Selecting two different Names using the same table with same field

Question

Hello,
I am trying to display several fields from different tables. Here are some of the fields that I need: The instructor needs to go after the social.
WESL | ENGR-1101-SW1 | Hinojosa | Ashley | Social | Instructor |
I am using a table where they have the social and I need to get both the student and the instructor. How do I select the instructor when the instructor's id is on a different table. example
CLASS PERSON CLASS_ASSIGN
student_id student_id: name facutly_id
Here is the code that I have so far and it works.
rem ----------------
rem Filename: cer.sql
rem Purpose: to get data from banner and put into flat file
rem Date: August 17, 2006 4:51 P.M.
rem Author: Robert Hernandez
rem ---------------
rem Notes: Need to add the Instructor - having problems
rem using the same spriden_id.
rem Also need to have admissions enter the grad date for
rem several students: Procedure is working as is.

Can you be more precise , please :
- which table stores the people identities ? (I call this one Identity)
- which table gives the class where the student works in (I cal l this one Claa_attendees)
- which table gives the instructor of a class (I call this one Class)
If your issue is that you have one table which stores Itendities , and you need to display Student identity and Instructor Identity, you have to call this table twice in your query , using table aliases . I mean :
Select Stud_iden.name, Instr_iden.name
From Identity Stud_iden, Identity Instr_iden, Class_attendees, Class
Where Class.clas_id = class_attendees.class_id
and class.instructor_id = Instr_iden.people_id
and class_attendees.student_id = Stud_iden.people_id
Is this what you need to do ?
