WHERE employee_id = 9999;
An error is thrown and there is no exception section in this procedure or the calling procedure,
therefore all transactions are rolled back.
Note: If the exception is not handled in the called procedure, the control is transferred to the
exception-handling section of the calling procedure. If the exception is handled, all the statements remain intact. If the
exception is not handled in the calling procedure’s exception-handling section, all the statements
are rolled back, and the exception propagates to the calling environment.
