q900001 GOLD-ONLY, sandbox demo

The question

What was spent in each category, amount by amount?

the hint the set supplies: the amounts spent refers to the spent column of every row of the category

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 category, group_concat(spent) FROM spend GROUP BY category ORDER BY category ASC

category: ascending

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 quiet

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

what it measured

{
  "heuristic": true,
  "keys": [
    {
      "key": "category",
      "column": "spend.category",
      "declared_type": "TEXT",
      "not_applicable": null,

      },
      "every_value_is_numeric": false
    }
  ]
}

arbitrary-cut not applicable

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

the statement states no LIMIT

what it measured

{
  "heuristic": true,
  "reason": "the statement states no LIMIT"
}

not-a-function-of-the-data fired

rerun over the same rows in another physical order this statement gives another answer, so its result depends on how the rows are stored and not only on the data

duplicate-full-row quiet

this statement returns the same whole row more than once and never says DISTINCT, so a statement answering the same question once per row disagrees on multiplicity alone
