The Bit Bucket

I started working with SQL Server in 1992, but all through the 1980’s and 1990’s, I was also working with Progress 4GL. I thought it was the best of the character-based 4GLs but unfortunately, they did a poor job of migrating to Windows and we decided to stop using the product.

One thing that I used to love with Progress though is that the metadata for each column in the database was much richer than what is present in SQL Server. In fact, Microsoft Access was probably closer to it in that regard. It’s something I really missed when moving to SQL Server. In Progress, when I defined a column, I could also define things like:

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: Administrator Level: Medium

Question:

Your database application has been suffering from signficant blocking issues.

One developer has suggested enabling RCSI for the database.

If you do that, what’s different about how the database would operate?

What code changes are needed to use it?

One thing that has annoyed me for a long time is why applications and systems make it so hard to disconnect yourself from a tenant that you don’t control. Here are two examples:

Stripe Connect

The first one that’s frustrated me lately is Stripe. Setting up your own account is straightforward, and leaving isn’t too hard.

But they have a service called Stripe Connect. In this case, the account is basically set up for you by a vendor you are dealing with, essentially on your behalf.

Over the years, one area that I have a great interest in, and yet I think gets nowhere near the right amount of attention is API design. So I was really interested to hear fellow MVP Valerio De Sanctis’ ideas in the new book Building Web APIs With ASP.NET Core .

API Design and Standards

I can’t tell you how many times I’ve had to work with poorly designed APIs. It affects me when working with data, but also affects almost every aspect of computing.

I’ve mentioned in an earlier article about scripting multiple objects at once, how useful the Object Explorer Details window is, and how little understood it is.

Another useful option in it, is that the displayed columns can be changed. In particular, you can add columns that would be useful. Let’s look at an example.

In Object Explorer, I’ve expanded the WideWorldImporters database and clicked on the word Tables:

Next, I hit the F7 key, and the Object Explorer Details pane opens showing this:

Question:

You need to extract the hour component from a datetime value.

Which function should you use?

Answer:

To do this in SQL Server, you should use the DATEPART function.

If you want to script all the indexes on a table (or all the tables, all the stored procedures, etc, etc.), you can do that the long way by using the Generate Scripts right-click option for a database, but there’s a better way.

Let’s use the Purchasing.PurchaseOrderLines table from WideWorldImporters as an example. Here are the indexes on it:

The scripting options are well-known. You right-click the object, and can navigate to the scripting option:

Question:

You have a table named HumanResources.Employees. Some employees are managers.

You want to join the table to itself to join employee rows with their manager rows.

What is required when you join a table to itself, that is not required for joining separate tables?

Previously I showed how useful it is to be able to drag columns from either a table or from user-defined table type onto a query window.

But one of the first comments I hear from people who did that is:

I hate all those square brackets. How do I stop that?

The option to do that was added to Tools> Options > SQL Server Object Explorer > Commands:

Bonus points for the team because they also provided us with an option to decide whether schema names are dragged as well. That’s mostly used for tables but also applies to other schema-bound objects like stored procedures.
