# ALTER VIEW

`ALTER VIEW` changes the definition of a [view](https://ydb.tech/docs/en/yql/reference/syntax/concepts/datamodel/view.md?version=v25.4).

{% note warning %}

This feature is not supported yet.

{% endnote %}

Instead, you can redefine a view by dropping it and recreating it with a different query or options:

```yql
DROP VIEW redefined_view;
CREATE VIEW redefined_view ...;
```

Please note that the two statements are executed separately, unlike a single `ALTER VIEW` statement. If a view is recreated in this way, it might be possible to observe the view in a deleted state for a brief moment.
