Databases

1) In the nations database on Euclid,there is a table called Religions and 
a table called nations.  Using these tables, how many Muslims are in Germany.
Show me the answer on the screen.  Half credit for doing it in two
queries and a calculator, full credit for using one query and no calculator.




2) In the nations dataase on Euclid, there is a table called nations.
The 'map' column tells you where each country is, and the pop column tells
you the population of that country.  What is the total of all the countries
in 'Europe'?  Show me on the screen.


PHP

1) When does the cookie set below expire.  This might be tricky.
  setCookie("a", "1", 2);


2) (Yes/No) Must I use mysql_real_escape_string on data from cookies if my 
program is the one that set the cookie?


3) I have a form with this bit of HTML: <input name=acre>.  How in PHP
can I tell if a user has filled in the input field?  (Just write me a line
or three, not a whole program.)




4) Suppose I do the code below.  What method(s) does this call inside the
class pig?
   $f = new pig;
   print $f;


5) Use the class 'farm' provided to print the total amount of corn
grown if I have 5 acres and each acre has a yield of 4 bushels per
acre.  Show me.




6) In the class 'farm' above, make me a local variable to some
method. It can be dumb and worthless, as long as it's a 
local variable and not a global or class variable.


7-8) Make me a php program that makes a table (of any schema).
One point for it works, two for it checks for errors too.

1) I want to be ranked highly on the phrase "professor farmer yooper".
How can I do that (15 words or less)?
