Should the answer here be null?
Hi Essien!
Thanks for reaching out.
Could you please explain your question with more details? What do you mean by NULL? There should be some result set.
Looking forward to your answer.

Hi everyone!
I hope you don't mind if I join the conversation.

Yes, sometimes refreshing/getting back the database to its initial state may solve our issues. Other times, carefully following the state of the relevant tables may still take us to a solution!
Hope this helps but please feel free to get back to us should you need further assistance. Thank you.
Kind regards,
