I’ve had many developers ask me how can I turn off those annoying completion time messages in SSMS?.

A while back, the product team decided that we’d all like completion times shown in the Messages output tab. I don’t share their enthusiasm for them.

For a start, a completion time was already shown here in the Properties window for the query, along with much more info:

So, for me, it really was quite irrelevant. Worse, I often use the output of the Messages tab as text for scripts, etc. The last thing I wanted were a bunch of completion times sprinkled through those.

This is a post in the SQL Interview series. These aren’t trick or gotcha questions, they’re just questions designed to scope out a candidate’s knowledge around SQL Server and Azure SQL Database.

Section: Development Level: Intro

Question:

In the following WHERE clause, both AColumn and AnotherColumn are NULL.

WHERE AColumn = AnotherColumn

What is the effect of the WHERE clause?

Answer:

In SQL boolean logic, the expression NULL = NULL returns NULL and not True. So the WHERE clause would exclude the rows.

In SSMS, query results are normally shown at the bottom of the query window.

This can greatly reduce the screen real estate both for the query, and for viewing the results.

In Tools, Options, Query Results, SQL Server, Results to Grid, there is an option to Display results in a separate tab. This can be very useful and generally you will also want to choose the extra option to Switch to results tab after the query executes.

This is the first tale in a series of stories about data. I hope you enjoy the series.

I have a number of clients that I spend a day or two with each month. I like this style of engagement as I get to know the staff and their systems over a period of time, can see the improvements that we make over time. The staff members also know that if they have issues that aren’t desperate, they can save them up for the days that I am onsite. When I arrived at one of these customer sites recently, several of the staff members had grins on their faces, and one told me that Terry (well let’s call him Terry anyway) had really broken something.

Over the past few months, we’ve been updating and converting courses that we used to run in-person, to a full online and on-demand format. The latest course is on High Availability for SQL Server.

We’re pleased to announce that this course is now available. This is another course that we’ve had so many requests for. You can find details of it here:

SQL Server High Availability for Developers and DBAs

It’s time to keep your SQL Server running - no matter what !

In a previous post , I mentioned that when a long running query completes, I might not have been waiting around for it, and so I wanted to know when it completed.

But sometimes I do wait around for a query to complete, yet I’m distracted by other things and don’t realize that the query has actually completed. That’s not surprising because if a query takes a long time, I’m probably going to go on with other work while that’s running.

Section: Security Level: Medium

Question:

Is it possible that revoking a permission can cause a user to be able to access a resource, when they previously could not?

If so, how?

Answer:

REVOKE can remove either a GRANT or a DENY. Revoking a DENY can cause a user to be able to access a resource that they previously could not.

It’s likely that everyone who uses SSMS knows how to tell how long a query ran for. You can see it in the bottom right of the status bar when a query finishes.

But one question that often comes up with a long-running query is when did my query finish?

That’s not in the status bar and many people don’t seem to be aware that you can determine that.

It’s part of the data in the Properties window. So when you come to a query window where the query has finished, and you’re wondering when it finished, hit F4 (or right-click in the window and click Properties), and you’ll see this info shown:

This is probably one of the simplest tips that I’ve published, yet I’m endlessly surprised how many people do not realize that it’s available.

When you have a script loaded in SSMS, and you execute the script, you might run into an error like this:

To find where the error is, just double-click the error down in the Messages tab. I double-clicked it, and it took me directly to the error and highlighted it:
