switch to "generated by default" it works...
-- create tbl1
create table tbl1 ( id bigint GENERATED ALWAYS AS IDENTITY PRIMARY KEY, -- fails --id bigint GENERATED BY
DEFAULTAS IDENTITY PRIMARY KEY, -- works name text NOT NULL
);
-- add some values
insert into tbl1 (name) values ('Tommy');
-- verify
select * from tbl1; -- 1;"Tommy"
-- now try to update
update tbl1 set name = 'Bobby' where id = 1;
ERROR: column "id" can only be updated to DEFAULT
DETAIL: Column "id" is an identity column defined as GENERATED ALWAYS.
********** Error **********
ERROR: column "id" can only be updated to DEFAULT
SQL state: 428C9
Detail: Column "id" is an identity column defined as GENERATED ALWAYS.
