How do I get my Stored Procedure to use a function? The function takes in four parameters...amount, current currency, currency to convert to, and todays date...I am trying to use the function which does currency conversion to be used within my procedure to convert from one currency to another. For instance, am in the code below, am trying to use a function to convert from US dollar to CA dollar. My challenge in implementing the function in this stored procedure since the function already works.

Stored Procedure:

Create Procedure [dbo].[TSP_PricingItem]
@Price_Group VarChar(254),
@From_Item VarChar(31),
@To_Item VarChar(31),
@Price_Level VarChar(254)
As
--
Set NoCount On

/*****************************************************************************
* Reset parameter fields
*****************************************************************************/
If @From_Item = 'ALL'
Set @From_Item = '00000000000000000000'

If @To_Item = 'ALL'
Set @To_Item = 'ZZZZZZZZZZZZZZZZZZZZ'

-- Create Table Variable and populate with list of Price Groups to report
Declare @tmp VarChar(254)

Declare @PriceGroupTbl Table (PriceGroup VarChar(11))

If @Price_Group = 'ALL' -- Insert all price levels from the master table
Insert @PriceGroupTbl (PriceGroup)
Select PriceGroup From tbl09000
Else
Begin
-- loop to get all but last one when there is more than one object
While CharIndex ( ',', @Price_Group) > 0
Begin
Set @tmp = SubString(@Price_Group, 1, CharIndex ( ',', @Price_Group) - 1)
Set @tmp = LTrim(@tmp)
Insert @PriceGroupTbl (PriceGroup) Values (@tmp)
Set @Price_Group = Ltrim(SubString(@Price_Group, CharIndex ( ',', @Price_Group) + 1, Len(@Price_Group) - CharIndex ( ',', @Price_Group)))
Continue
End
-- add last one
Insert @PriceGroupTbl (PriceGroup) Values (@Price_Group)
End

-- Create Table Variable and populate with list of Price Levels to report
Declare @PriceLevelTbl Table (PriceLevel VarChar(11))

If @Price_Level = 'ALL' -- Insert all price levels from the master table
Insert @PriceLevelTbl (PriceLevel)
Select PrcLevel From tbl08000
Else
Begin
-- loop to get all but last one when there is more than one object
While CharIndex ( ',', @Price_Level) > 0
Begin
Set @tmp = SubString(@Price_Level, 1, CharIndex ( ',', @Price_Level) - 1)
Set @tmp = LTrim(@tmp)
Insert @PriceLevelTbl (PriceLevel) Values (@tmp)
Set @Price_Level = Ltrim(SubString(@Price_Level, CharIndex ( ',', @Price_Level) + 1, Len(@Price_Level) - CharIndex ( ',', @Price_Level)))
Continue
End
-- add last one
Insert @PriceLevelTbl (PriceLevel) Values (@Price_Level)
End

How would you use the function outside the stored procedure? Have you tried doing the same inside the stored procedure? Inside or outside should make a difference.
