Truncating a LONG column to fit a PL/SQL LONG var

Hi. What are the best practices for truncating a LONG column to fit a PL/SQL LONG variable?

I have a trigger that reads data from a LONG column and inserts it into a shadow table LONG column. It is not possible to read the above ~32K fields into the PL/SQL variable. I'm OK if I just truncate the LONG column so it fits. Is this possible?

Thanks,

Morten
