Pony wrappers and simple API for iODBC or unixODBC.

Status

"In Motion"™

Please feel free to test it and provide feedback on the design and API. Please don't assume that this current API is stable.

Installation

• Install corral
• corral add github.com/redvers/pony-odbc.git --version 0.3.1
• corral fetch to fetch your dependencies
• use "pony-odbc" to include it in your application
• use "lib:odbc" or use "lib:iodbc" for unixODBC or iODBC respectively
• corral run -- ponyc to compile your application

Dependencies

ODBC is an API designed to abstract access to databases, much like DBI or jdbc. Conceptually, it looks like this:

pony-odbc → unixODBC|iODBC → ODBC Database Driver

So, if you are using this database to connect to postgresql, you require either unixODBC or iODBC, and the ODBC driver for postgresql.

pony-odbc will happily connect to any number of different types of databases, as long as you have the backend ODBC driver for all the databases you need installed.

For example, in our github workflows, we have postgres, mariadb, and sqlite3 ODBC backends installed and we test on all of them concurrently.

Configuring access

ODBC data-sources are specified via "Data Source Name"s (DSNs). They can either be defined directly in your application as a string or configured scoped to a system/user via /etc/odbc.ini or ~/.odbc.ini

Please check your documentation for unixODBC/iODBC and your ODBC database driver for more details.

Here are some example configurations that we use in our test workflows:

[psqlred]
Driver=/usr/lib/x86_64-linux-gnu/odbc/psqlodbca.so
Description=A test database
Servername=127.0.0.1
Driver=PostgreSQL
Database=pony
UserName=pony
Password=pony

[mariadb]
Driver=/usr/lib/x86_64-linux-gnu/odbc/libmaodbc.so
Description=A test database
Servername=127.0.0.1
Database=pony
User=pony
Password=pony

[sqlitedb3]
Driver=/usr/lib/x86_64-linux-gnu/odbc/libsqlite3odbc.so
Description=A test database
Database=/tmp/testdba.db

Both unixODBC and iODBC provide tools to test the validity of your configuration independently of this library.
