No, you don't have to query all columns, but you have to specify which columns are "optional"

@ObjectMapable
class MyModel {
   @Column("id")  // per default throwOnColumnIndexNotFound = true
    long id;

   @Column(value = "optionalName", throwOnColumnIndexNotFound = false)
    String optionalName;
}

Then an exception will be thrown if you try to query table without id column, but you can query table without optionalName
