Hi All..
I am trying to parameterize a tablename in a StoredProcedure something like below and use the below code in my other Stored procedure..

CREATE PROCEDURE SP_BACKUPTABLE @TABLENAME VARCHAR(255)
AS
DECLARE @BACKUPTABLE VARCHAR(255)
DECLARE @ALIASTABLE VARCHAR(255)
SET @BACKUPTABLE = @TABLENAME + '_BK'
SET @ALIASTABLE = @TABLENAME + '_ALIAS'
SELECT @ALIASTABLE.* FROM @TABLENAME AS @ALIASTABLE

i get error 'near .'...
How do i achieve the above code-functionality

Thanks in advance

You'll have to use dynamic sql to achieve this - i.e. construct a SQL string and then execute it. Lookup "Dynamic SQL" in BOL for the specifics.

If you need to really send table name as parameter, use dynamic sql as suggested
Refer www.sommarskog.se/dynamic_sql.html
