Oracle Wrap使用方法

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;
