Encryption/Decryption all the row data

Hi all,
With the following i am able to encrypt/decrypt only columns which are varbinary.I am not able to encrypt the integer/numeric values.
To protect the one row,i have to encrypt each column in the row.Which results reducing the performace in realtime.CREATE
MASTER KEY ENCRYPTION BY PASSWORD='LORD'CREATE
CERTIFICATE ENCDECTEST WITH SUBJECT='LORD' CREATE SYMMETRIC KEY TESTKEY WITH ALGORITHM=TRIPLE_DES
ENCRYPTION
BY CERTIFICATE ENCDECTEST-- Create a Sample TableCREATE TABLE USERS (UID INT IDENTITY(100,1),UFNAME VARCHAR(100),ULNAME VARCHAR(100),ULOGINDI VARCHAR(50),UPASSWORD VARBINARY(256))
-- Create a Procedure to Insert Data in TableCREATE PROC [InsertUSER] @UFNAME
VARCHAR(100), @ULNAME VARCHAR(100), @ULOGINDI
VARCHAR(12), @UPASSWORD
VARCHAR(20)AS
BEGINOPEN SYMMETRIC KEY TESTKEY
DECRYPTION BY CERTIFICATE ENCDECTEST;
INSERT INTO [USERS](UFNAME, ULNAME, ULOGINDI, UPASSWORD)
VALUES
(@UFNAME, @ULNAME, @ULOGINDI,EncryptByKey(Key_GUID('TESTKEY'), @UPASSWORD));
END;EXEC INSERTUSER 'Koti','Routhu','Koti_J_Routhu','GloryToLORD'
-- Procedure to Retrive UsersCREATE PROC [RetrieveUSER] @UID INT
AS
BEGINOPEN SYMMETRIC KEY TESTKEY
DECRYPTION BY CERTIFICATE ENCDECTEST; SELECT UID, UFNAME, ULNAME, ULOGINDI, CONVERT(VARCHAR(20),DECRYPTBYKEY(UPASSWORD)) AS PASSWORD
FROM USERS WHERE UID = @UID;END
; EXEC
RetrieveUSER 100
Is there any way to encrypt all the rowdata as one column adding with delimiters, and data stored in the all columns in encrypted format
and when decrypt the row, resulted data should be populated as columns of that row.
Thank You,
