The SQL I've tried is:
select commcost.maplot, commcost.unitno from commcost
where not exists(select 1 from commcost, bldg
where commcost.maplot = bldg.maplot and
commcost.unitno = bldg.unitno)
order by commcost.maplot
change it to:
select commcost.maplot, commcost.unitno from commcost
where not exists(select 1 from bldg
where commcost.maplot = bldg.maplot and
commcost.unitno = bldg.unitno)
order by commcost.maplot
or simply write:
select * from commcost except select * from bldg;
