How do I pass more than one attribute with sqlcounter

Hello world !!!

I want to limit the transferred volume of data for my hotspot users to 5GB.
In counter.conf I have :

sqlcounter volumecounter{
        counter-name = Max-All-Octets
        check-name = Mikrotik-Total-Limit
        reply-name = Mikrotik-Xmit-Limit
        sqlmod-inst = sql
        key = User-Name
        reset = never
        query = "select ifnull(sum(acctinputoctets),0) from radacct WHERE UserName='%{%k}'"
}

This only conpares to Mikrotik-Total-Limit and returns only Mikrotik-Xmit-Limit. What do I need to do
to get the return values for the related Gigawords values ?
Is it possible to get both values from one counter or do I need a second one?

I have seen that the problem was often discussed here, the answers were always “use …-Gigawords”, but
no one had a solution how to implement it.

Any hints ?

TIA
