Assessment/Exercise data already exist in MySQL DB/Table

I have observed in last few Assessment/Exercises that whatever the ask is that data/rows/tables are found already present. It limits me from practising the exercise, and sometimes it also leads to wrong result and hence failure in exercise. Please see attached image for Assessment Question SQL Insert (#17 in SQL Tutorial) showing someone has already created emp name ‘Sam’ but with wrong date, so even though I have created correct emp name ‘Sam’ with correct date, still when clicking Submit Answer System finds wrong record and hence my answer does not stand valid.

This might be due to same DB user/password used by someone else at the same time.

Can you please look into it and help resolve the problem.

Thank you.

Yes, you are right. It might be already existing. You can delete and recreate it.
