Deleting a record from prodigy

I am getting an error in prodigy (Unterminated string starting at: line 1 column 65534 (char 65533) and I got to know this due to the long document text, so I wanted to delete the last record from the database. can I delete the last record from the database by using prodigy??

Are you using MySQL? If so, it's possible that you were hitting the problem described here: Unexpected character in found when decoding object value

Since this is likely a truncated entry in the database, going via Prodigy likely won't work because it won't be able to load the dataset (which is why you see the error here). So the best solution would be to just do it manually in your database – either with an SQL query, or by using a database browser.
