A data engineer is working with two tables. Each of these tables is displayed below in its entirety.
The data engineer runs the following query to join these tables together:
Which of the following will be returned by the above query?
Option B is the way to go. These types of join questions are like the crossword puzzles of the data engineering world - you just need to keep a cool head and follow the logic.
Hmm, looks like a straightforward join to me. Option B seems like the obvious choice here. Although, I do wonder if the data engineer is caffeinated enough to spot the right answer.
