Also is there any view where I can see statements like create or drop schema object. In v$sqlarea I cannot see this type of DDL. I can see alter schema object.

It is 8.1.7 Solaris

As to the question - I did not try it but if owner of the trigger has access to$sqlarea you can inside trigger query v$sqlarea for current session and check if there are any alter... drop statements. Strange that oracle does not provide SQL statement as one of the trigger attributs.

I've written a system event trigger which records information on when a table was dropped or truncated. I would also like to record when someone does an "alter table drop column..." The problem is determining when the alter statement includes the drop column clause. It looks like I have to use the ora_is_drop_column function, calling it for each column in the table and checking the return code. Is there a way of determing whether "drop column" was issued without using this function?
