A minimal C++ wrapper for the native C ODBC API, simplifying database connectivity with modern C++.
nanodbc is a small, modern C++ wrapper library for the native C ODBC (Open Database Connectivity) API. It simplifies database connectivity by providing a clean, type-safe C++ interface that reduces the verbosity and complexity of raw ODBC calls. The library enables C++ applications to interact with various database systems through ODBC drivers using concise, RAII-based code.
C++ developers building applications that need to connect to multiple database systems via ODBC, particularly those working on cross-platform projects or who prefer a minimal, dependency-light database abstraction layer.
Developers choose nanodbc because it dramatically simplifies ODBC usage with modern C++ idioms while adding almost no overhead. Its minimal design, lack of mandatory dependencies, and strong cross-platform support make it ideal for projects where lightweight, future-proof database connectivity is essential.
A small C++ wrapper for the native C ODBC API | Requires C++14 since v2.12
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Requires only standard C++ and ODBC headers/libraries, with no external dependencies unless explicitly enabled—this keeps the library lightweight and easy to integrate, as highlighted in the build options.
Uses C++14 and later standards for type-safe, RAII-based objects with value semantics, making database operations concise and reducing boilerplate compared to raw ODBC calls.
Works on Linux, macOS, and Windows with both unixODBC and iODBC drivers, evidenced by the comprehensive CI build status and testing suites for multiple platforms.
Offers optional Unicode support with configurable string types (std::u16string or std::u32string) via the NANODBC_ENABLE_UNICODE build option, catering to internationalization needs.
Adheres to a minimalist philosophy, so it lacks advanced features like ORM, connection pooling, or query builders—users must implement these manually, as the README states it wraps ODBC without adding major features.
The README notes issues with iODBC and Unicode, where sizeof(SQLWCHAR) differences can lead to ABI incompatibilities, potentially causing build or runtime failures unless workarounds are applied.
Future work sections admit the need for improved documentation, including more examples and details, which can slow down onboarding and troubleshooting for complex use cases.
