R-ORD GOLD-ONLY arbitrary-cut

financial · dev_20251106-00000-of-00001 from https://huggingface.co/datasets/birdsql/bird_sql_dev_20251106/resolve/3c11fb193e5439b338e23677fa0aae11e8b85db9/data/dev_20251106-00000-of-00001.json (commit 3c11fb19, downloaded 2026-09-07)

The question

List out the account numbers of female clients who are oldest and has lowest average salary, calculate the gap between this lowest average salary with the highest average salary?

the hint the set supplies: Female means gender = 'F'; A11 refers to average salary; Gap = highest average salary - lowest average salary; If the person A's birthdate > B's birthdate, it means that person B is order than person A.

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 T1.account_id,
       (SELECT MAX(A11) - MIN(A11) FROM district)
FROM account AS T1
INNER JOIN district AS T2 ON T1.district_id = T2.district_id
INNER JOIN disp AS T3 ON T1.account_id = T3.account_id
INNER JOIN client AS T4 ON T3.client_id = T4.client_id
WHERE T2.district_id = (
  SELECT district_id FROM client WHERE gender = 'F' ORDER BY birth_date ASC LIMIT 1
)
ORDER BY T2.A11 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": "T2.A11",

      "declared_type": "INTEGER",
      "not_applicable": "the column is not declared as text"
    }
  ]
}

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
