    Awesome video!!! I do mot of my stuff in excel, and am trying to build better database skills. Just curious, which platform are you making the database in?

      Airtable is the software I build all my databases in 👍

    Great explanation of a junction table. Airtable aside, though, I'm curious about the odd ghosting effect that's in all of them. Whenever your hands come into frame, this ghosting appears at the top of the frame, like the whole video has been overlaid on top of itself and mirrored vertically. Do you know why that's happening?

      Hey Justin, thanks for watching.
      I think we finally tackled the ghosting effect. Seems to have been a problem with my old camera - it has been replaced now and future videos aren't showing any signs.
      That, or my house is haunted by wandering hands that mirror mine...

    Is there a workaround for doing UNIONS in Airtable? I want to create a combine view of multiple linked tables from different bases in my workspace. All fields are same in the linked tables.

      not sure I understand the question - sorry!

      @@GarethPronovost Thanks for the reply. Actually, AirTable has since added a feature that will allow you to feed multiple source tables into a single synced table. This addresses my need perfectly.

    Could you please tell me what the exact formula to get rid of the Error message? Why doesn't just using Rates Link work? Thanks!

    • @GarethPronovost
      @GarethPronovost  5 років тому +1

      Totally - the error is caused by Airtable looking at the linked records and trying to multiple something to it. The linked record is not merely a number though - it's an entire record containing much more than just a currency amount. This causes the formula to break (as I accidentally showcased in the video, lol).
      The way to get around this is to first create a field that looks at the linked record field and outputs a number. The easiest way to do this is to build a field (let's call it "LINK"). This field is a formula type that is simply looking at the "Rates Link" - the output should be the value of the rates link linked record.
      Then, your calculation could look at the "LINK" field and multiply it by the hours worked. Hopes this makes sense!

      @@nicmamom - there are so many options, I'm not sure where to start. Some formulas might be:
      {Field 1} * {Field 2}
      {Field 1} - {Field 2}
      SWITCH ( {Field 1} , 'Yes' , 1 , 'No' , 2)

    Is it all about classic N:M relation using an extra table?

    • @GarethPronovost
      @GarethPronovost  4 роки тому +1

      I typically build 1:n relationships from the junction table, so Junction:Table 1 = 1:n and Junction:Table 2 - 1:n

    maonday.com or airtable? for business database and profit calculation (with many many variables, product items, customers and so on)?

      I haven't used Monday.com much, so I can't speak to it in detail. However, I use and consult in Airtable because it solves this problem beautifully. So while I can't say whether Monday can solve your specific needs, I can speak to Airtable and say that it's worth looking into! 💪
