# Update and remove properties safely

Update node properties using `SET` and remove properties by setting them to `NULL`.

## Usage

Use `SET` to update or add properties. To remove a property, set it to `NULL`. Note that FalkorDB does not support the `REMOVE` keyword.

## Example

```bash
redis-cli GRAPH.QUERY social "MATCH (u:User {id: 42})
SET u.email = 'dana@example.com', u.temp = NULL"
```

## Notes

- `SET` can update existing properties or add new ones
- Setting a property to `NULL` effectively removes it
- FalkorDB does not support the `REMOVE` keyword - use `NULL` instead
- Multiple property operations can be chained in a single `SET` clause
