Morning John,
I tend to do something like the following (typed off top of head - there
may be typos!)
begin
FOR x IN (SELECT table_name FROM user_tables) loop
execute immediate 'drop table ' || x.table_name || ' cascade
constraints purge';
end loop;
end;
/
begin
FOR x IN (SELECT object_type, object_name FROM user_objects
WHERE object_type NOT IN ('PACKAGE BODY','UNKNOWN','DATABASE
LINK')) loop
execute immediate 'drop ' || x.object_type || ' ' || x.object_name;
end loop;
end;
/
The reason I don't drop database links is purely because we use the
above code to drop a test schema before refreshing it from live. We do
not want the database links to be recreated pointing at whatever other
production databases we use! We want to keep them pointing at test
databases.
We don't drop the schema because that messes up privs granted TO the
schema from other schemas that we are not refreshing. Grants made FROM
the test schema are refreshed when we import, so that's not a worry.
HTH
Cheers,
Norm.
