tables not in list

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.

Lee

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

I usually resolve this as:
-- this function lets you select from an array
CREATE OR REPLACE FUNCTION "array_to_set" (vaarray anyarray) RETURNS
SETOF anyelement AS
$body$
BEGIN
FOR I IN COALESCE(ARRAY_LOWER(VAARRAY, 1), 1) ..
COALESCE(ARRAY_UPPER(VAARRAY, 1), 0) LOOP
RETURN NEXT VAARRAY[I];
END LOOP;
END
$body$
LANGUAGE 'plpgsql';

select table_name
from array_to_set(array['test', 'bar', 'foo']) as table_name
where table_name not in (select table_name from
information_schema.tables where table_catalog='postgres' and
table_type='BASE TABLE' and table_schema='public')

regards
