I have an ASP.Net webpage where the user selects a row for editing. I want to use the row lock on that row and once the user finishes the editing and updates another user can edit that row i.e. How can I use rowlock so that only one user can edit a row?
Thank you
You can’t lock a row like that using DB engine locks.
Most other strategies would rely on keeping the connection open (such as sp_getapplock) and this is nonsensical in web apps.
Even if you set a flag on the row, what happens if the user simply closes the browser mid-edit?
I’d suggest using a timestamp/rowversion column to detect changes to the row in other sessions.
