The ALL, SOME and ANY predicates aren't much used in SQL Server, but they are there. You can use the Exists() predicate instead but the logic is more contorted and difficult to read at a glance. Set-oriented predicates can greatly simplify the answering of many real-life business questions, so it is worth getting familiar with them. Joe Celko explains.
Steve Jones gave a keynote, and has a little fun this week with the topic of his talk.
Although SQL Server for Linux removes the concern that adopting SQL Server forces you to also adopt the Windows platform, it could also provide a useful alternative platform, and a more obvious alternative to Oracle. There are, however, several obvious concerns as to how such a product could ever achieve parity with the existing Windows-based product. Microsoft have made an interesting move with several ramifications, as Robert Sheldon explains.
There are times when you want some users to see part of a column value but not the whole thing, but you want other users to see the complete column value without any masking. The new SQL Server 2016 Dynamic Data Masking feature will allow you to define these different kinds of masking rules - Greg Larson explains.
Monitoring your systems is critical to ensuring security and stability. Steve Jones shares a few thoughts on where monitoring might go with more computer assistance in the future.
DBCC CHECKDB is a built-in SQL Server command that allows you to check database integrity and consistency in one simple command, but running it on large databases can be a nightmare. In this article, Ahmad Yaseen explains how you can enhance the command to run faster in SQL Server 2016.
Microsoft has dramatically changed the way they develop software, in a very public way, as Steve Jones notes.
In this tip, we will talk about PowerShell and SQL Server Log and Data Files.
Desired State Configuration (DSC) allows you to automate the way that you manage configuration data for software services as well as the environment in which these services run. DSC uses a set of built-in and custom 'resources' as the building blocks for a configuration. If you have specific requirements you may need to create the relevant resource to make the configuration happen. Nicolas Prigent provides a practical guide to DSC resources.

I try to run this code on SQL Server 2022. All the objects exist in the database.
CREATE OR ALTER VIEW OrderShipping
AS
SELECT cl.CityNameID,
cl.CityName,
o.OrderID,
o.Customer,
o.OrderDate,
o.CustomerID,
o.cityId
FROM dbo.CityList AS cl
INNER JOIN dbo.[Order] AS o ON o.cityId = cl.CityNameID
GO
CREATE OR ALTER FUNCTION GetShipCityForOrder
(
@OrderID INT
)
RETURNS VARCHAR(50)
WITH SCHEMABINDING
AS
BEGIN
DECLARE @city VARCHAR(50);
SELECT @city = os.CityName
FROM dbo.OrderShipping AS os
WHERE os.OrderID = @OrderID;
RETURN @city;
END;
go
