I have this database schema on a Oracle 12c database :
I'm trying to answer this question :
What is the game in which Dallas Mavericks had the biggest percentage of successful 3-point shots ?
I've managed to answer this question with this query:
SELECT HOME_TEAMS.TEAM_NAME "HOME TEAM", AWAY_TEAMS.TEAM_NAME "AWAY TEAM", GAMES.GAME_DATE "DATE", TEAMS.TEAM_ID "GENERIC ID", HOME_TEAMS.TEAM_ID "HOME_ID", AWAY_TEAMS.TEAM_ID "AWAY_ID", GAME_STATISTICS.X3POINTSHOTS_PERCENTAGE "3 POINTS PERCENTAGE" FROM GAMES_TEAMS_STATISTICS INNER JOIN GAMES ON GAMES_TEAMS_STATISTICS.GAME_ID = GAMES.GAME_ID INNER JOIN TEAMS ON GAMES_TEAMS_STATISTICS.TEAM_ID = TEAMS.TEAM_ID INNER JOIN TEAMS HOME_TEAMS ON GAMES.HOME_TEAM = HOME_TEAMS.TEAM_ID INNER JOIN TEAMS AWAY_TEAMS ON GAMES.AWAY_TEAM = AWAY_TEAMS.TEAM_ID INNER JOIN GAME_STATISTICS ON GAMES_TEAMS_STATISTICS.STATS_ID = GAME_STATISTICS.STATS_ID WHERE TEAMS.TEAM_ACRONYM = 'DAL' ORDER BY GAME_STATISTICS.X3POINTSHOTS_PERCENTAGE DESC FETCH FIRST 1 ROWS WITH TIES;
However, to answer this question , I join the teams table 3 times. Is there any way I can write this query in a more efficient way , avoiding so many joins ?
