The ODBC back-end requires access to an ODBC driver manager as well as ODBC drivers for the underlying database server. CLSQL has been tested with unixODBC ODBC Driver Manager as well as Microsoft's ODBC manager. These driver managers have been tested with the psqlODBC driver for PostgreSQL and the MyODBC driver for MySQL.
Use
(asdf:operate 'asdf:load-op 'clsql-odbc)
to load the ODBC back-end. The database type for the ODBC back-end is :odbc.
