Re: How do they get the answer?
an assumption is made that the same 2 teachers are not teaching subject 102 and 105 for if they were then, only 2 teachers would be getting raises. but if you go with 4 different teachers are teaching that class(2 groups of 2) then answer c would be correct.

RE: How do they get the answer?
Title: RE: How do they get the answer? My thoughts are Typical OCP question. a) Could be the answer depending on if both the subjects are taught by the same 2 teachers b) Cannot be the answer because only 2 subjects are mentioned (102,105) c) Could be the answer if the 2 subjects are taught by 4 different teachers (not it cannot be more than 4 therefor the 'at least 4' is misleading d) If a syntax error did occur you would correct and run again so why you should fail the OCP question for that reason is bizarre anyway.

The answer must be AT LEAST 2 Teachers . Because lets say two teachers Rick and Susan. Susan gives the subjects 102 and 105 Rick gives the subjects 102 and 105 Nobody else gives these subjects.

Re: How do they get the answer?
This is a poorly written question. I would guess that since it is the teacher table the assumption is that the ID is unique, even a primary key (it is not null), but none of this is stated so it doesn't have to be the case. Although I can't see it making any sense to repeat the salary (if indeed this is the salary for the teacher rather than the course), if a teacher can be in more than once that block could be used an example of an update not doing what was expected. The update is done on subject_id and it is the record with that subject_id. If a teacher is teaching more than one course and the salary if for the teacher rather than the course, we end up with the possibility of different salaries for the same teacher and if the teacher happened to be teaching both and therefore was to get two raises what happens but those two records are now consistent at the wrong value. Of course with what info is given in the question there are other possibilities for what the table really represents and what the PL/SQL block is supposed to do. I would think an essay question on what is going on would be more revealing of the individual's knowledge than a flawed multiple guess question. I don't think I have ever heard of it for anything other than true-false but justifying the selection might make it a little more useful. Pat Examine the structure of the TEACHER table: Name Null?

Re: How do they get the answer?
well we know the answer is C, but its the most correct out of the 4, not
necessarily the ultimate correct answer.

It's possible, but not the only possibility. Therefore you
can't answer A.
And if you're not certain, you can't answer the question. Because this
is the Oracle OCP exam. The thing that you've studied night and day
for. Everything you learned in the two-night class preparing you for
database administration and nuclear physics. This is crunch time, baby -
right or wrong? You make the call. Pressure's on. Which will
it be? What if this is the question that will put me under that
passing grade. A or C? A or C? Which will it be? What
will I do? You want the truth? You want the truth? You
can't handle the truth!
I'm heading back to the espresso machine now...

Re: How do they get the answer?
The structure of the table indicates to me that they began with the assumption that each teacher would only be teaching one subject.

Yes, if 102 and 105 are valid subject_id codes. The correct answer is Not enough data has been supplied to properly evaluate the results. David A.

Re: How do they get the answer?
Each subject has 2 teachers. By limiting the update by 2 subject_id's, you guarantee that 4 teachers will get a raise. Actually, this is poor SQL if a teacher teaches more than one subject (but that's not part of the problem).
