I have a table with the the following columns

CustID CustName PrincipleAmount NumberOfYears DepositType

I have created a function that sets the principle rate

CREATE FUNCTION [dbo].[IntRate](@NumberofYears decimal(7,4))

RETURNS decimal(7,4)

AS

BEGIN

DECLARE @rate decimal(7,4)

if @NumberofYears>=20 set @rate ='.15'

else if @NumberofYears >= 11 set @rate ='.125'

else if @NumberofYears>= 6 set @rate ='.10'

else if @NumberofYears>= 4 set @rate ='.075'

else if @NumberofYears>= 1 set @rate ='.05'

else set @NumberofYears = '0'

RETURN @rate

END

no i need to be able to calculate the final amount taking variable from both of these tables

PROBLEM:

I am unclear how to call the variable from the function

problem trying to solve:

Final Amount (A) – Takes three inputs P, N, and Deposit Type and returns the final amount using either simple interest formula or compound interest formula, depending upon the deposit type. For the calculation of R it uses the rate of interest function.

formulas: A=PNR (for simple interest)

A=P(1+r)^N (for compound interest)

so i know i need an if statement based on the deposittype

I need to know how to get started or how to call the rate from the function.

Thanks

? else set @rate = 0

and you shouldn't have quotes around the rates

LIKE

SELECT case ratetype when 'S' then numberofyears * AMT * [dbo].[IntRate](NumberofYe

else amt * (1 + [ dbo].[IntRate](NumberofYea

end

FROM TABLE...

BUT really you should have an interest rate table which would hold the correct rate

e.g.

loanname, period, rate
