Accessing ORA_ROWSCN in the triggers body

Question

Is it possible to access ORA_ROWSCN pseudo-column in the body of BEFORE triggers? I'm thinking about storing this value in the table itself to emulate SQLServer rowversion behaviour.

Answer 1

It doesn't seem to be possible (even if Oracle itself populates the value before launching BEFORE UPDATE trigger) - referring to :NEW.ora_rowscn in the trigger body generates error, select ora_rowscn from table1 in the trigger causes mutating trigger error.
