# rollup()

<Icon icon="tag" iconType="duotone" /> Since [1.0.0][toolkit-1.0.0]

Combine multiple intermediate `uddsketch` aggregates, produced by `uddsketch`, into a single intermediate `uddsketch`

## Arguments

The syntax is:

```sql theme={"dark"}
rollup(
  sketch UddSketch
) RETURNS UddSketch
```
