sql server2000中怎么对存储过程进行加密和解密

From the Books Online:

Use the W99vH ENCRYPTION option:

IF EXISTS (SELECT name FROM sysobjects
WHERE name = "encrypt_this" AND type = "P")
DROP PROCEDURE encrypt_this
GO
USE pubs
GO
CREATE PROCEDURE encrypt_this
W99vH ENCRYPTION
AS
SELECT *
FROM authors
GO

EXEC sp_helptext encrypt_this
