From ea596d53c3fe6b1d9a0e09b215d8707d97c4493b Mon Sep 17 00:00:00 2001 From: rahulmahadik Date: Fri, 21 Aug 2026 21:55:19 +0800 Subject: [PATCH 1/4] Share the schema-hint budget evenly, and stop losing truncation A wide schema spent its column-hint probe budget on whichever tables were introspected first, so every table past roughly the fiftieth got no hints at all. The budget is now a fair share per table instead. The pruner's table cap was a fixed 40 regardless of the token budget, dropping a table the budget had room for. The cap now only guards a pathological schema; the budget decides what is sent, and one wide table can no longer evict every smaller table behind it in the same pass. A result whose row limit was lowered - rather than added where there was none - was not counted as truncated, so a "top 5000" that came back capped at 100 rows reported no warning. Both cases are now caught, on the flag and the message. DuckDB stopped silently truncating a schema past 100,000 total columns, and now rejects an oversized .sql upload before reading it into memory rather than risking an out-of-memory crash partway through. Oracle's JSON-array hint stopped emitting an unquoted identifier the database would reject. MongoDB now warns when a collection's field count passes the describe cap, instead of silently naming only the first 500. --- .changeset/mongo-field-cap-warning.md | 6 +++ .changeset/wide-schemas-and-truncation.md | 28 ++++++++++++ packages/core/src/catalog.ts | 46 +++++++++++++++----- packages/core/src/column-hints.ts | 10 +++++ packages/core/src/engine.ts | 17 ++++++-- packages/core/src/index.ts | 1 + packages/core/test/catalog-objects.test.ts | 38 ++++++++++++++++ packages/core/test/hint-probe-budget.test.ts | 38 ++++++++++++++++ packages/core/test/limits.test.ts | 11 +++++ packages/core/test/scale.test.ts | 44 +++++++++++++++++++ packages/duckdb/src/browser.ts | 11 +++++ packages/duckdb/src/index.ts | 22 +++++++--- packages/duckdb/src/shared.ts | 21 ++++++++- packages/duckdb/test/scale.test.ts | 35 +++++++++++++++ packages/duckdb/test/sql-upload.test.ts | 33 +++++++++++++- packages/mongodb/src/introspect.ts | 11 ++++- packages/mongodb/test/live.test.ts | 17 ++++++-- packages/mysql/src/introspect.ts | 4 +- packages/mysql/test/live.test.ts | 6 ++- packages/oracle/src/introspect.ts | 6 ++- packages/oracle/test/live.test.ts | 7 ++- packages/postgres/src/introspect.ts | 4 +- packages/postgres/test/live.test.ts | 9 ++-- packages/sqlite/src/index.ts | 6 ++- 24 files changed, 391 insertions(+), 40 deletions(-) create mode 100644 .changeset/mongo-field-cap-warning.md create mode 100644 .changeset/wide-schemas-and-truncation.md create mode 100644 packages/core/test/hint-probe-budget.test.ts create mode 100644 packages/duckdb/test/scale.test.ts diff --git a/.changeset/mongo-field-cap-warning.md b/.changeset/mongo-field-cap-warning.md new file mode 100644 index 0000000..514efd2 --- /dev/null +++ b/.changeset/mongo-field-cap-warning.md @@ -0,0 +1,6 @@ +--- +"@asksql/mongodb": patch +--- + +A collection with more than 500 distinct fields silently described only the first 500 to the model, +with no signal anything was left out.

An ordinary Android app database - a couple hundred tables, a handful of columns each - crosses that without trying, and failed to import at all with a message that read as a corrupt file. Columns are now read with PRAGMA table_info, one table at a time, which is what the npm package has always done and is why it was never affected. The same JDBC round-trip cost applied to primary keys, foreign keys and indexes: three calls per table, since none of getPrimaryKeys/getImportedKeys/getIndexInfo accept a pattern. MySQL and Oracle now read the whole schema's constraints in a handful of queries, matching what Postgres already did and what the npm packages already did - verified live against a real 200-table MySQL schema (706ms to 75ms) and a real 65-table Oracle schema (106s to 3.6s), output identical to the per-table path on every shape tried, including composite keys, self-references, and two foreign keys to one table. Approving and running a query used to re-guard text that already carried an injected LIMIT, so the fresh verdict reported no cap and the truncation warning vanished exactly when the reader was looking at the results. The ask-time verdict now survives into execute(). Oracle's dialect notes told the model to write FETCH FIRST while the schema-hint prompt told it not to - the two surfaces had drifted to contradict each other - and the byte-for-byte parity check that would have caught it only ever covered PostgreSQL; it now covers every engine.

If a name is an obvious misspelling of a real one (e.g. \"appoinment_equipment\" for \"appointment_equipment\"), use the real name and answer normally - never refuse over a spelling difference.\n- Prefer VIEWs over rebuilding their joins when a view answers the question.\n- Include a LIMIT (at most 1000) unless the query is a single-row aggregate.\n- Use the RELATIONSHIPS section for join paths. State assumptions briefly.\n- Only if the user explicitly asks you to WRITE an INSERT/UPDATE/DELETE/DDL statement, respond with exactly: IMPOSSIBLE: write requested - it can be proposed as text instead. Questions ABOUT data are never writes.\n- A question asking for an OPINION about the schema (how to improve it, what to change, which indexes to add) has no answer in rows: respond with exactly IMPOSSIBLE: schema advice requested.
