[Quoted] Hi everybody.
[Quoted] I've been working for a just a while now with Oracle (or with any DB for that matter. I'm really new to all this), and I've encountered a problem I [Quoted] can't find a solution to.
I've created a table... let's call it "STUDENTS". It has a Primary Key field [Quoted] (St_ID) and a bunch of other fields. It also has a Foreign Key (Tut_ID), an [Quoted] [Quoted] dientification for his Tutor, a reference to the TUTORS table. The thing is, [Quoted] [Quoted] a student MAY or MAY NOT have a tutor, so the Foreign Key field Tutor MAY or [Quoted] MAY NOT have data; id est, it May have an ID number, or else it will be NULL. [Quoted] [Quoted] Now, here's where I'm having the problem. When I do a simple:
SELECT * FROM STUDENTS,TUTORS
WHERE STUDENTS.Tut_ID=TUTORS.Tut_ID;
[Quoted] [Quoted] it shows me only those rows WITH something on the Tut_ID field... and I was [Quoted] [Quoted] hoping (and need) to list every row ond STUDENTS, adding the Tutor data when [Quoted] [Quoted] [Quoted] it's present, ommiting it (empty fields) when is not...
[Quoted] Maybe there is an obvious way to do this, just a simple instruction... but I'm reourceless on this.
[Quoted] Pleasy. Any help would be enourmosly appreciated. thanks!
