Re: For frequently changing table name and column name?..!!

Why don't you just (re-)create a View that 'maps' the new/different Table and Columns names into the 'standard' ones used by the application?

Example:

Create View STANDARD_NAME
As
Select NEW_COLUMN1 As STANDARD_COLUMN1,

        NEW_COLUMN2 As STANDARD_COLUMN2,
        NEW_COLUMN3 As STANDARD_COLUMN3
