I have already searched for answer saying the inserted value could be long or mismatch of datatype, due to that this type of error could come but this web app works fine on my local system but when I use it after publishing it to the web, this error shows up but all other web page insert queries work just fine

Error shows up on only this one page.

This error suggests that the data you're trying to write is too big for one of the columns. It works locally but not in your production environment, which could be a few things. Is the schema the same on your local box as your production environment? Do you know what data is being written that causes the error?
