Hi gang:
I just interviewed for a job teaching at the local college (imagine me

frightening huh?)
In any event, the interviewer asked me how long I've been using MySQL
and I replied several years. After which she asked a single question,
which was "What does EXIST mean?"
There is no 'Exist' keyword in sql, it's 'EXISTS'. Everyone seems to
know the "drop table if exists" syntax but that's not the right one they
are after (and it's non-standard sql).
There is an 'Exists' keyword for subselects. Instead of doing an IN
query, you can do an 'exists' query - but it's use is very different.
It returns true if any row in the subquery exists or false if none
exist. The idea is instead of:
select * from accounts where company_id in (select company_id from
companies where name='X');
you do
select * from company where company_id exists (select company_id from
companies where name='X');
the subselect checks the company table for the id, if it exists, the
outer query runs. It does not matter what company_id is returned from
the subquery, just that at least 1 does return.
I've never used this anywhere myself because I usually care what id's
are returned from the subquery.
(Yes, that's from the top of my head :P but here's doc's to help).

EXIST? Yeah I certainly have seen it before in the result of a mysqldump,
but from the top of my head, I probably wouldn't have known in exactly what
context it is used. I've used MySQL for 5 years now and i think if you ask
such a question, you don't know what you should be asking because the
context of EXIST is hardly ever needed, and if, if you know where to look
for it, that's more important than being able to reproduce it in from the
top of your head. It's like asking: "Do you know the syntax for ..." where
... is a rarely used function in PHP or any other language. It's like
requiring your employees to know every function of a language...

Better questions really ought to be along the lines of "how would you
tackle this problem?" and then accept a variety of answers back, or some
debugging on erroneous code. Unfortunately, these tests all too often
feature questions on those obscure functions that are rarely used.

You're making an assumption about the situation. What if it was for a
dba job or teaching advanced sql?
And 'exists' is not for mysqldump.

DROP TABLE IF EXISTS `mytable`;
I said, I've seen EXIST in a result of a mysqldump before, which is not
wrong is it? Unless I'm hallucinating... Or is EXISTS something completely
different?
And even a DBA or teacher doesn't need to know every part of syntax in
MySQL. It's more important that they know the concepts...
Anyway, I think this is all off-topic in a PHP mailing list...

DROP TABLE IF EXISTS `mytable`;
"if exists" can be used in lots of places other than "drop table", like
triggers, functions and i'm sure other things.

Yes it is completely different.

If you're going to be that pedantic, "exist" isn't in mysqldump either :P

I know it's pedantic, but unfortunately computers are strictly pedantic and
I wasn't sure why you said
"if exists" can be used in lots of places other than "drop table",
like triggers, functions and i'm sure other things."
I was just stating that I saw it in a dump and I never really used it, so
assume(d), it's not very important because you can do the same thing with IN
etc and other conditions, can't u?
Anyway, this discussion is getting rediculous. Let's move on. Didn't mean to
offend anyone here. Don't worry about answering the last question if you
also think it's irrelevant...
All good. :)

They are completely different things you're mixing up here.
"IF EXISTS" with "DROP TABLE" means "if the table does not exist, do not
give an error".
Same for "drop view", "drop trigger". If the view/table/trigger/function
does not exist, do not give an error.
"EXISTS" in a select query is a subquery - same as using "IN".
Completely different.

Right....
So, how are these different:
SELECT * FROM t1 WHERE id EXISTS (SELECT id FROM t2)
to
SELECT * FROM t1 WHERE id IN (SELECT id FROM t2)
??
According to my understanding of the documentation, these would have the
same result. Can't think of any sub query that could not have an equivalent
statement with IN (NOT IN).

Right....
So, how are these different:
SELECT * FROM t1 WHERE id EXISTS (SELECT id FROM t2)
If there are *any* results for the subselect, the exists returns true.
It's the equivalent of:
select * from t1 where id is true;
ie
select * from t1;
If there are no results for the subselect, the exists returns false, ie:
select * from t1 where false;
which will return nothing.
to
SELECT * FROM t1 WHERE id IN (SELECT id FROM t2)
this returns specific id's that match.
According to my understanding of the documentation, these would have the
same result.
No, they aren't.
create table t1(id int, name varchar(5));
insert into t1(id, name) values (1, 'one');
insert into t1(id, name) values (2, 'two');
insert into t1(id, name) values (3, 'three');
insert into t1(id, name) values (4, 'four');
insert into t1(id, name) values (5, 'five');
create table t2(id int, other_name varchar(5));
insert into t2(id, other_name) values (1, 'one');
insert into t2(id, other_name) values (2, 'two');
this returns everything from t1:
SELECT * FROM t1 WHERE EXISTS (SELECT id FROM t2);
this returns 2 rows that match:
SELECT * FROM t1 WHERE id IN (SELECT id FROM t2);

Why not preg_split ( http://nz.php.net/manual/en/function.preg-split.php ):
$str = 'SCOTTSDALE, AZ 85254';
$ar = preg_split('/,? ?/', $str); //optional comma, followed by optional
space
// $ar = array('SCOTTSDALE', 'AZ', '85254');

I am sure. In fact, the entire email header must not contain any 8-bit
characters. I.e. it _can_, but it is a violation of the standard, and
particularly in the email address it will cause problems, whereas it
will most probably work in the Subject:.

I don't know him nor the IMC, but RFC2821 is fairly clear (as clear RFCs
can be) on the matter. Still, I think this W3 webpage says it very
clearly:
http://www.w3.org/Mail/unencoded-8bits.html
"W3C's mail servers are configured to reject messages with unencoded
8bit characters in the message email headers.".

Absolutely.

Tedd, I've got a distinct feeling of deja-vu here, but Thunderbird
displays all Swiss, German, French, Greek and Danish IDNs 100%
correctly, probably many more too.
The ones you're having a problem with are the ones that allow the entire
UTF8 charset, IIRC.

If the user hits the back button and then the forward, it sometimes
resubmits the form.
This is why i initiated the session and ended it at the end of the data
processing page. If they happen to press forward, or back, it will still not
initiate the form unless they have actually visitied and submitted the form.

Cheers Ash et al... got it working now using fileread(), based on the
example on php.net. I have it in a separate download.php file which
takes a variety of inputs and spews out a file download.
Many thanks all.

I don't have the code to hand right now, but I can try and post it
later. You were on the right track with fread() et al. Basically, set
the correct headers for a download (application/octet-stream I believe)
and print out the results of the fread(). Don't forget the binary flag
on fread() if you are opening binary files, and it should create a file
that auto-downloads. There are extra headers to set the default filename
of the download, but I forget these at the moment. A Google should give
you what you need though. This way, the file can even be delivered to
someone outside of your network should you wish, without you needing to
put the file in a web-accessible directory.
