MySQL row into number of columns and sum

Question

Could somebody help with my SQL?

I have a table with records such as:

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


        

Answer 1

SELECT ROW_NUMBER() OVER(ORDER BY Car_num) Id,Car_num ,ISNULL([TV],0) [TV],ISNULL([shower],0) [shower]

FROM ( SELECT Car_num , _Service , ISNULL(Price,0) Price FROM #Table )Data PIVOT ( MAX(Price) FOR _Service IN ([TV],[shower]) )AS PVT

Answer 2

Try this:

SELECT ID, Car_num
   , SUM(IF(Service = 'shower', Price, 0)) AS Shower
   , SUM(IF(Service = 'TV', Price, 0)) AS TV
FROM your_table
GROUP BY Car_num;

Answer 3

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
