FAQPage Schema

How do I query multiple databases like SQLite, PostgreSQL, and MySQL from the command line?▼

Execute queries across SQLite, PostgreSQL, and MySQL using environment variable-based connections (DATABASE_URL, SQLITE_DB). The Skill routes queries to the correct database system and returns results directly, eliminating manual connection switching.

Can I generate SQL queries from natural language descriptions?▼

Yes, the Skill uses Gemini to generate SQL queries from natural language. Describe what you need—like analyzing user signups—and it writes, explains, and executes optimized queries across your database.

How do I inspect database schemas and run migrations safely?▼

Schema inspection reveals table structures, columns, and relationships across databases. The Skill supports safe migration workflows via CLI, letting you preview changes and apply them with confidence across development and production environments.

Does this work for ad-hoc queries in development and testing environments?▼

Yes, the Skill is designed for development, testing, and lightweight production environments. It excels at ad-hoc queries, schema inspection, and one-off analysis without requiring persistent infrastructure.

Can I export data from my database and view execution plans?▼

The Skill supports data export to multiple formats and generates explain plans to show how queries execute. This lets you optimize queries and audit database performance across SQLite, PostgreSQL, and MySQL.

What databases does this support, and do I need clients installed?▼

Supports SQLite, PostgreSQL, and MySQL. The Skill requires sqlite3, postgresql-client, and mysql-client as CLI dependencies, which you install once to enable cross-database operations.
