Linked Server to IBM AS400 from MS SQL Server

I am back after a while! I have accepted a new position which means more responsibilities. I now lead a Business Intelligence initiative. This opportunity is exciting and interesting. I get to do what I love to do!

So first task at hand was to be able to access data from the AS400 system for ETL to MS SQL 2008. Simple, right? Simple? I thought so, but got stumped for the first few minutes and thought many others might have the same issue!



If you do not see IBMDA400, IBMDARLA and IBMDASQL as in the above screenshot, you are mssing some drivers.

Issue at hand - cannot find proper drivers on MS SQL installation to connect to the AS400 system. What you need to do is install IBM Access iSeries for Windows software on your SQL Server box.
http://www-03.ibm.com/systems/i/software/access/windows/index.html. After installing this software, logout and log back in.

Once that is done follow these steps.
1. Navigate to SQL Server Installation > Server Objects > Linked Servers


Notice the IBMDA400, IBMDARLA and IBMDASQL providers? If you do not see those you are missing something. Checkout the documentation at:
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/index.jsp?topic=%2Frzaik%2Frzaikoledbprovider.htm
http://publib.boulder.ibm.com/infocenter/iseries/v5r3/index.jsp?topic=%2Frzaik%2Frzaikoledbprovider.htm


2. Right-click on Linked Servers and select New Linked Server


3. In the resulting window enter the appropriate information.

Provide a name for "Linked Server:". It could be any name.
Select the Provider as displayed above.
Provide the server name or IP address in the Data Source.
As you see, Location is not necessary.
Pick your default Catalog.

If you got till here without much trouble, rest is very self explanatory.

Let me know if you have any question!

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.

Alternating Row Background Color For SSRS Matrix (Pivot Table)

I had a tough time to apply alternate row colors to a SSRS Matrix and finally figured out! Without further ado, here it is... Assume you have a matrix with more than 1, lets say 2 row groupings; RG1 and RG2. 1. Right-click on RG2 (innermost row group), and select "Insert Group"; for simplicity call it "RowColorGroup" 2. 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. Select the "BackgroundColor" property of "RowColorGroup" and enter "=Value" 5. Set the width of "RowColorGroup" to 0pt and "CanGrow" to false 6. Select the data cell(s) and set their "BackgroundColor" pro...

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.
