data.db will not be edited by that command (as opposed to that done by the -i switch of sed). You'll need to redirect the output of that command in a temporary file and then, rename that temporary file to data.db. Was the first occurrence of that pattern replaced by the replacement string in the terminal output?
It would help to post a representative sample of data.db. Also, mention the output produced by that command on this sample and the expected output.
Ah, I see
No way to see in terminal as data.db contents are too long
I redirected to a text file with this command:
The output test.txt file has exactly same contents as original data.db, binary matching. So, the patetrn was not replaced
