Definition
Function LookupMultipleData(vtReserved As Variant,pvtKeys As Variant,pvtValues As Variant) As Variant
Parameters
vtReserved
A Variant reserved for future use. The LookupData method ignores any value stored in this parameter.
pvtKeys
A Variant that identifies the columns in which to search for the data. This Variant can be either a SimpleList object or an Array.
pvtValues
A Variant that identifies the values for which to search. This parameter can be either a SimpleList object or an Array.
Return Values
If this method completes successfully, it returns a Variant that references a SimpleList object that consists of one or more Dictionary objects, one for each row of data returned.
Error Values
This method sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.

Example
' Order is a Commerce.OrderForm object; OrderFormStorage is
' an initialized Commerce.DBStorage object
Order.order_id = "Order_tmp"
Order.shopper_id = "Shopper_tmp"
OrderFormStorage.InsertData(Null, Order)
OrderFormStorage.LookupMultipleData(Null, Array("order_id"), _
Array("Order_tmp"))
