Hi guys,
I am loading data from an SQL database. I have two columns: date and volume and in my SQL query I limit data to the last 8 weeks. Like this:
MyTable:
LOAD testdate, volume;
SELECT
CAST(timestamp AS DATE) as testdate
SUM(volume) as volume,
FROM $(dbname).dbo.TestTable
WHERE timestamp >= DATEADD(week,-8, GETDATE())
GROUP BY CAST(timestamp AS DATE)
I now wish to create a new Qlik table where I have the following columns:
date || volume || volume same day last week || volume (8 week average)
The point is that I only wish to have rows for the last 7 days in my new table, but I need 8 weeks of data to calculate data for all rows in the new table. How would I go about calculating data for the last two columns?
I am new to Qlik and Im not sure about the syntax.
Thanks!
Best Regards,
Rasmus
