I am supposed to

List the names of members in the artist group called 'Today'

What I have tried:

I have tried all of these but none give me the answer so I don't know if I'm using the join wrong or if it is something else.

select members.FirstName AS MembFirst, xrefartistsmembers.ArtistID AS ArtID from members JOIN xrefartistsmembers ON members.MemberID=xrefartistsmembers.ArtistID;

select members.FirstName AS MembFirst, xrefartistsmembers.ArtistID AS ArtID from members JOIN xrefartistsmembers ON xrefartistsmembers.ArtistID = xrefartistsmembers.MemberID;

select members.FirstName AS MembFirst, artists.ArtistID AS ArtID from members JOIN artists ON members.MemberID=artists.ArtistID;

Try this

SQL

SELECT M.FirstName, M.LastName
FROM Members                   As M
    Join xrefartistsmembers    As X On X.MemberId = M.MemberId
    Join Artists               As A On A.ArtistId = X.ArtistId
WHERE A.ArtistName = 'Today'

-- Instead of 'ArtistName' if you already know 'ArtistId' below should be fine

SELECT FirstName, LastName
FROM Members                   As M
    Join xrefartistsmembers    As X On X.MemberId=M.MemberId
WHERE X.ArtistId = 16

In the sample data you've provided, there's no data for 'Today'.

So, to get some realistic data with the data you provided, below query may give you more clarity

SQL

SELECT M.FirstName, M.LastName
FROM Members                   As M
    Join xrefartistsmembers    As X On X.MemberId = M.MemberId
    Join Artists               As A On A.ArtistId = X.ArtistId
WHERE A.ArtistName = 'Confused'

-- Epected output would be as below

FirstName  LastName
---------- -----------
Doug       Finney
Terry      Irving
Michelle   Henderson

Solution 1

You did not join all the tables required to perform the query

SQL

SELECT M.FirstName, M.LastName FROM artists A
  INNER JOIN xrefartistsmembers X ON X.ArtistID = A.ArtistId
  INNER JOIN members M ON M.MemberID = X.MemberID
WHERE A.ArtistName = 'Today'
