Hey everyone, I'm having trouble with this question. Its an SQL statement:

FROM Contacts
WHERE State = "NSW"
SELECT Firstname, Lastname, Email
ORDER Lastname, Firstname

The bold bit is the part I dont really understand.....Whats ORDER actually mean? In the standards package they set it out like:
Firstname, Lastname, Email

The the ORDER says its Lastname, Firstname *confused*

If I attempted the question it would be like:
Lastname, Firstname, Email

But the right answer is Firstname, Lastname, Email

Could someone plz explain why it is like this? And what ORDER means? Thanx in advance:)

I got confused too at first.
SELECT Firstname, Lastname, Email

means selecting data from those fields

ORDER Lastname, Firstname

means write your answers showing the Lastname first then Firstname then Email

I think the right answer is wrong.

The answer should be:
Lake | Fred | lake.fred@supersys.com.au
Lee | Bianca | b.lee@cruz.com.au
etc.

Order simply means to put it in order.
Example
From Table: Contacts both Lees are from NSW
So how do u order?

Firstly order by Lastname, so first up is Lake, then Lee. There r TWO Lees, so sort their Firstname.

So basically my result from the above query for Q18 (e) is...

Lake Fred lake.fred@supersys.com.au
Lee Bianca b.lee@cruz.com.au
Lee Judy j.lee@eop.com.au
Nguyen Tranh t.nguyen@cruz.com.au

I read the notes from the marking centre & u'd still get full marks whether Lastname is b4 of after. It doesnt matter, either way u still get full marks. But jus be a bit careful with these types of question. Best thing is to go practice ur SQL.

i just looked at the notes and i didnt see that there, FreedomDragon ?

I think that Firstname is first because of its positioning within SELECT....

select fa,fb,fc from ....
return the fields fa fb and fc in that order

The ORDER just detremines how the three fields will show up but the SELECT says in which order the fields to BE ordered are to be displayed...thats a bit long winded hope u can understand

Hmmmmm I had another look at it today.. I'm thinking the same thing.. SELECT means which way it will show up..Which is first name, lastname, email
ORDER means in which order it will turn up.. In this case in alphabetical order... Thats wot i think..

FROM= which table or entity
Select= Fields to be display
WHERE= the criterial
ORDER BY= order the records, either decending or ascending

Ive read the notes AGAIN from the marking centre and i must have miss read it this morning at a glance. Sorry about that.

Yes, about the order in which it is displayed is supposed to be Firstname, Lastname, Email.
I checked my SQL book, indeed the order that the field is SELECT is the order that it will be displayed.

So once again
Fred Lake email
Bianca Lee email
Judy Lee email
Tranh Nguyen email

Oh ok. So the answer was right then. I can't believe my TAFE teacher was wrong. What a shame!

Ok anyone done Q22, the last long response question, for 2001? I think it was the hardest of the three...hmm im quite dramatically confused with it. Here's the question:

The organisation is seeking to improve data management. Write a report that proposes good file-management procedures. Include a simple sketch of a directory/folder structure for the Sales Department using information from the hierarchy diagram. Explain and justify your proposals in relation to audit requirements, file attributes, incremental backup and file and folder passwords.

the organisational chart also goes with it. Anyone that could help out, thanks =)
