How to get data from 2 rows which has same data in all columns except one in MSSQL - sql

Question

As in my title I want to take data from 2 rows but In my case each 2nd row has one different value compare to the first row.
I want to take all the common data along with the different data as a single row .
Here you can see each row has same values in another row except the 2nd rows last column.
Thanks.

I suspect you have a some kind of ordering columns that could specify your actual data ordering if so, then you can use row_number() function
select * from (
select *,
row_number() over (partition by <common data cols> order by ? desc) Seq
from table t
) t
where seq = 1;
EDIT : I don't believe your inventort_item_id columns but yes you could use creation_date for ordering purpose
SELECT
EPI.ITEM_CODE, LMP.PROD_DESC, LLPC.COLOC_PROD_PRICE,
BASE_PATH + '' + EPI.IMAGE_FOLDER_NAME + '/' + EPI.IMAGE_DESCRIPTION AS POPULAR_PRODUCTS_IMAGE_PATHS
FROM (SELECT *,
ROW_NUMBER() OVER (PARTITION BY ITEM_CODE ORDER BY creation_date DESC) as Seq
FROM ECOM_PRODUCT_IMAGES EPI
) EPI
INNER JOIN ECOM_POPULAR_PRODUCTS_MAPPING EPPIM ON EPPIM.ITEM_CODE = EPI.ITEM_CODE
INNER JOIN LOM_MST_PRODUCT LMP ON LMP.PROD_CODE = EPI.ITEM_CODE
INNER JOIN LOM_LNK_PROD_COMP LLPC ON LLPC.COLOC_PROD_CODE = LMP.PROD_CODE
WHERE EPI.Seq = 1 AND
EPPIM.ITEM_STATUS = 'ACTIVE';
EDIT 2: In that case you need to use GROUP BY clause with conditional aggregation
SELECT
EPI.ITEM_CODE, LMP.PROD_DESC, LLPC.COLOC_PROD_PRICE,
MAX(CASE WHEN EPI.Seq = 2
THEN (BASE_PATH + '' + EPI.IMAGE_FOLDER_NAME + '/' + EPI.IMAGE_DESCRIPTION)
END) AS POPULAR_PRODUCTS_IMAGE_PATHS,
MAX(CASE WHEN EPI.Seq = 1
THEN (BASE_PATH + '' + EPI.IMAGE_FOLDER_NAME + '/' + EPI.IMAGE_DESCRIPTION)
END) AS PATH_NEW
FROM (SELECT *,
ROW_NUMBER() OVER (PARTITION BY ITEM_CODE ORDER BY creation_date DESC) as Seq
FROM ECOM_PRODUCT_IMAGES EPI
) EPI
INNER JOIN ECOM_POPULAR_PRODUCTS_MAPPING EPPIM ON EPPIM.ITEM_CODE = EPI.ITEM_CODE
INNER JOIN LOM_MST_PRODUCT LMP ON LMP.PROD_CODE = EPI.ITEM_CODE
INNER JOIN LOM_LNK_PROD_COMP LLPC ON LLPC.COLOC_PROD_CODE = LMP.PROD_CODE
WHERE EPPIM.ITEM_STATUS = 'ACTIVE'
GROUP BY EPI.ITEM_CODE, LMP.PROD_DESC, LLPC.COLOC_PROD_PRICE;

here is my approach, also using a window function.
sample data
if object_id('tempdb..#x') is not null drop table #x
CREATE TABLE #x (ITEM_CODE VARCHAR(10), PROD_DESC VARCHAR(20),
COLOR_PROD_PRICE DECIMAL, POPULAR_PRODUCTS_IMAGE_PATHS VARCHAR(200))
INSERT INTO #X(ITEM_CODE,PROD_DESC,COLOR_PROD_PRICE,POPULAR_PRODUCTS_IMAGE_PATHS) VALUES
('P0001', 'Axe Brand', 88.000, 'some_path_to_img1.jpg'),
('P0001', 'Axe Brand', 88.000, 'some_path_to_img2.jpg'),
('P0002', 'Almond Nuts', 499.000, 'some_path_to_img1.jpg'),
('P0002', 'Almond Nuts', 499.000, 'some_path_to_img2.jpg')
query - just change #x to your table and it should work
;WITH my_cte as
(
SELECT *,
ROW_NUMBER() OVER(PARTITION BY ITEM_CODE ORDER BY POPULAR_PRODUCTS_IMAGE_PATHS) AS 'track_row'
FROM #x
)
SELECT a.ITEM_CODE, a.PROD_DESC, a.COLOR_PROD_PRICE,
a.POPULAR_PRODUCTS_IMAGE_PATHS + ' ' + b.POPULAR_PRODUCTS_IMAGE_PATHS AS 'POPULAR_PRODUCTS_IMAGE_PATHS'
FROM my_cte AS a
INNER JOIN
my_cte AS b ON a.ITEM_CODE=b.ITEM_CODE
WHERE a.track_row=1 AND b.track_row=2
output
ITEM_CODE PROD_DESC COLOR_PROD_PRICE POPULAR_PRODUCTS_IMAGE_PATHS
P0001 Axe Brand 88 some_path_to_img1.jpg some_path_to_img2.jpg
P0002 Almond Nuts 499 some_path_to_img1.jpg some_path_to_img2.jpg
