This might help you , You could use some thing like this HTML
code :
<table>
<thead>
    <th>Item</th>
    <th>Cost</th>
</thead>
<tbody id="tbody">
    <tr>
        <td>Item 1</td>
        <td>
            <input type="text" class="elm" />
        </td>
    </tr>
    <tr>
        <td>Item 2</td>
        <td>
            <input type="text" class="elm" />
        </td>
    </tr>
    <tr>
        <td>Item 3</td>
        <td>
            <input type="text" class="elm" />
        </td>
    </tr>
    <tr>
        <td>Item 4</td>
        <td>
            <input type="text" class="elm" />
        </td>
    </tr>
    <tr>
        <td>Item 5</td>
        <td>
            <input type="text" class="elm" />
        </td>
    </tr>

</tbody>
<tfoot>
    <tr>
        <td>Total</td>
        <td>
            <label id="total">0</label>
        </td>
    </tr>
</tfoot>
    $('body').on('keyup','.elm',function(e){
    //Check Key Press is Enter
    if (e.keyCode != 13) {
        var sum = 0;
        $('.elm').each(function() {
            if($(this).val() != '' && !isNaN($(this).val())){
                sum += parseInt($(this).val());
            }
        });

        $('#total').text(sum);
    }
    else{
        var itemNum = $('#tbody tr').length + 1;
        var newRow = '<tr>'+
            '<td>Item'+itemNum+'</td>'+
            '<td>'+
                '<input type="text" class="elm">'+
            '</td>'+
        '</tr>';
        $('#tbody').append(newRow);
    }
});

wish help you to fix your issue this should do it (assuming your 'data' column is in fact a datetime, and your user input is a string). Two separate queries to get the lower and upper values, then join together with UNION :
code :
(SELECT * FROM myTable WHERE STR_TO_DATE('07.11.1986', '%d./%m./%Y')  < data ORDER BY data ASC LIMIT 1)
UNION ALL
(SELECT * FROM myTable WHERE STR_TO_DATE('07.11.1986', '%d./%m./%Y')  > data ORDER BY data DESC LIMIT 1)

will be helpful for those in need Well, how about you take each user input, and...add it to a list? Wow, I know, cutting edge. Then, I don't know, maybe do some operations on that list that find the min and max? Here's an example. If this is homework, you're better off rewriting for yourself. And if you're using Python 2.x, as your updated question indicates, you're going to have to modify what I'm giving you either way, because it is for Python 3
code :
numberlist=[] #where we're storing our data
while True:
  print("Please enter a number, or 'Done'")
  newdata=input()
  if newdata == 'done' or newdata == 'Done' or newdata == 'DONE': #only gave options here because I typed the wrong case in while testing
    break #breaks the loop when done is entered
  numberlist.append(newdata) #adds the number entered to our list
print("List of numbers: "+str(numberlist))  
print("Min: "+min(numberlist)) 
print("Max: "+max(numberlist))

Hope that helps Going through a bit at a time: although wildcard imports are generally frowned upon, it is more usual syntax to use
code :
from turtle import *
from math import *
import math
a = float(input("enter the value for a: "))
b = float(input("enter the value for b: "))
c = float(input("enter the value for c: "))
if (a + b >= c) and (b + c >= a) and (c + a >= b):
    print("it's a triangle")
else:
    print("it's not a triangle")
A = degrees(acos((b**2 + c**2 - a**2)/(2*b*c)))
B = degrees(acos((c**2 + a**2 - b**2)/(2*c*a)))
C = degrees(acos((a**2 + b**2 - c**2)/(2*a*b)))
from turtle import *
from math import *
import math

a = float(input("enter the value for a: "))
b = float(input("enter the value for b: "))
c = float(input("enter the value for c: "))

if (a + b >= c) and (b + c >= a) and (c + a >= b):
    print("it's a triangle")

    A = degrees(acos((b**2 + c**2 - a**2)/(2*b*c)))
    B = degrees(acos((c**2 + a**2 - b**2)/(2*c*a)))
    C = degrees(acos((a**2 + b**2 - c**2)/(2*a*b)))
else:
    print("it's not a triangle")

this one helps. A little off-topic but if you must store unique elements, you normally go for a Set. That being said, in the portion of the code where you collect the user input, you are asking for 5 numbers but storing 4 e.g.:
code :
   int count = 0;     
   while (true) {
       int a = 0;
       while(true) {
           System.out.print("Enter an integer between 10 and 100:");
           a = Integer.parseInt(sc.nextLine());
           if (a < 10 || a > 100)
              System.out.println("Invalid input\n");
           else
              break;
       }  
       // count++;
       // if (count == 5) if you break here, the code below won't be reached
       //   break;        thus you will never store the last user input 

       // Lists have a method contains that does exactly what you are trying to do
       // Consider using ifExists = userInput.contains(a)
       boolean ifExists = false;             
       for(int i = 0; i<userInputs.size(); i++) {
          if (userInputs.get(i) == a) {
             ifExists = true;
             break;

          }
       }
       if (!ifExists){
          System.out.printf("This is the first time %d has been entered\n", a);
          userInputs.add(a);
       }      
        // consider breaking here after you have collected the last user input
        // alternatively, use a do{ ... } while(); loop
        count++;
        if (count == 5)
            break;
   } // end while statement
// output unique values
System.out.println("\nThe complete set of unique values entered is:\n");
for(int i = 0; i < userInputs.size(); i++) {
    System.out.println("Unique Value " + (i + 1) + ": is " + userInputs.get(i));
}

Any of those help You can find all combinations of 1 or two invoices that meet your conditions:
code :
select d1.invoice, d1.price,
       (case when d2.invoice <> d1.invoice then d2.invoice end) as invoice2,
       (case when d2.invoice <> d1.invoice then d2.price end) as price2
from data d1 left join
     data d2
     on d1.invoice <= d2.invoice
where (d1.price = 500 and d2.invoice = d1.invoice) or
      (d1.price + d2.price) = 500
