Putting Current day and Previous day as columns instead of rows
Hello!
I have run into a problem just like this link:
I followed the sql transform but once I ran it the output dataset was the same as the input dataset. I don't know what I am doing wrong, I even uploaded a file that is exact to the example in the link above.
If someone can help me figure out why it seems like its not working for me?
Thanks!

@DANIH your final output should be SELECT * FROM transform2, not from the original input dataset. Not sure if that was just a typo, but your transform SQL looks correct that leads up to the final output.

1st transform:
SELECT
`Date`
,SUM(`Sales`) As 'Sales'
,`Product`
FROM `domo_test_csv`
GROUP BY `Date`, `Product`
2nd Transform:
SELECT
a.`Date`
,a.`Sales` AS 'Current_Day'
,b.`Sales` As 'Previous_Day'
,a.`Product`
FROM `domo_test_csv` a
LEFT JOIN `domo_test_csv` b
ON a.`Date` = DATE_ADD(b.`Date`, INTERVAL 1 DAY)
AND a.`Product` = b.
Product
output data set:
SELECT * FROM `domo_test_csv`
