Clever. It will work, and it will do what the OP wanted. But it is not a clean solution. this would not work if you did want to be able to set some fields to NULL Right. And this is a good reason not to use this feature. A second good reason to avoid this idiom is that it makes debugging more difficult. If all updates look the same, it will be harder to spot the offending one in a log file whan you're hunting for bugs. A further good reason not to go for this solution is that you are straining the DBMS to encourage the programmer's laziness, and I am not talking of the Laziness that makes good coders. It isn't difficult to create a query using only the fields that are needed. Why looking for trouble? In reply to Re: Re: How to get a placeholder to keep the current column value?
