Hi Giulio,
SelectQuery is replaced with ObjectSelect. But in your case (a query modeled in
the DataMap), you would actually use something else - a MappedSelect query per
https://cayenne.apache.org/docs/4.2/cayenne-guide/#mappedselect-and-mappedexec
MappedSelect.query("attachment", Attachment.class)
.param("reference", aReference)
.param("user", anUser)
.select(context);
Thanks,
Andrus
