The HR user creates a stand-alone procedure as follows and grants the EXECUTE privilege on theprocedure to many database users: CREATE OR REPLACE PROCEDURE create_dept ( v_deptno NUMBER, v_dname VARCHAR2, v_mgr NUMBER, v_loc NUMBER) BEGIN INSERT INTO hr.departments VALUES (v_deptno, v_dname, v_mgr, v_loc); END; The users having permission to execute the procedure are able to insert records into the DEPARTMENTStable even though they do not have the INSERT privilege on the table. You want only those users whohave privileges on the DEPARTMENTS table to be able to execute the procedure successfully. What would you suggest to the PL/SQL developers to achieve this()

Your doctor is recommending a surgical procedure you’re unsure about. Or maybe you’ve just received a diagnosis you don’t understand. Or perhaps your doctor isn’t giving you any diagnosis at all and you still don’t feel right. In all these situations, you should seek a second opinion from another physician. That’s a message most Americans don’t seem to get. According to a 2005 Gallup poll, about half of 5,000 Americans surveyed said they never seek a second opinion when their doctor “diagnoses a condition, or prescribes a treatment, drug, or operation” while just 3 percent say they always seek one.
What’s the problem? In most cases, it’s ignorance of how the healthcare system works. Patients just don’t understand that doctors think seeking a second opinion is routine. Many insurers recommend it and some even require it for certain procedures. (1)_________________.
Doctors say that both men and women should seek a second opinion in virtually all types of non-emergency surgery, when your doctor recommends long-term medication that has potential side effects and if you are not feeling better despite repeated visits to your doctor. In the first two cases, studies indicate that the second physician is most likely to confirm the initial recommendation, but may also suggest alternatives for you to consider.
(2)_________________. That’s especially true if you a get a recommendation for a hysterectomy, an operation in which the uterus is removed. It’s the second most common surgery among American women. And yet, many doctors think there are other ways to deal with some of the problems—such as uterine fibroids, pain or heavy bleeding—that lead to hysterectomies. Those other options might include medication or less drastic procedures.
Women should also seek a second opinion for unresolved cardiac problems. Until recently, for example, doctors didn’t understand that the signs of a heart attack in women can be very different from those in men. (3)_________________.
Deciding you need another opinion is the first step. How do you find the right doctor? (4)_________________.
Other resources include local medical societies, and academic medical centers, which often are the best place to find state-of-the-art treatment options. You want to find someone who is an expert on your particular problem.
(5)_________________. Dr. Jonathan Schaffer, managing director of e-Cleveland Clinic, says online second opinions are appropriate when the condition has “objective criteria”—in other words, an imaging study, stress test or pathology results. But it’s not appropriate for conditions that require more subjective interpretation, he says, such as earlier stages of breast cancer, when mammogram readings can vary and in-person consultation could be more useful.
Most of the time, the second opinion confirms the first, Cummings says, but when there is a conflict, you may have to go to a third doctor. You can also ask both of the first two doctors to explain their decisions in more detail. When the time comes to make a decision, the Ottawa Personal Decision Guide offers a step-by-step worksheet.
[A] But women in particular often say they feel awkward about consulting another doctor because they worry that their primary physician will be less than cordial in future visits. In fact, that’s rarely the case.
[B] Another possibility is an online consultation, offered by the Cleveland Clinic, among other places.
[C] In addition to these general recommendations, women should get a second opinion for certain issues specific to gender.
[D] Many physicians suggest starting with your primary-care doctor.
[E] Consulting another doctor will be a fashion in developed countries, especially in the United States.
[F] Tests given to detect heart disease in men may not always be sensitive to women’s heart problems so if you get an all-clear but continue to experience symptoms such as shortness of breath or periods of rapid heartbeat, you should seek another opinion—preferably from a specialist in women’s heart disease.
[G] You must first get the permission of Ministry of Health, and under the supervision of Government’s health care system if you need a second opinion.
