Rust ODBC bindings. ODBC (Open Database Connectivity) is an open standard to connect to a variaty of data sources. Most data sources offer ODBC drivers. There are two typical usage scenarios for ODBC:

  • Your appliciation is designed to work with a wide range of Databases without the need of redeploying it.
  • There is no native Rust driver in suitable quality available for your Database so you want to use the ODBC driver instead.

See also: Is ODBC the Answer?

This crate is currently tested against:

  • Microsoft SQL Server
  • PostgreSQL
  • MariaDB
  • SQLite

Current ODBC Version is 3.80.

This crate is build on top of the odbc-sys ffi bindings, which provide definitions of the ODBC C Interface, but do not build any kind of abstraction on top of it.


Check the guide for code examples and a tour of the features.


To build this library you need to link against the odbc library of your systems ODBC driver manager. It should be automatically detected by the build. On Windows systems it is preinstalled. On Linux and OS-X unix-odbc must be installed. To create a Connections to a data source, its ODBC driver must also be installed.


Nothing to do. ODBC driver manager is preinstalled.


sudo apt-get install unixodbc-dev

OS-X (intel)

You can use homebrew to install UnixODBC

brew install unixodbc


cargo build is not going to pick up libodbc.so installed via homebrew due to the fact that homebrew on ARM Mac installs into /opt/homebrew/Cellar as opposed to /usr/local/opt/.

You find documentation on what directories are searched during build here: https://doc.rust-lang.org/cargo/reference/environment-variables.html#dynamic-library-paths.

You can also install unixODBC from source:

  1. copy the unixODBC-2.3.9.tar.gz file somewhere you can create files and directories
  2. gunzip unixODBC*.tar.gz
  3. tar xvf unixODBC*.tar
  4. ./configure
  5. make
  6. make install

Linux / OS-X via Nix Flakes

Alternatively, if you're familiar with the Nix ecosystem or want to try it out, our wiki has a user contributed example on setting up a dev environment with Nix flakes.
