Answer 1

I don't know what items is in your code so I don't know how to get the items into a table valued parameter. I can help with that if you need it but I would need to know what that object is.

Regardless you could do something like this on the sql side. Then you simply execute this procedure with your items collection as inbound parameter.

create type Items as TABLE
(
    ItemID int
    , Quantity int
)

GO

create procedure UpdateItemsBulk
(
    @Items Items READONLY
) as

    set nocount on;

    Update i
    set QuantitySold = items.Quantity
    from items i
    join @Items items on items.ItemID = i.ItemID

GO
