q358 NOT_EQUAL, minidev-pg gpt-35-turbo-instruct

The question

What is the border color of card "Ancestor's Chosen"?

the hint the set supplies: name of card = 'Ancestor''s Chosen' ;

NOT_EQUAL states that these two statements disagree on this data under this rule. It does not state which of them is wrong.

read by hand, 2026-09-04: B harmless: one distinct row repeated; DISTINCT added by the prediction; a list under twice the answer with every row present

one distinct row (black) repeated, once per printing

a maintainer's reading of this question, out of classification.json, copied from plans/reports/prediction-mode-260904-real-predictions/classification.json. It is not a verdict and nothing above it was computed from it.

The statements

gold

SELECT DISTINCT borderColor FROM cards WHERE name = 'Ancestor''s Chosen'

this statement states no ordering of its own

sha256:bbb146afe803261bd361edae92568b4b4de432c43b9e27b110e3117fa12752e2

second

SELECT  bordercolor
FROM cards
WHERE name = 'Ancestor''s Chosen'

this statement states no ordering of its own

sha256:1a6e1835a73b9ffa20d8f6beb3df2ddb5c31bda24ce671e8480c8ac5159adec0

The marked tokens are where the two texts differ. Two statements that differ everywhere can return the same rows, and two that differ in one token can return other rows; the verdict above is read off the results.

The rows they differ in

in gold, not in the prediction, 0 rows

from counterexample.json, 0 rows, up to 25 shown per side

side	bordercolortext
no rows

in the prediction, not in gold, 3 rows

from counterexample.json, 3 rows, up to 25 shown per side, 1 on this page

side	times	bordercolortext
second	3	black

What the benchmark would have said

BIRD's own check: 1

set(second_rows) == set(gold_rows), float4/float8 cells as Python float as psycopg2 returns them, numeric as Decimal

https://github.com/bird-bench/mini_dev/blob/main/evaluation/evaluation_ex.py

gold_rows: 1
second_rows: 4
gold_distinct_rows: 1
second_distinct_rows: 1

the test-suite check: 0

result_eq: equal row counts and equal column counts, each row unordered as a quick rejection, then the two equal as a list when the gold text holds ORDER BY and as a multiset otherwise, under some permutation of the columns; DISTINCT is not stripped and re-executed, and the cells are PostgreSQL's as psycopg2 returns them

ruiqi-zhong/test-suite-sql-eval, exec_eval.py, result_eq, at commit 48cb78ec: https://github.com/ruiqi-zhong/test-suite-sql-eval/blob/48cb78ecf7f610620206283846c76751b18a1326/exec_eval.py

order_matters: false
gold_rows: 1
second_rows: 4
gold_columns: 1
second_columns: 1

the class: multiplicity

The class states what makes these two results unequal under this rule, read off the two results and nothing else. It does not state which of the two statements is wrong.

The gold returned 1 rows and the prediction 4. 1 rows occur in both results at least once.

gold_types: ["text"]
second_types: ["text"]
multiset_equal: false
set_equal: true
order_equal: false

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

the statement states no top level ORDER BY

what it measured

{
  "heuristic": true,
  "reason": "the statement states no top level ORDER BY"
}

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 quiet

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 not applicable

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
