Re: Errors executing password change procedure

Remember that roles are handled differently by stored procedures, compared to anonymous blocks and SQL. If your procedure users definer rights (the default), it can't use privs via a role. On Wed, Nov 28, 2018 at 6:12 PM Sandra Becker <sbecker6925_at_gmail.com> wrote:

Per the requirements, I have created the new user (not allowed DBA privs) that will connect through a GUI and execute a password change procedure in another schema that has the necessary privileges. This new user has been granted execute privileges on the procedure. However, I'm getting an "ORA-01031: insufficient privileges" error when I try to execute the procedure as the new user.
