Question

I want to create a query that selects the columns PlayerName , PlayerNumber, Location, PartnerName, PartnerNumber, Location from the following tables:

• Players (Columns: Id, PlayerName, PlayerNumber, LocationId)
• Partners (Columns: Id, PartnerName, PartnerNumber, LocationId)
• Locations (Columns: Id, Location)

But I cannot figure out how to do that. Does anyone have any ideas?

Answer 1

Find the updated query after considering registration table.

SELECT players.playername, 
       player.playernumber, 
       L1.location, 
       partners.partnername, 
       partners.partnernumber, 
       L2.location 
FROM   registration R 
       INNER JOIN players 
               ON players.id = R.playerid 
       INNER JOIN partners 
               ON partners.id = R.partnerid 
       INNER JOIN locations L1 
               ON players.locationid = L1.id 
       INNER JOIN locations L2 
               ON partners.locationid = L2.id
