The mutating table message shows that you are trying to query a table value
which is/may be currently being modified, in this case the :old value. It
*may* work if you referred to the :new value - I forget the exact
conditions for mutation and I'm almost surprised that you are getting a
mutation problem... unless entry_id is being updated?
As far as I can see, your code should look something like:
BEGIN
SELECT descrip2
INTO :new.descrip1
FROM table2
WHERE (table2.entry_id = :new.entry_id)
;
END;
