SQL 函数存储过程视图加密及解密

-- 加密存储过程
CREATE PROCEDURE MTB_WithEncryption WITH ENCRYPTION
AS
BEGIN
-- START: Properitary Business Logic
--
--
--
--
-- END: Properitary Business Logic
SELECT * FROM dbo.Table_1
SELECT 'From ENCRYPTED Stored Procedure'
END
GO

-- 常规存储过程
CREATE PROCEDURE MTB_NoEncryption
AS
BEGIN
SELECT 'From MTB_NoEncryption'
END
GO

-- 函数

CREATE FUNCTION MTB_fnNoEncryption
(
@value varchar(50)
)
RETURNS varchar(50)
AS
BEGIN

RETURN @value + ' - From Regular Function'

END
GO

-- 加密函数

CREATE FUNCTION MTB_fnWithEncryption
(
@value varchar(50)
)
RETURNS varchar(50) WITH ENCRYPTION
AS
BEGIN
-- START: Properitary Business Logic
--
--
--
--
-- END: Properitary Business Logic
RETURN @value + ' - From ENCRYPTED Function'

END
GO
