SQL assistant
Built-in SQL functions that use AI to help you work with SQL. Generate SQL queries, execute read-only questions directly, fix errors, explain queries, and more.
These functions can be useful building blocks for AI-driven analytics solutions or used stand-alone on all MotherDuck surfaces (including the CLI).
To use external tools like Claude Desktop or Cursor with MotherDuck, see the MCP Server setup guide (or the local MCP server for self-hosted, read-write use).

Notes
SQL assistant functions operate on your current database by evaluating the schemas and contents of the database. You can specify which tables and columns should be considered using the optional include_tables parameter. By default, all tables in the current database are considered.
To point the SQL assistant functions at a specific database, execute the USE database command (learn more about switching databases).
These capabilities are provided by MotherDuck's integration with Azure OpenAI.
