ms access - sql query return the rows without common attributes -


i'm new sql ans ms-access. so, have table tab1, columns id, decscription, number want make query returns id of rows without common description , number. desirable output this

i have tried

select  id tab1 group  id, description, number having count(*)=1; 

but returns logical error.

if want return rows unique, can do:

select * tab1 not exists (select 1                   tab1 t                   tab1.description = t.description , tab1.number = t.number ,                         tab1.id <> t.id                  ); 

you can using aggregation. id:

select max(id) tab1 group description, number having min(id) = max(id);
