因项目管理规定，所有的存储程式（SP）都需要加密。
如何批量加密所有的SP呢？
在网上找到了参考的代码，然后发现除SP外连同View,Trigger,Function等也可以一并处理！

如下是在原作基础上略作补充的方法：
sql
create procedure sp_EncryptObject
(
@Object sysname='All'
)
as
/*
当@Object=All的时候，对所有的函数，存储过程，视图和触发器进行加密
调用方法：
1. Execute sp_EncryptObject 'All'
2. Execute sp_EncryptObject 'ObjectName'
*/
begin
set nocount on
if @Object <>'All'
begin
if not exists(select 1 from sys.objects a where a.object_id=object_id(@Object) And a.type in('P','V','TR','FN','IF','TF'))
begin
--SQL Server 2008
--raiserror 50001 N'无效的加密对象！加密对象必须是函数，存储过程，视图或触发器。'
--SQL Server 2012
--throw 50001, N'无效的加密对象！加密对象必须是函数，存储过程，视图或触发器。',1
--SQL Server 2016
raiserror ('无效的加密对象！加密对象必须是函数，存储过程，视图或触发器。',16,1)
return
end
if exists(select 1 from sys.sql_modules a where a.object_id=object_id(@Object) and a.definition is null)
begin
--SQL Server 2008

--SQL Server 2016
raiserror ('无效的加密对象！加密对象必须是函数，存储过程，视图或触发器。',16,1)
return
end
end

go2022.08.22补充：
亲测存在的bug
- create proc 转换成 alter proc 时会检查中间的空格，所以不一定能加密成功
2.数据库中存在_back命名的程式会被识别成备份还原，所以跑完会覆盖原有程式（此处风险极大）
