Bill,
Pull out the big cannon and go boom:
export the CREATE USER to create_user script
write a script containing:
DROP USER uname CASCADE;
@CREATE_USER
run this new script.
have beer.
Now of course, this will not be as fast as a parallel
DROP TABLE user.tab CASCADE CONSTRAINTS, but hey, more
time to have beer.
hth,
Jack
