create table todo ( id serial, task text, done_time timestamp default null );
it is legal (though perhaps not advised, by some) to query it like so:
select task, * from todo;
This gives a result with 2 redundant "task" fields (with duplicate names):
task | id | task | done_time --------------+----+--------------+----------- wash the dog | 1 | wash the dog |
However, if I try to make a view of this I hit a problem: views can't have duplicate field names:
create view task2 as select task, * from todo;
ERROR: column "task" specified more than once
I understand this may seem like a silly thing to want to do, but my question is if there is an easy way to automatically de-dup the columns of the query so I can create a view from it. Or is there any fundamental reason why views can't be allowed to have duplicate columns, just like the result set above?
