# List of window functions in YQL

The syntax for calling window functions is detailed in a
[separate article](../syntax/window.md).

## Aggregate functions {#aggregate-functions}

All the [aggregate functions](aggregation.md) can also be used as window functions.
In this case, each row includes an aggregation result obtained on a set of rows from
the [window frame](../syntax/window.md#frame).

## SOME {#some}

Get the value for an expression specified as an argument, for one of the table rows.
Gives no guarantee of which row is used. It's similar to the
[any()](https://clickhouse.tech/docs/en/sql-reference/aggregate-functions/reference/any/)
function in ClickHouse.

{% note alert %}

If one of the compared arguments is 0.0, the function always returns false.

{% endnote %}

```yql
SELECT 1;
```

End.
