Your SQL statement is dynamic (column name at run-time). You have to use
routines from a predefined package (DBMS_SQL) that properly managed dynamic
statements and also DDL statements. Your update will be split into some
phases (preparing, parsing and executing) each one accomplished by a
procedure/function in the package.
I don't know if there are limitations in the use of this package inside a
trigger but I don't think so.
See the manual for more precise information on the DBMS_SQL package.
