Hello! I have a question about Question 4 in the VR Startup Company exercise. The prompt is to list the names of projects that were not chosen by any employees. My code is:
I don’t understand why the code needs the “WHERE current_project IS NOT NULL” statement to run correctly. There are no null values for project_id, so why does it matter if null is included in the list of values that the project ids are being compared against? The code does not run at all without that statement.
I was also wondering if there is a log somewhere that I’m missing, that would really be helpful… Thanks for the help!
