SQLITE: merging rows into single row if they share a column

Question

From a previous post, I have the following view in sqlite3:

CREATE View AttendeeTableView AS

SELECT  (LastName || \" \" || FirstName) as AttendeeName,  
                


        

Answer 1

I'm thinking a inner select might help, like:

CREATE View AttendeeTableView AS

SELECT  (LastName || " " || FirstName) as AttendeeName,  

(
  select CompanyName
FROM    Attendee A_innner 
JOIN    CompanyAttendeeRelation CAR  /* is this where company name is? */  
ON      on CAR.AttendeeId = A.AttendeeId /* if not remove the joins and CAR */
WHERE   A_inner.last_name = A_outer.last_name and
        A_inner.first_name = A_outer.first_name
),
PhotoURI,
CAR.CompanyId,
CAR.AttendeeId 


FROM    Attendee A_outer 
JOIN    CompanyAttendeeRelation CAR_outer  
ON      on CAR_outer.AttendeeId = A_outer.AttendeeId 

GROUP by LastName,FirstName
ORDER BY LastName, FirstName;
