Represents a prepared statement.

Some methods in that class are purposefully commented out. Due to a change in how PHP defines PDOStatement, we can't define a signature for those methods that will work the same way between versions older than 5.2.6 and later versions. See http://bugs.php.net/bug.php?id=42452 for more details.

Child implementations should either extend PDOStatement:

class DatabaseStatement_oracle extends PDOStatement implements DatabaseStatementInterface {}

or define their own class. If defining their own class, they will also have to implement either the Iterator or IteratorAggregate interface before DatabaseStatementInterface:

class DatabaseStatement_oracle implements Iterator, DatabaseStatementInterface {}
