I'm using SQL server 2012 and I'm trying to sum rows of a table. Problem is I don't have a column to group by. Is this possible...? How would you raise the query? 

Original table:

```
+----+------+--------+
| ID | User | Salary |
+----+------+--------+
| 1  | John | 150    |
| 2  | Marie| 120    |
| 3  | Willy| 125    |
| 4  | Juan | 110    |
| 5  |Carlos| 145    |
| 6  | Mike | 115    |
| 7  | Elsie| 100    |
| 8  | Elvie| 500    |
+----+------+--------+

```

Expected Result:

```
+----+--------+--------+
| ID |  USER  | SALARY |
+----+--------+--------+
|  1 | 1plus2 |    270 |
|  2 | 1plus3 |    275 |
|  3 | 1to4   |    205 |
|  4 | 1plus8 |    650 |
+----+--------+--------+

```
