To rename a view in a database, you can use the `ALTER VIEW` statement in SQL. Here is an example of how you can rename a view called `old_view` to `new_view`:
```sql ALTER VIEW old_view RENAME TO new_view; ```
This statement will change the name of the view from `old_view` to `new_view`. Make sure to replace `old_view` and `new_view` with the actual names of the views you want to rename.
