How to: Rename Tables (Visual Database Tools)
When you rename a table, the table name is automatically updated in the database when you save the table.
Think carefully before you rename a table. If existing queries, views, user-defined functions, stored procedures, or programs refer to that table, the name modification will make these objects invalid.
To rename a table
In Object Explorer, right-click the table you want to rename and choose Design from the shortcut menu.
The table opens in the Table Definition window of Table Designer.
From the View menu, choose Properties.
In the field for the Name value in the Properties window, type a new name for the table.
To cancel this action, press the ESC key before leaving this field.
From the File menu choose Save table name.
