Hi Thanh,

You are right, Powershell display Null as blank. The shared results are just self-checking hints. Your code will be graded using an auto-grader that will run your queries on Powershell. So you don't need to worry about displaying NULLs as done in the shared file.

G'day, The query output (lab2) is a great deal to us. But there are NULL results are make me confused. Right now my Powershell only show NULL as blank = | | . But the images show the NULL as |NULL|. However, I think blank as NULL is good enough for this lab. But does it ? Do we need to open the option that show NULL as |NULL| in this lab and in the future? Thanks you.
