Token function in CQL for composite partition key

[Ajay]

Hi,

I have a column family as below:

(Wide row design)
CREATE TABLE clicks (hour text,adId int,itemId int,time timeuuid,PRIMARY
KEY((adId, hour), time, itemId)) WITH CLUSTERING ORDER BY (time DESC);

Now to query for a given Ad Id and specific 3 hours say 2015-01-07 11 to
2015-01-07 14, how do I use the token function in the CQL.

Thanks
Ajay
