Could somebody help with my SQL?

I have a table with records such as:

ID | Car_num | Service | Price
---+---------+---------+------
1  | 001     | sh         


        

Answer 1

Use a pivot query:

SELECT MIN(ID) AS ID,
       Car_num,
       MAX(CASE WHEN Service = 'shower' THEN Price ELSE 0 END) AS shower,
       MAX(CASE WHEN Service = 'TV'     THEN Price ELSE 0 END) AS TV
FROM yourTable
GROUP BY Car_num
