Right now, the meaning of each %s is fixed, and determined by the order in the query. From the code: d_NoIdQuery=getArg("basic-query”); d_IdQuery=getArg("id-query"); … if(domain_id < 0) { query = (boost::format(d_NoIdQuery) % sqlEscape(qtype.getName()) % sqlEscape(lcqname) ).str(); } else { query = (boost::format(d_IdQuery) % sqlEscape(qtype.getName()) % sqlEscape(lcqname) % domain_id ).str(); } This applies type and lcqname (the lowercased query name) to the %s items in the query, in that order. You cannot change this without editing gsqlbackend.cc and recompiling, right now. Note that -if- PowerDNS has a domain_id, it will use d_IdQuery (which you know as id-query), as also seen in the code above. So for your situation, changing id-query may be enough.
