Question: Could you tell me what’s wrong in this phrase:

"In this database, there are failed copies of the file."

Is it grammatically correct to write "In this database" at the beggining of a sentence?

Thank you.

Answer: 
You can keep the original-

* In this database there are failed copies of the file.

In this database, there are failed copies of the file.

I think it's fine. Maybe you can drop that comma if you decide to say: "There are failed copies of the file in this database." Otherwise, I believe it's grammatically correct.
