Okay as I was creating my tables, it gave me the following error:
ORA-01536: space quota exceeded for tablespace 'USERS'
So I type this command to change the tablespace: ALTER USER bju5108 quota unlimited on USERS;
And then it gave me this message: ORA-00990: missing or invalid privilege
How should I fix this?
You need to run
ALTER USER bju5108 quota unlimited on USERS;
as system or sysdba.
