Issues with merging two queries in the table configuration

#1

we created a table and trying to merge two queries for populating values in the table by using inner join command . but the innerjoin command not working with the present version of influxdb 1.5.1.
can you help me we what will be the equivalent command in the influxdb version 1.5.1.
Query1:
SELECT last(“a.used”) as a ,last(“b.used”) as b,last(“c.used”) as c FROM “JOLOKIA” where component !=’’ GROUP BY “host”,“component”
Query2:
SELECT last(“usage_idle”)* -1 + 100 as CPU_Usage FROM cpu where component != ''GROUP BY “host”

By using InnerJoin command
SELECT last(“a.used”) as a ,last(“b.used”) as b,last(“c.used”) as c FROM “JOLOKIA”, last(“usage_idle”)* -1 + 100 as CPU_Usage FROM “cpu” inner join CPU_Usage where component !=’’
GROUP BY “host”,“component”

When we try to run the above query , its throwing error.

Can you tell me why this happening.
