Обсуждение: use of IN() with literals

I'm trying to use the following script: (to give command line ability to change grant on all tables in public in a
database)

psql -t -c “SELECT ‘GRANT $1 ON public.’ || t.relname || ‘ TO $2;’ from pg_class t, pg_namespace s WHERE t.relkind IN
(‘r’,‘v’, ‘S’) AND t.relnamespace=s.oid AND s.nspname=’public’;” $3 | psql $3 

and it always fails at the "IN(‘r’, ‘v’, ‘S’)" part. psql won't accept the literals in the IN clause. Is this normal?
Whatcould fix this? 

I've tried just doing:
(
after logging in to psql connected to a specific database)

select * from pg_class where relkind IN IN (‘r’, ‘v’, ‘S’);

and that doesn't work either.

                                           ^^  ^  ^

You repeated the keyword IN, and you are using the wrong quotes (unless this is a copy & paste problem of a broken
emailclient) 


select *
from pg_class
where relkind IN ('r', 'v', 'S');

should work

It works for me, using 8.4.2.

You have the word "IN" twice.

Yep bad scraping from one site to another. Probably encoding.

Thanks for telling me what (should) have been obvious about the two INs. The gobbledy gook was bad encoding between the
twoweb pages.
