Class SqlType

java.lang.Object
  |
  +--org.enableit.db.SqlType

All Implemented Interfaces:

java.io.Serializable

public class SqlType

extends java.lang.Object

implements java.io.Serializable

This class has a primary purpose of representing a null value to be inserted into some SQL call handled by the proxy objects

This is necessary to allow the proxies to receive a null object yet still provide the JDBC driver with a known object type as required by PreparedStatement.setNull

The integer used in the constructor should be one of the static final members of Types
