So you update a field by not changing its value, to execute a piece of code that has nothing to do with the field and the value :-) >Is there an easy way to duplicate this, or should I work around it?

Then you can do: UPDATE mytable SET dummy = 1 - dummy WHERE ... to execute the piece of code that responds to an update of 'dummy'.
