SQL Repositories

There are two SQL related repositories in Red Bird:

• redbird.repos.SQLRepo: Built around object-relational mapping

• redbird.repos.SQLExprRepo: Built around SQL expressions

Both of them relies on functionalities provided by SQLAlchemy. In most cases redbird.repos.SQLExprRepo is right choice as often it is less error prone as it is simpler. redbird.repos.SQLRepo is useful if you need to leverage more from SQLAlchemy’s ORM features.

They also differ in terms of how they do the connection:

• redbird.repos.SQLRepo: Relies on sqlalchemy.orm.Session

• redbird.repos.SQLExprRepo: Relies on sqlalchemy.engine.Engine
