About nanodbc

The ODBC extension allows DuckDB to seamlessly connect to any database that provides an ODBC driver, enabling you to query and analyze data from a wide variety of data sources without leaving the DuckDB ecosystem.

Key features: - odbc_scan(): Query tables from any ODBC data source - odbc_query(): Execute custom SQL queries against external databases - odbc_exec(): Execute DDL/DML statements without returning results - odbc_attach(): Attach all tables from an ODBC source as views in DuckDB - Cross-platform character encoding support - Automatic type conversion between ODBC and DuckDB types - Support for DSNs and direct connection strings

The extension works on Windows, macOS, and Linux platforms and has been tested with SQL Server, MySQL, PostgreSQL, Snowflake, SQLite, and many other databases. All functions use named parameters for better readability and flexibility.
