which they do not have any privileges?

In your multitenant container database (CDB) that contains pluggable databases (PDBs), the hr user executes the following commands to create and grant privileges on a procedure:

CREATEORREPLACEPROCEDUREcreate_test_v(v_emp_idNUMBER,v_enameVARCHA R2,v_SALARYNUMBER,v_dept_idNUMBER)
BEGIN
INSERT INTO hr.test VALUES (v_emp_id, v_ename, v salary, v_dept_id); END;
/
GRANT EXECUTE ON CREATE_TEST TO John, jim, smith, king;
