The table names used are determined by the class variables
associations_table_name and nonces_table_name. To change the name
of the tables used, pass new table names into the constructor.
To create the tables with the proper schema, see the createTables
method.
This class shouldn't be used directly. Use one of its subclasses
instead, as those contain the code necessary to use a specific
database. If you're an OpenID integrator and you'd like to create
an SQL-driven store that wraps an application's database
abstraction, be sure to create a subclass of
{@link Auth_OpenID_DatabaseConnection} that calls the application's
database abstraction calls. Then, pass an instance of your new
database connection class to your SQLStore subclass constructor.
All methods other than the constructor and createTables should be
considered implementation details.
