inequality join condition

Hello everyone,

I'm quite new to clickhouse and recenlty I got stuck on a join condition and need a workaround.

I have two tables:
TimeSlots(Start datetime, End datetime)
Deliveries(DeliveryId, ...., StatusTimestamp, ....)

I need to granularize a query for the number of deliveries for the the preset periods.

SELECT slots.Start, Count(DeliveryId)
FROM Deliveries AS Dlr
inner JOIN TimeSlots AS slots
ON Dlr.StatusTimestamp > slots.Start AND Dlr.StatusTimestamp < slots.End
GROUP BY slots.Start

Aparently, the inequality join conditions are not supported.

Any ideas for workaround?

Thanks in advance
