SQL Is Always Going to be Popular

Hiring staff is hard, and certainly it can sometimes be a challenge to find good people to build software and manage systems. Many of us want to be those good people, and we are looking to improve our own skills. I think that's one of the reasons that SQLServerCentral has become so popular. Many of us want to become better at our jobs.

It can be hard to determine what to learn and where to invest your time. I've talked with plenty of people that have worried about various Microsoft technologies and their longevity. Notification Services is the classic example, but I know people that have been wary of SSIS, Power BI, Azure, and more. It's daunting to consider spending 100 hours across the next year on some technology, only to find it's not likely to help you get the job you want.

Recently there was an analysis of the coding tests that were given to developers by various companies. This is interesting to look at from an employee view, when thinking what skills to work on. One thing I see is that SQL is constantly in demand. It ranks on the second most test language, only behind Javascript. That makes sense in that lots of companies need help with web technologies, and there are lots of these jobs.

What I'd also say is that most every job out there needs SQL. Whether you are a web developer, a mobile or client side developer, you use Java, Python, C#, or anything else, you'll work with a database. Even many of the NoSQL class of databases have added SQL as a query language for developers.

SQL, for all of its shortcomings, is a standard way of working with data. It's a skill that isn't likely to go away anytime soon and the more you can build efficient queries, the more likely it is that you'll impress someone in the next interview. Read our T-SQL articles and practice answering questions in the forums, and you might be surprised at how much of a T-SQL guru you can become.

Stairway to Exploring Database Metadata

SQL Server Extended Properties: Stairway to Exploring Database Metadata Level 7

Phil Factor from SQLServerCentral.com

In this level, I’ll introduce Extended Properties. As with the previous levels, I want to illustrate as much as possible with practical and immediately useful code.

Never Create Columns with ANSI_PADDING set to OFF

Site Owners from SQLServerCentral

There is no good reason for having ANSI_PADDING set to OFF when you create tables in SQL Server. It was provided purely for legacy databases that had code that assumed the old CHAR behavior for dealing with padding, and its use has now been deprecated.

In this tip we cover how to manage application secrets in a development environment to securely store database credentials.

Free eBook: SQL Server Execution Plans, Third Edition

Press Release from Redgate

If a query is performing poorly, and you can't understand why, then that query's execution plan will tell you not only what data set is coming back, but also what SQL Server did, and in what order, to get that data. It will reveal how the data was retrieved, and from which tables and indexes, what types of joins were used, at what point filtering, sorting and aggregation occurred, and a whole lot more. These details will often highlight the likely source of any problem.

  Question of the Day

Today's question (by Steve Jones - SSC Editor):

 

Filtering Data

I have a simple data frame that looks like this:
> passing.2019
     Player Yards Conf age
1   Winston  5109  NFC  26
2  Prescott  4902  NFC  25
3      Goff  4638  NFC  26
4    Rivers  4615  AFC  38
5      Ryan  4466  NFC  34
6    Wilson  4110  NFC  31
7     Brady  4057  AFC  42
8      carr  4054  AFC  28
9     Wentz  4039  NFC  27
10  Mahomes  4031  AFC  24
I want to reduce this down to those players in the AFC that are older than 30. Which of these functions will do this?

  Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Get a couple fruits

I have this code:

DECLARE @s VARCHAR(500) = 'apple,pear,banana,peach,orange,strawberry,blueberry,lime'

SELECT TOP 2 *
 FROM STRING_SPLIT(@s, ',') AS ss

What is returned from this?

Answer: could be any 2 of the fruits from the string

Explanation: As with many SELECT statements, the output from STRING_SPLIT() is not guaranteed to be in the same order as the source string. In practice, this almost always returns apple and pear, but you should not count on this. Ref: string_split() - https://docs.microsoft.com/en-us/sql/t-sql/functions/string-split-transact-sql?view=sql-server-ver15
