PL/SQL打包工具wrap:

dbms_ddl包中有一个打包函数wrap和打包过程create_wrapped，把源代码转换成十六进制进行隐藏。

wrap：打包函数，输入源码后，返回打包好的PL/SQL源代码；

create_wrapped：打包过程，对输入的源码进行打包；

要查看打包后的源代码，可通过视图 user_source进行查看

desc user_source;

Column Datatype NULL Description

OWNER VARCHAR2(30) NOT NULL Owner of the object

NAME VARCHAR2(30) NOT NULL Name of the object

TYPE VARCHAR2(12) Type of object: FUNCTION, JAVA SOURCE, PACKAGE, PACKAGE BODY, PROCEDURE, TRIGGER, TYPE, TYPE BODY

LINE NUMBER NOT NULL Line number of this line of source

TEXT VARCHAR2(4000) Text source of the stored object

示例：

declare

v_procedure varchar2(32767);

begin

v_procedure := 'create or replace procedure wrap_test is '

||' rec airport_list%rowtype; '

||' cursor airport_cur is select * from airport_list; '

||' begin '

||' for rec in cursor loop '

||' dbms_output.put_line(rec.airport_code); '

||' end loop; '

||' end; ';

sys.dbms_ddl.create_wrapped(v_procedure);

execute immediate dbms_ddl.wrap(v_procedure);

end;
