database - How to hide stored procedures and triggers code from users other than SYSDBA in Interbase?

Question

I found some information about the encryption and embedded password features in Interbase 2009, but it does not prevent database users to see the source code. Is it possible to hide the stored procedures and triggers codes from all user including SYSDBA too? If not at least I can hide it from some users.

Answer 1

想出了如何做到这一点：

update rdb$Triggers set rdb$Trigger_source = ""
where
    rdb$system_flag = 0
    and rdb$trigger_name not like "CHECK%";

update rdb$procedures set rdb$procedure_source="";

Answer 2

最后我听说它无法隐藏。但是，可以从系统表中删除过程的源代码。我忘记了这样做的细节，但这是长期以来一直有效的方法。
