When developers are creating SQL Server stored procedures in T-SQL, I often see them embedding the name of the procedure as a hard-coded string within the procedure itself. Here’s a rough example:
The problem here is that if the procedure gets renamed, you then need to go and find every reference to it throughout the code.
The solution is to get the procedure name programmatically and use that:

We’ve been using SQL Server database projects ever since they were called “Visual Studio Team Edition for Database Professionals”. That was back in 2005 and the name was quite a mouthful.
Until the last year or so though, we’ve only seen fairly patchy adoption of them among our customers. Over the last year or so, this has really changed. We’re seeing so many customers starting to use them. Why?
I’m guessing that it’s the increased interest in using DevOps.

SQL Server Management Studio (SSMS) is based on the Visual Studio shell. What is puzzling sometimes is that features that are present in Visual Studio are not present in SSMS. One of these relates to themes. “Out of the box”, Visual Studio looks like this:
When you write code, the windows look like this:
Some people don’t like the “whiteness” of the whole screen and find darker colors easier to work with for long periods. In Visual Studio, you can change this. In Tools, then Options, you can change the theme:

One of the things that I’ve always thought was missing in SQL Server and the T-SQL language was a built-in view that showed reserved words, and even better, future reserved words.
It’s one thing to say that you can create a policy to avoid people using reserved words for table, column, or object names, but how exactly do you know that the name you’ve chosen is one of those?
We decided to tackle that with one of our free SDU Tools for database developers and DBAs.

The industry is clearly trending quite quickly towards Software as a Service (SaaS) applications. Rather than building monolithic chunks of code, new applications are often constructed by combining a variety of platform services, themselves usually delivered as Platform as a Service (PaaS) offerings.
Any application layers that you build above these services though, are only as good as the underlying services. And that’s where things can go very, very wrong quite quickly.

I was asked about this error message by a client just last week. They had what they thought was straightforward code, and yet were getting the error above.
What they were trying to achieve was to calculate the time as 10 minutes past midnight on the same day. So, they’d used SYSDATETIME() to get the current time (it could have been GETDATE() but SYSDATETIME() is the current version that returns a datetime2 data type).

In a post the other day, I described how to test if machine learning with R and/or Python was set up correctly within SQL Server 2017.
One of the comments on that post, said that the info was useful but they were still to be convinced why you’d want to have machine learning in the database in the first place.
Fair question.
I see several reasons for this. SQL Server Machine Learning Services is the result of embedding a predictive analytics and data science engine within SQL Server. Consider what happens in most data science groups today, where this type of approach isn’t used.

When working with SQL Server Management Studio, sometimes you need to show someone else what you’re working on, and the fonts that you’re using are just too small for someone looking over your shoulder or looking at a screen that you’ve shared with them.
What I often see someone do then, is to go into Tools and Options and start to change the font and color settings. The pain with this is that you then need to set them back later.

When you are trying to debug code in SQL Server T-SQL, or trying to monitor where code is up to, it’s common to add PRINT statements into the code.
These are fine when they are ad-hoc statements, but if you include PRINT statements in stored procedure code, and the procedure runs for any length of time, you’ll know that you normally don’t get to see the PRINT output in the Messages tab until the procedure ends.

Just a short note to let you know that I’m heading up to speak at SQL Saturday in Brisbane.
I’ll be delivering a session on SQL Server Management Studio tips and tricks and hope to get a chance to show you a number of ways to use SSMS that you might not have seen.
I really hope to see many of you there. If you are coming, please come and say hi.
