Lets deploy and test it step by step.

You can download the C# code, or the pre-compiled binary from the Frog-Blog download section. In Excel this is a pretty simple job, as Microsoft helpfully provide a number of functions to do just that (namely PMT, FV, IPMT and PPMT).

Initially I coded them up as SQL Server functions, only to find that the internal rounding that SQL performs renders the results too inacurate to be usable.

In this article, I will share, how to use common excel financial functions in SQL Server using CLR. Given below are some examples of above functions. Present Value of Annuity in SQL Server as a User defined function and shared it.

This is a collection of thoughts, ramblings and ideas that we think would be useful to share. There are two methods to deploy above CLR functions in SQL.

Documentation on over 250 SQL Server financial functions including examples that can be copied directly into SSMS.

The Excel IPMT function can be used to calculate the interest portion of a given loan payment in a given payment period.
Now, we are ready to use Excel financial function in SQL.

In SQL Server however we do not have the luxury of having ready made functions, so I set about making my own. Required fields are marked *, 367,560 Spambots Blocked by Simple Comments. Use the SQL Server scalar function IPMT to calculate interest payment for a given period for an annuity based on periodic, constant payments and a constant interest rate. I must thank Kevin/MWVisa1 for writing a superb article explaining the finer points of the calculation process in his post here, on which the bulk of this code is derived. Create assembly and CLR functions in SQL Server. IPMT() Function IPMT() or the interest portion of a future payment specified by the period argument introduced in the Excel version: IPMT(interest_rate, period, number_payments, PV, FV, Type) Period Period is the only different value and has already been discussed above in our FV() section and is stored in cell {B3}. First download the source code from here and extract it. Note : You don’t need to install Excel on the server.

These are designed to mirror the parameters and results of the Excel functions, and have been written in C# using Visual Studio 2008, and tested against SQL Server 2008 Enterprise. SQL Server can then import them as scalar functions, to be used by any query that requires them. CDRRate - CDR Rate given the loan default amount. TOTALINT - total interest on a loan or lease, AMORTSCHED - generate a loan amortization schedule, Balloon - cash flow schedule for a loan with periodic payments of interest (only) and with the principal paid at maturity, Bullet - cash flow schedule for a loan with a single payment of principal and interest at maturity, CDRCASHFLOW - a cash-flow schedule for a loan with a fixed periodic payment with Conditional Prepayment Rates (CPR) and Constant Default Rates (CDR) applied. In SQL Server however we do not have the luxury of having ready made functions, so I set about making my own.
