Question

Is it possible to prevent any changes to a row in sql?

Let’s say the record is created. But once it’s created I don’t want the record to be modified ever.

So the user can still try to do a update table set column = value .. but that would raise an error preventing it to be modified something like that.

Answer 1

yes you could do it with a trigger provided that the user doesn’t do something like this

alter table disable trigger
update table...

you can also deny update on that column like this (SQL Server 2005 and up syntax)

DENY UPDATE ON OBJECT::TableName(ColumnName) TO UserNAme;
