And I, this.
In the article of interest at
http://www.oracle.com/technology/oramag/oracle/08-sep/o58asktom.html Tom explains that a package and 3 triggers can be used to avoid the problem that the developers created for themselves by the use of this trigger.
The problem is actually more fundamental than that.
The 3 triggers and a package solution (or compound trigger in 11g) is actually a crutch required to deal with a poorly designed database. I have in fact used that 'solution' to enforce logic in an intentionally poorly designed database as part of a presentation on normalization.
It's a nice trick to have have up your sleeve if dealing with a schema that cannot be changed, but is still a poor substitute for properly designed databases.
