The Case of the Stolen Laptop: Mitigating the Threats of Equipment The

The fear of having laptops stolen is a huge worry for all organizations. Maybe it’s even happened to you (I hope not!). The solution is simple, really -- don’t let your laptop get stolen. (I can hear you laughing now.) Keep the thing with you at all times, or leave it in your hotel room when you don’t want to carry it around. Yes, everyone has heard the warnings about hotel room theft, but I’ve never had something stolen from a hotel room and I spend well over 200 nights a year in hotels. (If you travel to a location where the general population has kleptomaniac tendencies, stay in hotels that offer safes in the room.) You’re far more likely to leave your laptop or PDA or smart phone or USB drive lying on the seat in a taxi or on the counter at a bar.

Exploring 'ON DELETE SET NULL' in SQL Server 2005

At first glance, the 'ON DELETE SET NULL' option in SQL Server 2005 may not seem like a big deal, but once you've seen how it can be used, I think you will be impressed. The basics? If Order.CustomerID has a foreign key to Customer.CustomerID and a customer is deleted, 'ON DELETE SET NULL' causes the CustomerID field in each of that customer's orders to be set to NULL.

Migrating Microsoft Access Applications to SQL Server

Microsoft Access targets individual information workers and small teams that use the Microsoft Office System to track, manage, prioritize, and act upon an increasing volume of business information. The data stored in these databases rarely justifies moving to a more robust platform until the application begins expanding into departmental scenarios. When this happens, it is worthwhile to consider moving the data into a more robust platform for enhanced reliability, scalability, and greater IT control. In most cases, the data can be moved through a process called "upsizing" while the Access application front-end continues to provide information workers with access to critical data. Microsoft has created resources in the following three categories to help manage Access data in your organizations:

Question of the Day

Incremental Statistics

I have run this on SQL Server 2022 for the Sales database:

ALTER DATABASE Sales SET AUTO_CREATE_STATISTICS ON (INCREMENTAL = ON)
I then run this in the Sales database:
USE Sales
GO
CREATE STATISTICS CustomerStats1 ON dbo.Customer (CustomerKey, EmailAddress) WITH INCREMENTAL = OFF
The dbo.Customer table is partitioned. How are statistics created?
