Question

I have two columns (both primary) [PLAYER_ID] [LEAUGE_ID]

something like this:

Player_id      League_id
2139            8
2153            8
2302            10
2441            8
2441            10  
2441            16   

I am trying to find the same player who played only in leages 8 and 10, so although 2441 played for 16, we need to omit that.

According to the table above, I am trying to only find:

Player_id     League_id_1     League_id_2
2441          8               10

Thanks in advance!

Answer 1

Try

select t1.player_id, t1.league_id league_id_1, t2.league_id league_id_2
  from table1 t1
  join table1 t2 on t1.player_id = t2.player_id
 where t1.league_id = 8
   and t2.league_id = 10
