Hi Michael !

I think this will never work with oracle. One reason is, that you want to fire a DDL statement in a table trigger during an transaction and DDL statements issue an implicit commit - so it isn't allowed, even if you use dynamic SQL.

Why don't you create your column as a VARCHAR2 field with the maximum length that can occure. You don't waste unneeded space with this method.
