I need to do a join of 4 separate tables to extract results.  How do I accomplish this?  Can this be done in a single ETL?

    Yes, you can join multiple tables in Magic ETL. This would involve joining one table at a time, using the "Join Data" transform 4 times in a row. You would progressively build up the final dataset by joining the tables one at a time.

     

    Alternatively, this is also possible using a DataFlow and doing a JOIN or LEFT JOIN in SQL. Feel free to post a more specific use-case/problem description with any other questions.

    Do I connect my subsequent joins to the Join action or the Output action?

    OK.  Don't get pissy.  I don't know your Domo rules.  If there are customs to be used when engaging the community spell them out somewhere!  Why is everyone so afraid of actually providing documentation on software anymore!
