Re: ora-04091, updating same table in trigger

Upon further reflection, you are correct.
I should have stated a slight difference. I have INSTEAD_OF triggers on views, which need to commit data in several tables (and in a few cases, against other views - UGLY), which in turn have triggers on them as well. The regular 'table' triggers don't have the commits, but the view triggers do.
