$driver->prepare(

Overview

There are four basic types of objects:

  • mef\Db\Driver\DriverInterface - The core driver that the majority of application code uses. It has methods such as prepare, query, and execute.
  • mef\Db\RecordSet\RecordSetInterface - The results of a query. It can be iterated over as an array or an iterator.
  • mef\Db\Statement\StatementInterface - A statement that has been prepared, but not yet queried. Its query method returns a RecordSetInterface.
  • mef\Db\TransactionDriver\TransactionDriverInterface - A driver to handle transactions. The NestedTransactionDriver is the preferred driver. It works with any database that supports save points.
