> The following SQL does not compile:
> {code:title=invalid_having_hop_start_sql}
> SELECT
> c AS k,
> COUNT(a) AS v,
> HOP_START(rowtime, INTERVAL '1' MINUTE, INTERVAL '1' MINUTE) AS
> windowStart,
> HOP_END(rowtime, INTERVAL '1' MINUTE, INTERVAL '1' MINUTE) AS windowEnd
> FROM
> T1
> GROUP BY

> c
> HAVING
> SUM(b) > 1
