Beating Backup Corruption

The most critical task for all DBAs is to have a Backup and Recovery strategy that ensures, every day, that in the event of a disaster they can restore and recover any database, within acceptable limits for data loss and downtime. Even with all the required backups in place, it's easy to miss subtle failings in the overall plan that can, and eventually will, defeat your recovery plans.  More »

Editorial - Still 32

I was listening to a presentation recently and the presenter talked about some of the restrictions in working with 32 bit SQL Server on 64 bit Windows hosts. Another person joked that any companies still running 32 bit software were way behind the times. I heard a comment that surely everyone runs 64 bit hardware these days, don't they?

Do they? How many servers in large companies are still running on the x86 architecture? I know I have old laptops still running those processors, though I'd like to think that most companies have a hardware refresh rate that's no longer than 5 years, and most laptops and servers would be x86.

The platform architecture, however, doesn't necessarily imply our software has been upgraded to 64 bit. There are problems with various drivers that won't run under 64-bit architectures. Excel is often a problem as SQL Server moves to 64-bit versions. There are 64-bit drivers, but the change, testing, etc. effort for many companies may not be worth pursuing. It can be annoying for us data professionals, but it's a valid business decision. The same argument often applies to those companies running SQL Server 2000 (or older versions).

Five or six years ago I heard a presenter that worked for a large Fortune 100 company say that their policy was for applications to last ten years. That included the hardware and software, since the cost of change, whether through new software or major upgrades, was significant. With many companies still running SQL Server 2000, I suspect that many companies have a similar, unofficial, policy. 

I don't know whether the majority of software we use in our careers is 32 bit or 64 bit, but I am sure that we will have to deal with the former for years to come. You can complain about it, but you better learn to work with it.

Question of the Day

Today's Question:

Using SQL SERVER 2012

/* Version:
Microsoft SQL Server 2012 - 11.0.2218.0 (X64)
 Jun 12 2012 13:05:25
 Copyright (c) Microsoft Corporation
 Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1) */

USE AdventureWorks2012

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

I create the following temporary table

CREATE TABLE #Seasons(Hdate DATE,Season VARCHAR(10))

I then execute the following T-SQL:

INSERT INTO #Seasons(Hdate,Season)  

   SELECT HireDate, CHOOSE(MONTH(HireDate),'Winter','Winter', 'Winter','Spring',   'Spring','Summer','Summer','Summer','Fall','Fall','Fall','Winter') AS Season_Hired  FROM  [HumanResources].[Employee] 

SELECT COUNT(Season),Season 
 FROM #Seasons 
 GROUP BY Season.

The questions are:  Which season has the least number of hires? Which season has the largest number of hires? (select 2)

Yesterday's Question of the Day

What is the difference between COALESCE and ISNULL? (choose 2)

Answer:

  • Coalesce can take more than two parameters, and IsNULL takes exactly two parameters
  • The result returned by coalesce depends on data type precedence

Explanation: COALESCE can use a variable number of paramters, where ISNULL takes just two parameters. The return type of COALESCE does depend on the data type precedence rules and only COALESCE is an ANDI standard function.

Ref: http://blogs.msdn.com/b/sqltips/archive/2008/06/26/differences-between-isnull-and-coalesce.aspx
