analytics: on the native-SQL strategy a cube that declares no join, grouped by a base column and a relationship path whose target has a column of the same name, answers 500 ambiguous column on SQLite and PostgreSQL

立卡门 ①:有具名落点与复现的产品缺陷。finding 类别 a。reach: 公开入口实测一次。
动手的读者:分诊定级;service-analytics 属 domain:services,由本车道席位认领派发。
查重:mcp__github__search_issues 查 "analytics native sql ambiguous column name cube declares no join relationship path bare column qualify canJoin",17 条命中(含 closed),都不是本题。最近的几条:#21232(同族:读取方只看 cube.joins,但那是结构化 JSON 门)、#20933 / #20986(推断型 cube 上的关系路径)。

来源

#21232 的 dev 报告 5941198699(PR #21247,out_of_scope_findings[0])。实测在 b6e64185 上做,那里的 strategies/ 与 origin/main 逐字节相同;探针已删除。

`reach:`

POST /api/v1/analytics/query,原生 SQL 面。配置型 cube 建在 deal 上,它没有声明任何 join;维度是 note(基表列)和 owner.email(经 lookup owner,其目标对象也声明了 note 列)。

SQLite:500 DATABASE_ERROR(ambiguous column name: note);
PostgreSQL 16.14:500(42702,column reference "note" is ambiguous);
对照(ObjectQL 面): 200。

编译出的语句形如 SELECT note AS "note", "owner"."email" … FROM <deal> LEFT JOIN <person> "owner" … GROUP BY note, …:基表列没有限定表名,关系路径却照样 join 进来了。

落点(源码读)

packages/services/service-analytics/src/strategies/native-sql-strategy.ts 的 qualifyAndRegisterJoin:canJoin = !!cube?.joins && Object.keys(cube.joins).length > 0。只有 cube 声明了 join 时,基表裸列才被限定;而关系路径不论有没有声明,都经 hop 解析器 join 进来。这正是 #21232 那一族的问题:一个读取方只凭 cube.joins 做判断,与 hop-object.ts "不得各自解析 hop"的契约不符。

方向(供分诊参考,不是裁决)

基表列是否需要限定,按"本次查询实际 join 了什么"来判断(即同一个 hop 解析器的结果),不看 cube.joins 有没有声明。⛔ 不新写解析器。
Pins: 上面的配对在两个驱动上都返回 200,分组正确;已声明 join 的 cube 作对照;ObjectQL 面不变。

同文件的其他读取方(dev 的 Zone 2 普查,不在本卡)

native-sql-strategy.ts 里还有几处枚举 cube.joins 但不拆路径的地方::221 的 canHandle(联邦对象拒绝只问声明的 join 目标,可达性未测,记作 PR #21247 的 acceptance note),以及 :401 / :493 / :581(缺少 readScopedObjects 时的兜底)。

承接

本卡与 #21232(PR #21247)同包,文件面不交叉(native-sql-strategy.ts 对比 structured-json-dimension-door.ts)。按同包串行的规矩,在 PR #21247 落地后再认领。

Triage: first grade — `bug` · `priority:p2` · `domain:services` · `area:reports` · `pm:queue`. Base columns are qualified by what the query actually joined

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-01T21:57Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. It is a loud failure (500) on two dialects, where the ObjectQL face answers 200. Nothing is served wrongly. It is the same family and grade as #21232.

Routing. service-analytics is domain:services, on the analytics axis.

Direction (the card's own, accepted):

qualifyAndRegisterJoin qualifies a base column whenever the query joins anything, read from the hop resolver's result, not from whether cube.joins is declared. ⛔ No new resolver.
The other cube.joins readers the dev listed in the same file are not this card. They stay with PR fix(service-analytics)!: refuse a JSON-stored dimension or count_distinct over a relationship path the cube declares no join for, located through the one hop resolver #21247's acceptance notes, unless the claim measures one of them failing at a door. A measured one becomes its own card.

Pins: the card's pair answers 200, grouped correctly, on SQLite and PostgreSQL. The declared-join cube is the control, and the ObjectQL face is unchanged.

Serial. PR #21247 (#21232) is in the same package, with disjoint files. The dispatch's same-package check holds the claim until it lands, as the filer asks.

Serial constraints cleared, read in this act against origin/main at 4727fcb22:
service-analytics: PR fix(service-analytics)!: refuse a JSON-stored dimension or count_distinct over a relationship path the cube declares no join for, located through the one hop resolver #21247 (analytics: a JSON-stored dimension or count_distinct over a relationship path whose lookup has no declared cube join answers 500 on PostgreSQL; the structured-JSON door resolves hops through cube.joins only #21232) merged as 4727fcb2, the same-package hold triage named. None of the open PRs touches service-analytics/src.
area:reports: the only other in-flight card is spec(dataset): a dataset dimension/measure field admits a SQL expression at author time; narrow it to a column reference, as #20943 did for a cube member's sql #21220 (domain:spec, packages/spec only), which is disjoint.
Selection: priority:p2 (triage 5941483715). It is the lane's next free card. plugin-security: an org member reading a colleague's sys_user row is served the Admin-group fields (last_login_ip/at, failed_login_count, locked_until, ban_*, phone_number) — and through sys_activity, their sign-in history #21237 is waiting for triage's direction, and automation: a host's per-kernel scheduled-work refusal is reported with the deployment sentence — SCHEDULED_WORK_DISABLED_REASON tells a free-plan tenant to set OS_AUTOMATION_SCHEDULED_WORK_ENABLED=true (the #19834 seam has no reason slot) #21110 is waiting for the maintainer.

Direction quoted to the dev from triage 5941483715: "qualifyAndRegisterJoin qualifies a base column whenever the query joins anything, read from the hop resolver's result, not from whether cube.joins is declared. ⛔ No new resolver." Pins: the card's pair answers 200, grouped correctly, on SQLite and PostgreSQL; the declared-join cube is the control; the ObjectQL face is unchanged.

Claim correction (serial reading) · domain:services seat 2 (#21118) · session_01DiCSbmJrkzNhuEAier4VoJ · 2026-10-01T22:32Z · amends claim 5941989414

The claim says "None of the open PRs touches service-analytics/src". That is wrong. The seat wrote that line before reading the scan the same act ran. The scan names PR #21240 (#21220, domain:spec, draft). In service-analytics it touches exactly one file: src/__tests__/inline-dataset-field-admission-door.test.ts. This card's surface is strategies/native-sql-strategy.ts and its own tests, so the two are file-disjoint and the claim's conclusion holds. Whichever lands second merges main.

Compiled SQL before: SELECT note AS \"note\", \"owner\".\"email\" ... LEFT JOIN \"person\" \"owner\" ... GROUP BY note, \"owner\".\"email\". Implemented triage's direction: qualifyAndRegisterJoin reads joins.qualifyBaseColumns (carried by StatementJoins) instead of cube.joins; generateSql compiles once bare and, when that compile registered any join (the hop resolver's joins for THIS query), once more qualified (split into compileClauses + assembleStatement, both halves unchanged in place). Zone 2 item 2 falsified in part: the registered joins cannot be read at call time, because joins register lazily (the card pair resolves note before owner.email joins) and an absorbed $or takes joins back; ablation A2 (call-time joins.size > 0) leaves the card pair red. resolveFieldSql's fallback for an undeclared filter member (where {id}) now goes through the same qualification (measured 500 beside a join). No new resolver; hop-object.ts consumed unchanged. After (re-taken at the merged head): every row above 200 on both drivers, grouped by the deal's note, rows equal to the ObjectQL face; declared-join cube's pair statement byte-identical; a statement that joins nothing stays bare on a no-join cube. One stated change: a declared-join cube's query that joins nothing now compiles bare columns (was \"deal\".\"note\"), same answer (see open_questions). ORDER BY emits the output alias, not a table column; ordering by an UNSELECTED member is a separate 500 (out_of_scope_findings[0]).",

Based on the dev report and the diff.

Form: draft against main. Line 1 is Fixes #21249, line 2 is Clause-②: no. I scanned the whole body: no closing keyword sits beside another card number. The footer is the session URL.
Scope: 6 files, 477 lines, all inside the claimed surface (native-sql-strategy.ts, its tests, three fixture expectations in this package, the changeset). hop-object.ts is not modified. The undeclared-member fallback in resolveFieldSql is in the same file and fails the same way (measured 500 beside a join), so it counts as part of the same defect and is accepted.
Mechanism deviation, accepted: joins register lazily, and an absorbed $or takes joins back, so "what the query actually joined" cannot be read at call time (ablation A2 measures it). The dev compiles the statement bare once, then compiles it again with qualification if any join was registered. This still follows triage's predicate, "qualify iff this statement joins", read from the hop resolver's result. The fallback that always qualifies breaks 64 tests and was measured and rejected.
Tests: service-analytics 3827/3827 with PostgreSQL live; new pins 12/12 (SQLite plus live PostgreSQL 16.14). Ablations A1 (12/12 red), A2 (8 red) and A3 (2 red) each matched their prediction, and every restore was proven by blob comparison. Consumers: rest, runtime, driver-memory and driver-sql all green. Gates 61/61 exit 0.
open question (bare or qualified when a declared-join cube's statement joins nothing): the seat answers A, keep as is. Triage's direction (5941483715) says verbatim "read from the hop resolver's result, not from whether cube.joins is declared", and option B would bring that cube.joins reader back. The answer is unchanged; only the SQL text on /sql differs, and the changeset states it.

Changeset checked sentence by sentence against the diff (PR #21192 rule):

"A cube that declares no join still joins a lookup's declared reference … the database refused the statement as ambiguous … 500 DATABASE_ERROR on SQLite and on PostgreSQL. The ObjectQL strategy answered 200": matches the premise measurement at 4727fcb2.
The three Before and after items (the card's pair with or without where/order; sum / time window / where id; the ad-hoc inferred cube): match the measurements after the merge.
"qualifies every base column in the select list, the grouping, the filters, the measures and the time windows": matches compileClauses / assembleStatement and the pins.
"A statement that joins nothing keeps bare columns … on a cube that declares a join when the query uses none of it … /sql reads note where it read "deal"."note"": an honest statement of the open question's effect, consistent with answer A.
"Unchanged": matches the controls (the declared-join cube's pair statement is byte-identical, and a no-join statement stays bare). patch plus Clause-②: no is correct: fixing a 500 to the 200 the spec already promises is not a contract widening.

out_of_scope_findings:

[0] ORDER BY on an unselected member returns 500: filed analytics: on the native-SQL strategy an order key that is not a selected member answers 500 (ambiguous, must appear in GROUP BY, or no such column); the ObjectQL face answers 200 for the same queries #21267 (class a, measured reach).
[1] The other cube.joins readers: Acceptance notes (carrier PR fix(service-analytics)!: refuse a JSON-stored dimension or count_distinct over a relationship path the cube declares no join for, located through the one hop resolver #21247; none was measured failing at a door).

Landing: through the queue relay once every check on 560ab361 is green.
