Answer for Confusion: SQL Tableau Problem 1

Hi Ji Hu!

Thanks for reaching out.

There’s nothing you have omitted and you are right in your intuition. Actually, thank you very much for pointing this out. We were thinking a lot about how to start the SQL-Tableau challenges and finally opted for a task and solution that are not inherently incorrect but are in a sense more loose in the understanding of the problem. 

It is actually the ‘active’ column in Task 2 that will, I think, answer your question. However, we thought that it would be too much to do in terms of steps to do in SQL as a first task, so we left that for Task 2.

Thank you for the understanding in advance and, once again, thank you for pointing this out. 

Please feel free to write back if needed. Currently, I will mark this lesson for a revision. 

Best,
Martin
