Detailed Description

template<class AccessController = Transaction>
class MaxPacketInsertPolicy< AccessController >

An insert policy object that triggers a new INSERT statement if the object to be added would cause the statement to exceed a maximum size.

This differs from the SizeThresholdInsertPolicy in that it builds the VALUES expression and checks whether it would cause the length of the INSERT statement to exceed the maximum size.
