Restart the IDE when prompted. +3. Open the **AskSQL** tool window (usually a tab on the right/bottom edge). +4. **Add a connection**: on the empty-state screen, click **Add Connection** (Postgres, + MySQL, SQLite, DuckDB, Oracle, or MongoDB), or click **Try sample data** for a + ready-made SQLite database with no setup, good for a first look. +5. **Configure a model**: click **Configure a provider** to add an API key for + OpenAI/Anthropic/Gemini/Groq/NVIDIA/etc., or **Use a local model** if you already + have Ollama or LM Studio running (detected automatically, no API key needed). +6. Type a question in plain language, review the generated SQL (and, unless you turned + off "require approval" in Settings, click **Run**), and see the result.

To keep the Kotlin guard +from silently drifting from the published core's security behavior, `tools/parity/` +runs a corpus of SQL statements through the **published** `@asksql/core` package and +records the verdicts as committed JSON vectors (`vectors/guard.json`, +`vectors/prompts.json`). `GuardVectorTest` and `PromptParityTest` replay those vectors +against this Kotlin port in every `./gradlew test` run. + +```bash +./gradlew parityVectors # regenerates tools/parity/vectors/*.json (needs Node + npm) +git diff tools/parity/vectors/ # review before committing; CI fails on any diff +``` + +The parity contract is a **subset**, not equality: the Kotlin guard must never allow +what core blocks (checked and enforced); it may occasionally block something core +allows, if JSqlParser's grammar coverage differs from node-sql-parser's; that +direction is safe (a stricter guard, not a weaker one) and is logged, not failed. + +Node is used **only** by this tooling, in CI and in local dev; never bundled into +the plugin, never required on an end user's machine. + +## Architecture at a glance + +``` +com.rahulmahadik.asksql.ide/ +├── model/ Dialect, SchemaCatalog, ResultSet, GuardPolicy, EngineEvent, +│ MongoGuardPolicy/MongoGuardVerdict: pure data +├── guard/ SqlGuard (JSqlParser AST walk), SqlLexer, DenyLists: the SQL engines' +│ security boundary; MongoGuard/MongoDenyLists: MongoDB's separate, +│ allowlist-first equivalent (no server-enforced read-only floor exists +│ for Mongo, so the guard alone carries that guarantee) +├── engine/ EnginePipeline (ask/execute/explain/suggestFix) for the five SQL +│ engines, Prompts, Extract, CatalogPruner (shared with Mongo), +│ HallucinationChecks, HistoryStore (in-memory only); +│ MongoEnginePipeline/MongoPrompts/MongoExtract: MongoDB's own, +│ non-SQL pipeline (see the class doc on MongoGuard for why this +│ isn't just a parameterization of EnginePipeline) +├── llm/ LlmClient (OpenAI-compatible / Anthropic / Gemini over java.net.http), +│ ModelDiscovery (Ollama/LM Studio zero-key probing), BaseUrlGuard +├── db/ ConnectionRegistry (project service), JdbcConnectionFactory, +│ ReadOnlySession, JdbcExecutor, DriverProvisioner, db/introspect/* +│ (Postgres/MySQL/SQLite/DuckDB/Oracle, JDBC-based); +│ MongoClientRegistry/MongoClientFactory/MongoQueryExecutor, +│ db/introspect/MongoIntrospector (sampling-based schema inference, +│ no catalog to query): MongoDB's separate, non-JDBC connection path +├── settings/ AskSqlAppSettings / AskSqlProjectSettings (SerializablePersistentStateComponent), +│ AskSqlSecrets (PasswordSafe), ConnectionMerger, Configurables +├── ui/ Tool window: ChatPanel, TranscriptView, TurnPanel, SqlBlockPanel, +│ ApprovalBar, ResultTablePanel, SchemaTreePanel, OnboardingPanel +├── actions/ AddConnection, TrySampleData, UploadFileToDuckDb, RefreshSchema, +│ OpenSettings, AskAboutSelection, OpenSqlInScratch, CollectDiagnostics +└── integrations/database/ Optional, purely-reflective DataGrip datasource import +``` + +Security and privacy invariants (see the plan doc for the full list): + +- The AST guard (`SqlGuard`) runs on **every** SQL string before **every** execution + (MongoDB: `MongoGuard`, on every generated pipeline). +- Every JDBC session is additionally forced read-only at the engine level + (`ReadOnlySession`): defense in depth beyond the guard. MongoDB has no + session/connection-level read-only flag to arm the same way, so for that + engine `MongoGuard` is the only floor, not defense-in-depth alongside one + (see its class doc). +- Only schema is ever sent to the configured AI model. For low-cardinality + columns, a small sample of distinct **values** (up to 24, capped in length) is also sent so the + model can write correct `WHERE` clauses against real enum-like data (e.g. status + codes) instead of guessing. This is genuinely a sample of real column contents, + not schema metadata; full row data (arbitrary query results) is never sent. +- Chat history and query results are **in-memory only**; nothing is written to disk + except settings, and secrets live only in the OS keychain via PasswordSafe. +- Zero telemetry. + +## Required database privileges + +AskSQL only ever runs read-only statements (enforced by the guard plus, on most +engines, the session itself, see above), so the connecting user needs no write +grants. A dedicated, read-only account is recommended over reusing an +application's own credentials: + +- **Postgres**: `GRANT CONNECT ON DATABASE TO ;` plus + `GRANT USAGE ON SCHEMA TO ;` and + `GRANT SELECT ON ALL TABLES IN SCHEMA TO ;` (and + `ALTER DEFAULT PRIVILEGES ... GRANT SELECT ON TABLES` so future tables inherit + it). Introspection also reads `pg_catalog`/`information_schema`, which is + world-readable by default. +- **MySQL**: `GRANT SELECT, SHOW VIEW ON .* TO ''@'%';`: `SHOW VIEW` is + needed for view definitions during introspection, not for querying. +- **Oracle**: `GRANT CREATE SESSION TO ;` plus `SELECT` on the target + objects (or `SELECT ANY TABLE` for a schema-wide read-only account). + Introspection reads only the `ALL_*` data dictionary views (`ALL_TAB_COMMENTS`, + `ALL_COL_COMMENTS`, `ALL_TABLES`, `ALL_OBJECTS`), never `DBA_*`, so no extra + catalog role is needed beyond the object grants above; `ALL_*` views already + show whatever the connecting user has been granted. +- **MongoDB**: the built-in `read` role on the target database (`db.grantRolesToUser`) + is sufficient; introspection samples documents and reads `listCollections`/ + `listIndexes`, all covered by `read`. +- **SQLite / DuckDB**: file-based; whatever OS file permission lets the IDE + process open the file is the only "grant" that applies; the plugin additionally + opens the file itself in read-only mode (see `ReadOnlySession`). + +## Debugging the plugin + +`./gradlew runIde` launches a sandboxed IDE attached to your run/debug configuration;

+    AskSQL
+    Rahul Mahadik
+
+    AskSQL in a JetBrains IDE: the schema tree above the chat panel, a plain-language question turned into SQL with results

+        
AI database chat inside your IDE. Ask a question in plain language, review the generated
+        SQL, approve it, and get results.

+        
    
+            
  • Read-only by design. An AST-based SQL guard plus an enforced read-only database
+                session block anything that is not a SELECT.
    • 
+            
  • Bring your own model. OpenAI, Anthropic, Google Gemini, Groq, NVIDIA, Azure
+                AI Foundry (via an OpenAI-compatible endpoint), or a local model through Ollama or
+                LM Studio (no API key needed).
    • 
+            
  • Six databases. Postgres, MySQL, SQLite, DuckDB, Oracle, and MongoDB.
    • 
+            
  • Or no database at all. Point it at CSV, TSV, JSON, Parquet or Excel files and ask
+                questions about them directly, joining across files. No server to install.
    • 
+            
  • Private by default. Zero telemetry. Only schema and small samples of low-cardinality
+                values reach the model; secrets live in your OS keychain.
    • 
+            
  • Every JetBrains IDE. IntelliJ IDEA, DataGrip, PyCharm, WebStorm, GoLand, PhpStorm,
+                Rider, CLion, RubyMine, RustRover, and Android Studio (2025.2 and newer).
