Please set according local indices where tmsesqlquery.indexlocal[n].fields[0] is the sortfield. If sorting should be based on a lookup value a field of FieldKind fkLookup must be used. Do *not* activate LookupCache, set a local index on the keyfield in lookup-dataset so directdata-access can be used. IIRC sorting of lookup fields is supported in git master version only.
