Sql-Server

You’d think SQL Server 2000 would be long gone by now, but recently I had to restore a SQL Server 2000 database, and get it working on SQL Server 2022.

Now extended support for SQL Server 2000 ended on 9th April 2013.

SQL Server 2000 came in several editions: Enterprise, Standard, Developer, Personal, and the Desktop Engine or MSDE. I’m guessing most people would forget that there was ever a Personal edition. Regardless, this database was from an application that used an embedded database attached to the Desktop Engine or MSDE.

When working with SQL Server systems, it can be hard to remember the names of all the servers, to remember connection details for the ones that need SQL logins (instead of Windows authentication), and to remember other details of those servers, such as which environments they are part of (eg: production, UAT, test)

SSMS has a facility to help you to do this. It allows you to register server details in a single place.

Question:

You are working with an Azure SQL Database. When you display dates and times, you notice that they do not match your local time zone of CEST.

Can you change the server settings to Central European Standard Time (CEST)?

I commonly run into a few connection-related scenarios:

I’m working on a large query and need to run it against several servers, not concurrently, but one after the other.
I’ve just made a database connection, and got my query ready, only to discover that I’ve connected to the wrong server.

Either way, what I’ve seen people do in these scenarios is to:

Select all the text in the current query
Copy it
Open a new query window
Paste the code

That’s all good but SSMS has had a simpler way of doing this for quite a while.

There is a really common misconception about output order for T-SQL queries. I can’t tell you how often I’ve heard people say that if you don’t specify an ORDER BY clause, then you’ll see the rows returned in the order of the primary key.

The assumption they’re also making is that the primary key is the clustering key. And that’s not necessarily true either. You can have a non-clustered primary key on a table.

Everyone who’s worked with SQL Server for any length of time, has had the experience of executing a T-SQL script, and then noticing, with horror, that they’ve just executed the script against the wrong server.

You know the feeling. It even happens at Christmas time, just when you were hoping to get away from work for a few days, or when you are the unlucky one who’s doing on call work.

Section: Administration Level: Advanced

Question:

A storage failure occurs and during recovery, a data file from your database was lost.

Transaction log backups are taken every 5 minutes.

Periodically, when data is being loaded into the database, Bulk Logged mode is used. At the time of the failure, the database was still in bulk logged mode.

When I am writing my own code using a .NET (or other) language, I have a great deal of control of how the connection string that my application uses to connect to SQL Server is configured.

In particular, I might need to add another parameter or two.

As a simple example, I might be working with a multi-subnet Availability Group, spread across a production site and a disaster recovery site. It’s common to then have an Availability Group Listener in both subnets.

In previous posts, I’ve been talking about how to use snippets in SSMS and how to create your own. There are several types of snippets and one of the special types of snippets that I want to mention are the “surround with” snippets.

If you look at the following block of code:

Imagine that you want to execute the four highlighted lines only when a condition is true. If I hit Ctrl-K and Ctrl-S while they are highlighted, I’m prompted with this:
