    Description copied from class: AbstractCreateStatementInterceptor
    
    This method will be invoked after a successful statement creation. This method can choose to return a wrapper around the statement or return the statement itself. If this method returns a wrapper then it should return a wrapper object that implements one of the following interfaces. Statement, PreparedStatement or CallableStatement
    
    Specified by:
    
    createStatement in class AbstractCreateStatementInterceptor
    
    Parameters:
    proxy - the actual proxy object
    method - the method that was called. It will be one of the methods defined in AbstractCreateStatementInterceptor.STATEMENT_TYPES
    args - the arguments to the method
    statement - the statement that the underlying connection created
    
    Returns:
    a Statement object
  - closeInvoked
