How to list the products under each category in sql? side by side

I’m a bit of a beginner in sql and I need your help.
I’m sorry that I don’t know if the question is correct.

now the code gives this;

+---------+----------+-------------+------------+
|      id | CompanyId| DealId      | price      |
+---------+----------+-------------+------------+
|       1 | 1        | 1           | 100        | 
|       2 | 1        | 2           | 50         | 
|       3 | 1        | 3           | 25         |
|       4 | 2        | 1           | 1000       |
|       5 | 2        | 2           | 2000       |
|       6 | 2        | 3           | 2500       |
+---------+----------+-------------+------------+

but this is what i want;

+---------+----------+-------------+------------+------------+--+
|      id | companyId| DealName1   | DealName2  | DealName3  |  |
+---------+----------+-------------+------------+------------+--+
|       1 |  1       | 100         | 50         |   25       |  |
|       2 |  2       | 1000        | 2000       |   2500     |  |
|       3 |  3       | value       | value      |   value    |  |
|       4 |  4       | value       | value      |   value    |  |
+---------+----------+-------------+------------+------------+--+

>Solution :

select  CompanyId 
       ,[1] as DealName1
       ,[2] as DealName2
       ,[3] as DealName3
     
from   (select CompanyId, DealId, price from   t) t
pivot  (sum(price) for DealId in([1],[2],[3])) p
