Specify different date formats for multiple sources in ETL

artywah

I am combining a number of data sources with date columns using an ETL before performing other calculations on them.

 

Some of the sources have Australian date format (DD/MM/YYYY), and others have US format (MM/DD/YYYY).

 

The ETL gives me results in YYYY-MM-DD format, where it's actually incorrectly converted some of the dates to YYYY-DD-MM by assuming the wrong input date format. This means I end up with results from the future (eg 2018-12-03).

 

What's the best way to ensure the ETL always knows the correct input date format?

Hi. @artywah

 

Is it possible to avoid by replacing the date that is incorrectly converted by using regex?

 

Set Column Type
  Column   : DateColumn
  Data Type: Text

　Pattern A　YYYY-MM-DD (TEXT)

    Set Column Type
      Column   : DateColumn
      Data Type: Date
      Format   : Year first


　Pattern B  YYYY-DD-MM (TEXT)

　　Replace Text
　　　Column            : DateColumn
      Search "Use Regex": ^([0-9]*)-([0-9]*)-([0-9]*)
      Replace           :  $1-$3-$2

    Set Column Type
      Column   : DateColumn
      Data Type: Date
      Format   : Year first

Unfortnately this isn't working. It seems Domo is being too smart and processing the format before I can do anything with it in an ETL.

 

It seems I need to set the date format as Domo imports the data (before I can perform an ETL on it)
