q1380 EQUAL

The question

What is the total amount of money spent for food?

the hint the set supplies: total amount of money spent refers to SUM(spent); spent for food refers to category = 'Food'

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

The two statements name their result columns differently. A projection is compared by position and declared type, so these names did not decide the verdict. They are part of the canonical rendering each result is hashed under, so the two result hashes differ with them.

gold: sum
prediction: total_spent_for_food

The statements

gold

SELECT SUM(spent) FROM budget WHERE category = 'Food'

this statement states no ordering of its own

sha256:abaa01a4ef80cd27d53cb3b55b4ba1df448a0d110ec3b5e034976199556be8a0

second

SELECT SUM(spent) AS total_spent_for_food
FROM budget
WHERE category = 'Food'

this statement states no ordering of its own

sha256:f57cd3b3bb57ad80b2f9c9b9b9b0ac9de007f798021b0dc8165d9c77b9bd477c

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

no rows

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: 1
gold_distinct_rows: 1
second_distinct_rows: 1

the test-suite check: 1

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

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"
}

float-aggregate-order fired

this statement aggregates floating point numbers, so its last digits depend on the order the rows were summed in; the values agree to six significant digits
