✨ Features

🗄️ Supported Databases

🚀 Write Complex DB Code in Seconds + DB AI Copilot

Generate, explain, fix, and refactor SQL from plain English — or straight from an error in the gutter. Your built-in AI pair-programmer for databases.

• Write Complex DB Code in Seconds — generate and execute complex SQL instantly with AI assistance, no manual query-writing required
• DB AI Copilot — ask questions in plain English, get queries, fixes, and tuning suggestions in return
• Create with AI — tables, views, procedures, and triggers, generated from the tree
• Providers: integrated Cloud, OpenRouter, Groq, OpenAI, Anthropic, Ollama, or your own custom endpoint

🧩 Visual Query Builder

Drag tables from the connection tree, auto-detect relationships, build JOINs and filters visually, and drop the generated SQL into your editor.

• Multi-table JOINs with relationship hints
• Clause-aware column drag (SELECT, WHERE, ON, ORDER BY, …)
• Starters for SELECT, INSERT, UPDATE, DELETE, and more

⚡ Query Optimizer

Turn execution plans into an interactive tree, score each step, and get index recommendations and rewrite suggestions.

• Visual Explain, traditional plan table, and JSON views
• Index recommender driven by EXPLAIN and schema metadata
• Before/after comparison in the optimizer workbench

🔍 Slow Query Analyzer

Ingest slow query logs, rank expensive statements, and jump straight into optimization with context — no GUI demo yet, coming soon.

📊 Performance Monitor & Query Profiler

Debug when the database feels slow — open Performance Monitor on demand for CPU, locks, replication, and process list.

• Global status, engine metrics, and deadlock snippets
• Replication lag and health-oriented signals
• Config audit hints for server tuning

Query Profiler session

Use Query Profiler for stage-level timings on a session — start profiling, run SQL, and review where time is spent.

• Stage-level timings for queries in an active profiler session
• Compare runs without leaving the editor

🛠️ Usage

Adding a Connection

1. Click the + icon in the sqllens.ai sidebar

2. Choose your database type: MySQL, MariaDB, PostgreSQL, or SQLite

3. Enter connection details:

   For MySQL / MariaDB:

   • Connection Name
   • Host (e.g., localhost)
   • Port (default: 3306)
   • Username
   • Password
   • Default Database (optional)

   For PostgreSQL:

   • Connection Name
   • Host (e.g., localhost)
   • Port (default: 5432)
   • Username
   • Password
   • Default Database

   For SQLite:

   • Connection Name
   • Path to the local .sqlite / .db file (no host, port, or credentials needed)

4. The connection will be tested before saving

Browsing Databases

1. Expand a connection in the tree view
2. Browse databases/schemas, tables, views, and columns
3. View column metadata (type, nullable, keys)
4. For PostgreSQL, browse by schema; for SQLite, browse the single local file directly

✅ Requirements

• Visual Studio Code 1.85.0 or higher
• Node.js 18+ (for development only)

Database engines (any one or more):

• MySQL 5.7+ or 8.0+
• MariaDB 10.x+
• PostgreSQL 12+
• SQLite 3.x (no server install needed — works with local files)
