Question

I have been trying to find something about this topic and I can\'t seem to find anything, there were a few questions on here but they didn\'t work for my particular project.

Answer 1

Recently I had to make quite more extended version of datatable. Although it is based on my own schema, but it maybe useful for someone (it is based on previous a'r answer):

  SELECT
    team_id                                             team_id,
    t.name                                              team_name,
    t.country                                           country,
    count(*)                                            matches,
    SUM(scored)                                         scored_total,
    SUM(conceided)                                      conceided_total,
    count(CASE WHEN scored > conceided
      THEN 1 END)                                       wins,
    count(CASE WHEN scored = conceided
      THEN 1 END)                                       draws,
    count(CASE WHEN scored < conceided
      THEN 1 END)                                       lost,
    sum(scored) - sum(conceided)                        balance,
    sum(
        CASE WHEN scored > conceided
          THEN 3
        ELSE 0 END
        + CASE WHEN scored = conceided
          THEN 1
          ELSE 0 END)                                   points,
    count(CASE WHEN place = 'home'
      THEN 1 END)                                       home_matches,
    count(CASE WHEN place = 'home' AND scored > conceided
      THEN 1 END)                                       home_wins,
    count(CASE WHEN place = 'home' AND scored = conceided
      THEN 1 END)                                       home_draws,
    count(CASE WHEN place = 'home' AND scored < conceided
