@.TABLE_NAME VARCHAR(60),
@.COLUMN_NAME VARCHAR(60),
@.COLUMN_TYPE VARCHAR(60),
@.COLUMN_SIZE INT(10)
AS
BEGIN
IF EXISTS (SELECT @.COLUMN_NAME FROM syscolumns)
BEGIN
ALTER TABLE @.TABLE_NAME ALTER @.COLUMN_NAME + ' ' + @.COLUMN_TYPE+'('+ @.COLUMN_SIZE +')'

ALTER TABLE @.TABLE_NAME ADD @.COLUMN_NAME + ' ' + @.COLUMN_TYPE+'('+ @.COLUMN_SIZE +')'
END
END

CREATE PROCEDURE ENCRYPTION getString()

AS
SELECT * FORM CUSTOMER

-

Funtion getString() return a string is " With Encryption"?

Do I call function getString() in here ?

You need to use dynamic sql for this.

Code Snippet

IF EXISTS(SELECT NAME FROM SYSOBJECTS WHERE NAME ='MODISTRCTTABLE ' AND TYPE='P')
BEGIN
DROP PROCEDURE MODISTRUCT_TABLE
END
GO

CREATE PROCEDURE MODISTRUCT_TABLE
@.TABLE_NAME VARCHAR(60),
@.COLUMN_NAME VARCHAR(60),
@.COLUMN_TYPE VARCHAR(60),
@.COLUMN_SIZE INT(10)
AS
BEGIN
IF EXISTS (SELECT @.COLUMN_NAME FROM syscolumns)
BEGIN
exec ('ALTER TABLE '+@.TABLE_NAME+' ALTER '+@.COLUMN_NAME + ' ' + @.COLUMN_TYPE+'('+ @.COLUMN_SIZE +')' )
END
ELSE
BEGIN
exec('ALTER TABLE '+@.TABLE_NAME+' ADD '+@.COLUMN_NAME + ' ' + @.COLUMN_TYPE+'('+ @.COLUMN_SIZE +')' )
END
END

The other proc is also incorrect. It should be like so.

Code Snippet

CREATE PROCEDURE getString()
with ENCRYPTION
AS
SELECT * FROM CUSTOMER

|||Thanks Oj my idea is not clearly ! I have a Store procedure :
--
Create procedure MyEnCryption With Encryption
AS
Begin
Select * from Customer
End

I want replace string " With Encryption" with calling Function GetString(); Function GetString() return a string is "With Encryption"

this store rewrite :
-
Create procedure MyEnCryption GetString()
AS
Begin
Select * from Customer
End

--

Is this store run ?|||

What you're trying to do is not possible. The syntax to create a procedure is like so:

CREATE PROC [ EDURE ] procedure_name [ ; number ]
[ { @.parameter data_type }
[ VARYING ] [ = default ] [ OUTPUT ]
] [ ,...n ]

[ WITH
{ RECOMPILE | ENCRYPTION | RECOMPILE , ENCRYPTION } ]

[ FOR REPLICATION ]

AS sql_statement [ ...n ]

While creating the objects you have to use the proper syntax what is already defined..

You can achive your desired output if you create your object using dynamic SQL...

But it is not recommanded to do this.. & I didn’t understand why you need this logic..

Note:

When you encrypt the procedure/function/view/trigger you have to store your soruce code on filesystem or source safe for future reference, you never get back the soruce text from the SQL Server. So, it is really bad idea to have dynamic sql to create encrypted objects.

Code Snippet

Declare @.sql as varchar(8000)

Set @.sql = 'Create procedure MyEnCryption ' +GetString() + '

AS

Begin

Select * from Customer

End'

exec (@.sql)
