I'm trying to avoid making a thousand call like
select user1.session_id from user1.sessions;
when I could do it in a single query especially since the database is
remote and secured with SSL.
CREATE VIEW all_sessions AS
SELECT user1.session_id, 1 as user_number
FROM user1.sessions
UNION
SELECT user2.session_id, 2 AS user_number
FROM user2.sessions
UNION
...more schemas...
Then, "SELECT * FROM all_sessions" would show you each session ID (and,
with the user_number field, what user - you could use a string literal
there too). Of course, the user creating and running this would need
SELECT privileges on each schema's "sessions" table.
