Use this package to help with introspective operations against databases that support information_schema . It supports generating view-class definitions from the database schema.
This was originally clsql-postgres-introspect, though this is a bit far removed from that.
I have used this to successfully generate view-classes for PostgreSQL, MSSQL (through freetds and unixodbc), and mysql.
This project does not attempt to be a persistence layer. It also makes quite a few assumptions about what should be generated and with what types that may not match your desires or existing notions. As such this code might only be useful as a jumping off point for creating your own custom clsql ORM.
Please see the examples directory
