Обсуждение: drop all tables in db - without dropdb ?!

hi there,

i would like to drop all tables in a database without
having to issue individual drop-statements for every
table.
is there a command that can do this?

i can not use the dropdb since i do not have the
permissions :(

thnx
L

If you're usng 7.4, you can drop the public schema, which will drop all
objects in it:

DROP SCHEMA public CASCADE;

However, you may not have permission to do that either.   In that case, no,
you're stuck with one-by-one dropping.   I suggest either getting greater
permissions, or writing a quick script in Perl.

You could do:

  DROP SCHEMA public CASCADE;

if you have permissions for that.  (It would delete functions and so on
as well, not just tables.)


Or you could do it in shell script:

psql -t -d my_dbname -c "SELECT 'DROP TABLE ' || n.nspname || '.' ||
c.relname || ' CASCADE;' FROM pg_catalog.pg_class AS c LEFT JOIN
pg_catalog.pg_namespace AS n ON n.oid = c.relnamespace WHERE relkind =
'r' AND n.nspname NOT IN ('pg_catalog', 'pg_toast') AND
pg_catalog.pg_table_is_visible(c.oid)" >/tmp/droptables

psql -d my_dbname -f /tmp/droptables
