Pinal Dave is someone whose blogs I've followed for years, probably almost a decade. He has posted a puzzle on his website. If you know the answer, head over to the site, link above and respond!

Puzzle: Write a Shortest Code to Produce Zero
Conditions
1. Do not use numbers and arithmetic calculation
2. Do not use the function 'LEN()'
3. Do not use 0 in the code
4. Length of the entire code should be less than 19 characters

Good Luck!

SELECT ISDATE('a') is 19 characters and therefore does not meet the rules.
My answer: SELECT @@ERROR on a fresh new window of SSMS.

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.
