您可以使用set verify off关闭新旧值显示。希望下面的代码段有用。

SQL> SET VERIFY OFF;
SQL> set serveroutput on;
SQL> DECLARE
  2    inputData VARCHAR2(1024);
  3  BEGIN
  4    inputData :='&&inputData' ;
  5    Dbms_Output.put_line('Value entered is:' || inputData);
  6  END;
  7  /
Enter value for inputdata: test
Value entered is:test

PL/SQL procedure successfully completed.

SQL>

为什么新的和旧的值打印当Pl / Sql程序运行时。
