So, if I had two tables with ID numbers as the joining column but every ID was consistent across both (e.g. marketing data and ad data, with 30 IDs each and all IDs are the same), it wouldn't matter which join I did, would it? As there are no IDs in the marketing data that don't also exist in the ad data). Is that correct?
I swear to god I've been listening to my lecturer explain this for 2 hours, and in 1 min you explained how to join them.
Super clear. The best explanation of joins. Thank you.
Glad it was helpful!
Excellent explanation, keep it up!!
Thanks a lot!
Thanks a lot, Henry. This video is very helpful.
Unfortunately sound level is very low. Sorry for that. All other OK. Great.
