In addition:

Ora_ SQL _txt is supported by 9i, so how can I obtain the SQL statement through event trigger in 8i?

Quote:

SQL> Create or replace trigger snapshot_too_old

Declare
Rochelle SQL _text ora_name_list_t;

Trigger dropped.

After searching, both ora_ SQL _txt and 9i documents are supported;
In 8i, how does one obtain the SQL statement that triggers the trigger in event trigger?
