Implement execute method in Insert class. Provide support for lastInsertId functionality since this is required to get a fully functioning site.

Define the escape character to use for LIKE statements. Double forward slash does not work in Akiban.

Temporary workaround for the fact that a column cannot be explicitly told to use a default value on INSERT in akiban.

Override Connection methods related to nested transactions. Akiban does not support savepoints at this time.

Implementing 2 methods that are abstract in Connection base class and so need to be implemented in Akiban Connection class.
