Question

I have 2 tables event + event_artist

event

eventId | eventName   ------------------- 1 , gig1   2, gig2     

event_artist

eventId, artistName  -------------------  1, Led Zip   1, The Beatles   

ie Led Zep and the Beatles are both playing @ Gig1

I need to create the SQl to bind to a gridview ( you necessarily need to know about gridviews to answers this )

The results that i want would look like this
eventId = 1, EventName = Gig1. ArtistLineup = Led Zep, The beatles

So i need to create an alias ArtistLineup that would list all the artist. Via an inner select i think.

Any thoughts on what this would look like.

Answer 1

Saw this in SQL Server Magazine- not great, and the total list will have an upper length limit, but:

drop table event go  drop table event_artist go  create table event (eventid int, eventname varchar(255)) go  create table event_artist (eventid int, artistname varchar(255)) go  insert into event values (1, 'gig1') go  insert into event values (2, 'gig2') go  insert into event_artist values (1, 'Led Zip') go  insert into event_artist values (1, 'The Beatles') go  drop function Event_Display go  create function Event_Display (@EventID int) returns varchar(2000) as begin     declare @artistList varchar(2000)     set @artistList=''      select @artistList=@artistList + ', ' + isnull(artistname,'')      from event_artist      where eventid=@EventID      return substring(@artistList,3,2000)  --eliminate initial comma end go  select event.eventid, event.eventname, dbo.Event_Display(event.eventid) from event  

                                                                                                                                                                                                                                                    1           gig1        Led Zip, The Beatles  2           gig2
