Is it possible to use updatemulti and set a field in a table to another?

IE I have a table with 4 fields: pk, f1,f2,f3.

I want to do something like Update table set f1 = f2, f3 = "ABC" Where...

Is this possible with update multi or will I have to loop through a collection and do it manually?

Thanks!

You can do that. Please see for an example: Using the generated code / Field expressions and aggregates -> Expressions in entity updates in the documentation. It has an example of updating a field directly with an expression. Your situation is simpler, but should use the same approach: use an expression to set the value of the field.

Thanks! Worked great.
