Group Sales Data by Hour by Day

DANIH

Hi!

I have a dataset that has a timestamp as the date column. I need to sum the sales by hour for each day. I need this done in Magic ETL so I can do another part of my problem before putting it into a card. Is there a way to do this? I have been playing with 'Group By' tile and 'Rank & Window' tile but can't seem to figure it out.

Here is a easier sample of what I want:

Any tips would be appreciated!

Hi @DANIH

You can use a formula tile to calculate the hour by converting your timestamp to a date (defaults to a time of 00:00:00) and then adding the number of hours in the timestamp.

DATE(`dt`) + INTERVAL HOUR(`dt`) HOUR

You'd group by the new timestamp field and SUM / aggregate your Sales column

Alternatively you can truncate a timestamp to a part of the timestamp like hour with the TRUNC function:

TRUNC(`dt`, 'HOUR')

@GrantSmith I'm trying both of those options. So would I then do a group by tile to group by sales with the new timestamp column?
