service-analytics: the native-SQL face still treats mssql as an unknown dialect for its window, boolean aggregand and refusal text #31626
Description
domain:server#2 · os-steve · session_01ADHkmQKZzp4DLtqiCkZZRM
Filing gate: ① measured gaps from a card's report. The #31394 os-dev-report (comment 6724726840 on #31394, PR #31625) names three as out of scope. Filed as ONE family card, since they share one cause. ⛔ Not a claim.
Reader: the domain:server seat that owns packages/services/service-analytics, from pm:queue once #31394 lands.
Dedupe (open AND closed): analytics mssql LIMIT, analytics mssql OFFSET FETCH, analytics mssql aggregand, service-analytics mssql → #31394, #31395, #31327, #21595, #20446 only. None covers these constructs.
Blocked-by: #31394
reach: dashboards whose native-SQL statement runs against a federated SQL Server object (#31327). The dev's reading is compile-level. Measure first whether the native-SQL face is selected for such a datasource; if it never is, this card closes.
class: b · type: Bug
Grade: p3, self-graded by the server seat, same as #31394 (Ruling-ref: 「定级你可以自己决定」).
维护者速读
#31394 让仪表盘的原生 SQL 在 SQL Server 上按正确规则做文本匹配。同一条路径上还有三处仍把 SQL Server 当作「未知数据库」：分页写成 SQL Server 不认的 LIMIT，布尔（bit）列求和没按 SQL Server 的写法，拒绝提示说 mssql「未知」。这三处同一个原因，一张卡一起修。
What is wrong (read by the #31394 dev at 833400e0, compile level)
- Window:
native-sql-strategy.tsends a statement withLIMIT n, and withOFFSET_ONLY_LIMIT_SQL'sunknowncell (LIMIT 9223372036854775807) for an offset-only window. SQL Server parses neither; it takesOFFSET … ROWS FETCH NEXT … ROWS ONLYafter anORDER BY. - Boolean aggregand:
aggregandDialectOfmaps mssql tounknown, soSUMover abitcolumn is not cast the way driver-sql'smssqlAggregandOperandSqlcasts it. - Refusal text: the read-scope membership / empty refusal says the dialect "is not known" for mssql, which service-analytics: the native-SQL face emits plain LIKE for mssql, so a dashboard's text filter on a SQL Server federated object does not keep #6518's case-exact / case-folded contract the driver keeps #31394 makes a known dialect.
Expected
- Each construct emits SQL Server's own spelling, reusing driver-sql's constructs through
@objectstack/corethe way service-analytics: the native-SQL face emits plain LIKE for mssql, so a dashboard's text filter on a SQL Server federated object does not keep #6518's case-exact / case-folded contract the driver keeps #31394 did for text match (no third hand copy). - Pins red on main first, compile-level for each arm, plus a live cell when
OS_TEST_MSSQL_URLis present. CONTROL: sqlite / postgres / mysql output unchanged.

Thread-read: 6730603257
Premise: to be measured first. Step 0 measures whether the native-SQL face is ever selected for a federated SQL Server datasource. If it never is, the card goes back to the seat and closes as unreachable, with no code change (triage 6724993342 endorses this).
Narrowing: no. CONTROL: sqlite, postgres and mysql output is byte-identical.
Serial constraints cleared: seat 2's #31589 adds AI tools in service-analytics, not in the native-SQL strategy, so the surfaces are disjoint.

Measured on objectstack-ai/objectstack main 0105a687 with a throwaway vitest file (deleted, tree clean) that composes the REAL AnalyticsServicePlugin over a real ObjectQL engine and a real SqlDriver on knex client mssql (schemaMode external, datasource erp, dialectName mssql; knex never reaches a server, so each query fails at connect after the face is chosen). EXECUTION: for a federated SQL Server object in the shape every in-repo producer writes (object.external present; external-datasource-service.ts writes it on import), the native-SQL face is NEVER selected: the plugin wires isExternalObject = (engine.getObject(name).external != null) at plugin.ts:1506 and NativeSQLStrategy.canHandle declines it (ADR-0062 D6, native-sql-strategy.ts:670-679); the engine call recorded was aggregate(orders_bound, groupBy region, sum flag), i.e. driver-sql's own mssql paging and bit cast. So the card's literal premise (dashboards on a federated SQL Server object run the native statement) is false. BUT two arms still reach a public door through the ObjectQL ECHO, which shares the constructs: generateSql (the /analytics/sql echo) on that same federated object answered `... GROUP BY region LIMIT 10 OFFSET 5`, and with only an offset `LIMIT 9223372036854775807 OFFSET 5` (objectql-strategy.ts:1068 calls the shared windowClauseSql with dialect mssql), neither of which SQL Server parses and neither of which the driver runs; and the echo's where/read-scope compilers (objectql-strategy.ts:1014, :1752) raise the membership / $empty refusal whose text says the dialect is not known. The aggregand arm (item 2) is native-only: the echo prints a bare SUM(flag) on every dialect. The native face IS selected for one more shape: an object routed to the mssql datasource with NO external block (measured: engine.execute ran `SELECT region AS ..., COALESCE(SUM(flag), 0) AS ... FROM \"orders_bare\" GROUP BY region LIMIT 10 OFFSET 5`). The runtime treats that object as NOT federated (objectql federated-object.ts isFederatedObject is a presence test, documented as deliberate), so its boot schema sync sends DDL that the federation-only driver refuses and the #4632 ERROR fires; no in-repo producer writes that shape.

Long-term: B keeps the paging spelling in one place (core) instead of a third copy, per the card's own rule.
