Using SQL To Calculate XIRR (Internal Rate of Return)

Thanks to binaryworld.net , I was finally able to get a sql way to calculate XIRR. After 2 long hours of search I found this site and the logic as well as the code works perfectly well! XIRR is a function in excel that calculates Internal Rate of Return based on payments/income over a period of time. Without further ado, here is the code (a slightly modified version from BinaryWorld.net. Happy XIRRing! -- First, CREATE XIRR Table to store values CREATE TABLE XIRRTempData( amt float, dt datetime, guid varchar(128) ) go create function dbo.XIRR( @d datetime, @GUID varchar(128) ) returns decimal(18,10) as begin /* USAGE: select @IRR = dbo.xirr(null, guid) select @IRR IRR, @IRR * 100 'IRR %' Note: Leave the first parameter (date) null if you wish to see the XIRR calculated as of the maximum date in the dataset provided else provide a specific date to see the XIRR calculated as the given date.

In the "Group On" section, add some constant value - for example ="" or ="ankeet" etc... you get the idea! 3. Select the newly created group "RowColorGroup" and enter the following in its "Value" property: =iif(RunningValue(Fields!RG1.Value & Fields!RG2.Value,CountDistinct,Nothing) Mod 2, "LightSteelBlue", "White") 4.

cannot create a column accessor for OLE DB provider "ibmdasql" for linked server

I have a linked server from Microsoft SQL 2008 to a DB2 server. Today when I tried to run a SELECT statement based on the linked server, I hit this error, "cannot create a column accessor for OLE DB provider "ibmdasql" for linked server". Earlier in the day, we had restarted the SQL Server Service. Running the following script on the 'affected' sql server should fix the issue. USE [master] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROC [dbo].[usp_enum_oledb_providers] AS exec sp_enum_oledb_providers GO sp_procoption 'usp_enum_oledb_providers', 'startup', 1 Restart the sql server service after running above script.
