roles are never enabled during the execution of a procedure except in the special case of Invokers Rights which is a new feature in Oracle8i, release 8.1.

This fact is documented application developers guide:

<quote>
Privileges Required to Create Procedures and Functions

To create a stand-alone procedure or function, or package specification or body, you must meet the following prerequisites:

• You must have the CREATE PROCEDURE system privilege to create a procedure or package in your schema, or the CREATE ANY PROCEDURE system privilege to create a procedure or package in another user’s schema.

Attention: To create without errors, that is, to compile the procedure or package successfully, requires the following additional privileges: The owner of the procedure or package must have been explicitly granted the necessary object privileges for all objects referenced within the body of the code; the owner cannot have obtained required privileges through roles.

If the privileges of a procedure’s or package’s owner change, the procedure must be reauthenticated before it is executed. If a necessary privilege to a referenced object is revoked from the owner of the procedure (or package), the procedure cannot be executed.

Try this:

SQL> set role none;
SQL> "statement you want to test to see if it'll work in a procedure"

If you can do it in plus with no roles you can do it in a procedure. If you can't, you must have the privelege from a role and hence won't be able to do it in a procedure.

You probably have the privelege to do what you are trying to do in the procedure via a role. Grant the privelege directly to the owner of the procedure and it'll work.
