Re: tables not in list

Is there no way to do this without doing an insert into another table?

put all your tables in a new table (public.tables)

select table_name from public.tables

where public.tables.table_name not in (select table_name from
information_schema.tables where table_catalog='postgres' and
table_type='BASE TABLE' and table_schema='public')

Hi List,

I have a list of table names and I am trying to confirm that they are all in
my postgres db. But what I want returned is a list/array of ones that are
in my list but not in the db. So for example:

CREATE TABLE test

(

somecol integer

) WITHOUT OIDS;

CREATE TABLE bar

(

barcol integer

) WITHOUT OIDS;

Now if I were to have a list of table names that included 'test', 'bar', and
'foo', then how do I get 'foo' to return. Here is what I have, but it
returns the ones that are in the list and I want the opposite of that.

select array(

select table_name::text from information_schema.tables where
table_catalog='postgres' and table_type='BASE TABLE' and
table_schema='public'

and table_name = any (array['test', 'bar', 'foo']))

Thanks in advance for any help on this.
