SQL Server 2005- how to pass e.g. 5 Orders(ID,Price,Discount) as variables for 1 transaction

Hi, I have a nr of records(e.g. Orders) which need to be grouped into one Batch

OrderID	Price Discount
1	5.12	1.00
2	6.00	1.05
3	7.00	0
4	8.00	0
5	9.00	0

Select allOpen in new window

The problem is that I work with SQL 2005, and I cannot pass a table variable with the above mentioned example.
I for e.g. need to send these 5 lines to a proc, and need to insert all 5 lines (they can vary and there is no maximum nr of lines set - but I am aware that the
variables I pass to SQL 2005 have a character limit of 8000 chars - there is a check for this is and it will not be reached) in a transaction or rollback the transaction.

I do not have an idea of how I will get the above lines into variables in order to pass them as a variable


Example:

Alter Procedure sp_Batch
(
@XYZ nvarchar(max)
)


BEGIN TRANSACTION

	Insert into Batch(OrderID, Price, Discount)

COMMIT

Select allOpen in new window

I am desperate and am beginning to think of methods that are not good.
E.g.

Alter Procedure sp_Batch
(
@OrderIDs nvarchar(max)
@Prices nvarchar(max)
@Discounts nvarchar(max)
)

set @OrderIDs  = '1,2,3,4,5'
set @Prices    = '5.12, 6 , 7, 8,9 '
set @Discounts = '1, 1.05,0,0,0

Select allOpen in new window

This would get me all the variables, but now I do not know how to get them back into a @Table variable.

Manually it would have been:

Insert into @Table(OrderID,Price,Discount) select 1,5.12,1 
Insert into @Table(OrderID,Price,Discount) select 2,6,1.05 

Select allOpen in new window

etc

Any suggestions on how I can get

OrderID	Price Discount
1	5.12	1.00
2	6.00	1.05
3	7.00	0
4	8.00	0
5	9.00	0

Select allOpen in new window

into a few parameters in order to rebuild a table variable in SQL that looks like the aforementioned please?
