Hi,
In my database I have 3 columns ie., Id,Name,Subject(Marks).I inserted records as 1,Sai, 20.
When I am trying to insert new marks to the Sai ,it won't accept new marks to the Sai.
That means I want to restrict to re-enter the marks for particular record and it allows only one time to enter marks..
How to write code for this.. ??

instead of update
as
begin
Print 'You can not re-enter the marks'
end
