The exception section begins with the EXCEPTION keyword and contains exception handlers that define recovery actions for runtime errors. Each exception handler consists of a WHEN clause specifying an exception name. Exception handling is mandatory in PL/SQL blocks. Predefined exceptions like NO_DATA_FOUND are declared in the declaration section while non-predefined exceptions require declaring the exception name first before handling. The RAISE_APPLICATION_ERROR procedure can be used to return user-defined error messages.
