The question

In Scotland Premier League, which away team won the most during the 2010 season?

the hint the set supplies: Final result should return the Team.team_long_name; Scotland Premier League refers to League.name = 'Scotland Premier League'; away team refers to away_team_api_id; away team that won the most refers to MAX(SUBTRACT(away_team_goal, home_team_goal) > 0); 2010 season refers to season = '2009/2010'; won the most refers to MAX(COUNT(*));

This question was audited without a prediction beside it, so there is nothing to compare the gold with. The probes below read the gold alone.

The statements

gold

SELECT teamInfo.team_long_name FROM League AS leagueData INNER JOIN Match AS matchData ON leagueData.id = matchData.league_id INNER JOIN Team AS teamInfo ON matchData.away_team_api_id = teamInfo.team_api_id WHERE leagueData.name = 'Scotland Premier League' AND matchData.season = '2009/2010' AND matchData.away_team_goal - matchData.home_team_goal > 0 GROUP BY teamInfo.team_long_name, matchData.away_team_api_id ORDER BY COUNT(*) DESC LIMIT 1

The probes

A smell is a mechanical reason to read this gold statement again. It is a heuristic: it does not state that the statement is wrong, and a maintainer decides.

ordering-over-numeric-text not applicable

this statement orders by a text column holding only numbers, and ordering it as a number gives a different answer, so the gold may be sorting 9.5 above 10

no ORDER BY key resolves to a text column

what it measured

  "heuristic": true,
  "reason": "no ORDER BY key resolves to a text column",
  "keys": [
    {
      "key": "count(*)",
      "not_applicable": "the key is an expression and not a column"
    }
  ]
}

arbitrary-cut fired

this statement cuts its result at a LIMIT that does not decide which rows come back, so a different but equally correct statement can return other rows and score zero
