SELECT T1.Name as Name1, T2.Name as Name2, T3.Name as Name3 FROM Test T1,Test T2, Test T3 WHERE T1.ID=1 AND T2.ID=2 AND T3.ID=3

Sorry, I haven't looked at the whole thread. My assumption is that Naomi expects the table to look like this:
CREATE TABLE Test (ID int, Name C(20))
INSERT INTO Test (Id,Name) VALUES(1,"Tom")
INSERT INTO Test (Id,Name) VALUES (2,"Dick")
INSERT INTO Test (Id,Name) VALUES (3,"Harry")
