- Result sets are now single-use; this is required for PDO drivers (PDO result sets are not rewindable)
- Change savepoint exceptions to be simple database exceptions; codes remain the same
- Revamped design of Query class to be more consistent and predictable, and generally suck less
- Removed special case for Query class in Statement class
- Cleaned up database schema somewhat
- Driver->prepare() can now take a new Database\Query object as the first parameter
- The Query class allows for building a complex query out of a main body, common table expressions, WHERE coniditions, ordering conditions, a limit, and offset
- The subscriptionList method is the prototypical example of usage
- The experimental articleList method will in time be adapted to use this as well
- A generic means of specifying a selection context is forthcoming; this would remove subscriptionList's $folder and $id parameters, for instance
The type parameters of Db\Driver::prepare() and the parameters of Db\Statement::run() can now be arrays, which will be iterated over recursively to bind scalar values to the SQL statement.
This simplifies the construction of arbitrary UPDATE statements (the WHERE clause no longer needs to be taken into account) and should make it clearer what is happening in these cases.
It should also simplify the creation of IN() clauses down the road if they become necessary.
