Any user who owns the object, or has DBA authority, can execute the DROP
statement.
For DROP DBSPACE, you must be the only connection to the database.
A user with ALTER permissions on the table can execute DROP TRIGGER.
A user with REFERENCES permissions on the table can execute DROP
INDEX.
Global temporary tables cannot be dropped unless all users that have
referenced the temporary table have disconnected.
Automatic commit. Clears the Data window in Interactive SQL. DROP
TABLE and DROP INDEX close all cursors for the current connection.
Local temporary tables is an exception; no commit is performed when one is
dropped.
When a view is dropped, all procedures and triggers are unloaded from
memory, so that any procedure or trigger that references the view reflects the
fact that the view does not exist. The unloading and loading of procedures
and triggers can have a performance impact if you are regularly dropping and
creating views.
