--BASE64编码
CREATE FUNCTION [dbo].[FnBase64Encode](@src varchar(max))
  RETURNS VARCHAR(max)
as
begin
  declare @bin varbinary(max)
  set @bin=Convert(varbinary(max), @src)
  return cast(N'' as xml).value('xs:base64Binary(xs:hexBinary(sql:variable("@bin")))', 'varchar(max)')
end
GO

 

--BASE64解码

CREATE FUNCTION [dbo].[FnBase64Decode](@64 varchar(max))
  RETURNs VARCHAR(max)
AS
BEGIN
  declare @bin varbinary(max)
  set @bin=cast(N'' as xml).value('xs:base64Binary(sql:variable("@64"))', 'varbinary(max)')
  return Convert(varchar(max),@bin)
END

-- 存储过程demo

ALTER PROCEDURE p_user_register (@name nvarchar(50),@username nvarchar(50), @password nvarchar(50),@msg nvarchar(255) OUTPUT)
AS
BEGIN
SELECT @msg=COUNT(*) FROM t_user u WHERE u.UserName = @username AND u.Password = @password;

IF @msg = '1' BEGIN
set @msg='username 重复,请重新注册'
END
ELSE BEGIN
INSERT INTO t_user (UserName,Password,name,roles,token)
VALUES(@username, @password,@name,'admin', dbo.FnBase64Encode(@username+@password+@name+convert(varchar(19),getdate(),120)) )
set @msg='注册成功'
END
END
