Get 3 tables in SQL Server 2008, avoid using two loops and Dynamic SQL

I want to get 3 tablesfrom a single table with a name @X_Table(this table has a column name original table) in SQL 2008:

There are many rows and 5 attributes in the source table (I can have more attributes like 30, but in the example I have 5 attributes):

x1  x2   x3   x4   x5    
----------------------------
438 498  3625 3645 5000
438 498  3625 3648 5000
438 498  3625 3629 5000
437 501  3625 3626 5000
438 498  3626 3629 5000
439 498  3626 3629 5000
440 5000 3627 3628 5000
444 5021 3631 3634 5000
451 5025 3635 3639 5000
458 5022 3640 3644 5000
465 525  3646 3670 5000
473 533  3652 3676 5000
481 544  3658 3678 5000
484 544  3661 3665 5000
484 532  3669 3662 2945
482 520  3685 3664 2952
481 522  3682 3661 2955
480 525  3694 3664 2948
481 515  5018 3664 2956
479 5000 3696 3661 2953 
**...(EVEN MORE ROWS LIKE 100,000)** ...

First, I get the column names in another table ( the var @table_namerefers to the table above):

INSERT  @X_Table (ID,NAME) 
SELECT  [ID] = ORDINAL_POSITION, [NAME] = COLUMN_NAME 
        FROM INFORMATION_SCHEMA.COLUMNS 
        WHERE TABLE_NAME = @table_name

So, I get @X_Table:

@X_Table:

ID  NAME
------------
1   x1
2   x2
3   x3
4   x4
5   x5

Then for each columnI sum of all values in that column therefore want all the values ​​in xi, therefore sum (x1), sum (x2), sum (x3), sum (x4), sum (x5) `

Table 1: INT, VARCHAR, FLOAT

ID Name  value
---------------------------
1   x1  48431
2   x2  138420
3   x3  192071
4   x4  192041
5   x5  204602

for each column , sum of all values in that column multiplied by each column, , x1: sum(x1*x1), sum(x1*x2), sum(x1*x3), sum(x1*x4), sum(x1*x5)
x2: sum(x2*x2), sum(x2*x3), sum(x2*x4), sum(x2*x5)
x3: sum(x3*x3), sum(x3*x4), sum(x3*x5)
x4: sum(x4*x4), sum(x4*x5)
x5: sum(x5*x5)

2: INT, VARCHAR, FLOAT

ID   Name     value
---------------------------
1   SUM(x1*x1)  83926421
2   SUM(x1*x2)  162997894
3   SUM(x1*x3)  186865166
4   SUM(x1*x4)  156224385
5   SUM(x1*x5)  168573557
6   SUM(x2*x2)  598228836
7   SUM(x2*x3)  542331010
8   SUM(x2*x4)  460990820
9   SUM(x2*x5)  512335365
10  SUM(x3*x3)  797430261
11  SUM(x3*x4)  659040569
12  SUM(x3*x5)  723779398
13  SUM(x4*x4)  677091478
14  SUM(x4*x5)  722922237
15  SUM(x5*x5)  808976398
