Oracle--使用Wrap工具 加密你的SQL
使用 Oracle Wrap工具加密你的代码
Oracle提供Wrap工具,可以用于加密你的Package等.
不过需要注意的是,加密后的代码无法解密,你需要保管好你的源代码。
以下是个例子:
  1.源代码
  create or replace function get_rowid
  (l_rowid in varchar2)
  return varchar2
  is
  ls_my_rowid     varchar2(200);          
  rowid_type      number;          
  object_number   number;          
  relative_fno    number;          
  block_number    number;          
  row_number      number;  
  begin
  dbms_rowid.rowid_info(l_rowid,rowid_type,object_number,relative_fno, block_number, row_number);         
  ls_my_rowid := 'Object# is      :'||to_char(object_number)||chr(10)||
  'Relative_fno is :'||to_char(relative_fno)||chr(10)||
  'Block number is :'||to_char(block_number)||chr(10)||
  'Row number is   :'||to_char(row_number);
  return ls_my_rowid ;
  end;          
  /                     



  2.代码功能测试
