access max.date from sql table
Hi. I have two input datasets in SQL Magic Transformation. One table called daily
the other one estimated
. Both tables have the same columns. I need to fetch the data from estimated
table but only for the date that is later than max(`Date`)
in table dail
Data looks like this. Table daily
Date Name Revenue 2021-08-01 A 10 2021-08-01 B 20 2021-08-02 A 4 2021-08-02 B 5
Table estimated
Date Name Revenue 2021-08-02 A 4 2021-08-02 B 4 2021-08-03 A 30 2021-08-03 B 35
The desired output is:
Date Name Revenue 2021-08-03 A 30 2021-08-03 B 35
I would normally create a temporarily table where I would store the max Date like `WITH TABLE as (select max.Date from daily` but this functionality is not supported in domo.
I tried union both tables and create a new column last_date
where for estimated table portion I assigned everything to NULL and daily
portion fetched the max.Date but it didn't return any data.
Thanks for help in advance.

This should do it:
SELECT 'date', 'Name', 'Revenue'
FROM 'estimated'
WHERE 'date' > (SELECT MAX('date') FROM 'daily')

if you can't write SQL, i strongly recommend you learn your way around Magic 2.0. The more SQL you write, the fewer people at your org can support you as your queries become more complex.
If it were me, i would
1) Trans_Table = union all my data together with a column for 'Activity Type'
2) Date_DimByType = calculate the Max Date and Min Date Group By Activity Type.
3) JOIN tables together by Activity Type.
use Analyzer to construct my actuals vs. expected using
sum(CASE When Activity type ... ).
This construction avoids filtering data in ETL, forces you to think in dimensional modeling terms, and introduces recycle-able data models that can be extended. https://www.youtube.com/watch?v=PVbOeLSae9o&t=252s
