Wtf did i do wrong this time adding row not working

At first I was inserting into wrong table but now I don’t know.

Did you try asking this to ChatGPT ? You may find answer quicker.

I remember back in 2004; I was struggling with DB and needed to check big oracle book for answers for each problem as that time Google and SO were not so popular or didn’t have enough info to support.

The last command looks okay but it is hard to tell 100% because it is an image and images are hard to read.
Try to reset, and make sure you are connected to the database and hopefully it will work the second time.
