mysql: bindings to the mysqlclient library

This library is a Haskell binding to the MySQL mysqlclient client library. It is a fairly faithful, low level library that implements most of the MySQL client API. The major departure from the C API is that in Haskell, resource management is mostly automatic and safe.

This library deliberately avoids the question of providing a “good” API. Its purpose is to serve as a base upon which higher-level libraries can be built.

Licensing

This library is BSD-licensed under the terms of the MySQL FOSS License Exception.

Since this library links against the GPL-licensed mysqlclient library, a non-open-source application that uses it may be subject to the terms of the GPL.

To do

  • Add support for prepared statements. The prepared statement API is huge and of dubious performance value, so it’s not currently a priority for us. Patches welcome!

Get involved!

We are happy to receive bug reports, fixes, documentation enhancements, and other improvements.

Please report bugs via the github issue tracker.
