It rewrites query contains at least two aggregate functions from [sum](../../sql-reference/aggregate-functions/reference/sum.md#agg_function-sum), [count](../../sql-reference/aggregate-functions/reference/count.md#agg_function-count) or [avg](../../sql-reference/aggregate-functions/reference/avg.md#agg_function-avg) with identical argument to [sumCount](../../sql-reference/aggregate-functions/reference/sumcount.md#agg_function-sumCount).

Позволяет объединить агрегатные функции с одинаковым аргументом. Запрос, содержащий по крайней мере две агрегатные функции: [sum](../../sql-reference/aggregate-functions/reference/sum.md#agg_function-sum), [count](../../sql-reference/aggregate-functions/reference/count.md#agg_function-count) или [avg](../../sql-reference/aggregate-functions/reference/avg.md#agg_function-avg) с одинаковым аргументом, перезаписывается как [sumCount](../../sql-reference/aggregate-functions/reference/sumcount.md#agg_function-sumCount).
