Performance of view (as a table alias) over a table

Using a view to encapsula开发者_Python百科te a table whose name changes yearly (tablename_year) called "vw_Tablename_Current" so I don't have to change any procs that use the table to reflect the new table name, just the view.

This is temporary until I'm able to make deeper model changes. Is there any performance hit on wrapping a single table in a view like this?

You can use a synonym as well which is cleaner

   CREATE SYNONYM tablename FOR tablename_year;

No, there is no performance difference if the view is essentially a SELECT * FROM table
