I am trying to get comma-separated values from the following 3 tables:
Teams: Id
Players: Id, Name
TeamsPlayers: Id, TeamId, PlayerId
What I am trying to get is a result like this:
TeamId | PlayerNames |
---|---|
1 | Ronaldo,Rivaldo,Ronaldinho,Dida |
2 | Riquelme,Messi,Aguero,DiMaria |
sql
SELECT STRING_AGG(Name, ',')
FROM (
SELECT tp.TeamId, p.Name
FROM Players p
JOIN TeamPlayers tp ON p.Id = tp.PlayerId
GROUP BY tp.TeamId, p.Name
)
Expanding on Larnu's comment.
Asssuming your initial query has the proper elements
SELECT tp.TeamId,
,Names = STRING_AGG(p.Name, ',')
FROM Players p
JOIN TeamPlayers tp ON p.Id = tp.PlayerId
GROUP BY tp.TeamId
