Why do we need SQL Server 2017

September 18, 2017 Leave a comment

SQL Server 2017 (Linux)

DIM (Data is Money) is the latest or at-least a new business model. Microsoft did a fantastic job in implementing SQL Server in Linux as a cross platform. This strategy has surprised Microsoft community and overturned the way we think about Microsoft database management products. In this story, I am going to talk about the SQL Server 2017 on Linux.


SQL Server 2017 runs on Windows, Linux, Docker containers. It has key features that attract many industry leaders for these features.

  • Cost
  • Security
  • Performance
  • Simplicity
  • Flexibility
  • Everything built in


First of all, I would think about product cost. Because, there are many technologies available as an open source. Linux is open source and free for commercial use. So, we can remove Operating system license cost from the investment. Linux can run on any hardware and we can have affordable hardware to setup a business. It reduces the infrastructure cost. Well, With these two cost reduction options, it would possible to achieve ROI in short period of time.

  • With SQL Server 2017 on Linux, it’s possible to realize a lower total cost of ownership (TCO) and quicker return on investment (ROI)
  • Expand your hardware options and achieve ROI more quickly with Linux.
  • Mobile BI anywhere at a fraction of cost.


Next, with the current digital environment, we are worried about data protection. Past several yearly we have been hearing about data breaches in different sectors. Some events are unavoidable but we need to take maximum effort to protect it. In this way, we need to give preferences to security. So, what kind of security does SQL Server have?

SQL Server 2017 – Data Sheet

  1. Fewest NIST vulnerabilities over last 7 years
  2. Encrypt data at rest and in motion with Always Encrypted
  3. Dynamic Data Masking conceals sensitive data
  4. Control access to database rows with Row-Level Security


We do not have much time to wait for a task to complete. It is due to heavy competition and vast amount of data to process to get serious decision quickly. Such as, Weather forecast, Medical diagnosis and real-time sale performance during holidays, etc. So, what does SQL Server 2017 have?

From Data Sheet:

  • Speed query performance without tuning using Adaptive Query Processing
  • Faster transactions with In-Memory OLTP and up to 100x faster analytics with in-memory Columnstore
  • Real-time operational analytics when you combine inmemory technologies


Who do like to spend lot of man hours for just migrating database from one platform to others. With SQL Server 2017, we can transfer database from Windows to Linux easily by taking backup and restore. For security, we can use encrypted backup with master key.



This word “Flexibility” is more complicated then it looks. Because, it has to satisfy every audience from every perspective. SQL Server 2017 is also a flexible platform to connect with any application. Also, it gives various flexibility for language of your choice, on the platform of your choice, on premises or in the cloud.

Language of your choice:

  • C#, Java, Ruby, or another coding language

Platform of your choice:

  • Support for Windows and Linux operating systems and Docker containers


  • Any cloud, any platform including OpenShift, Red Hat OpenStack, Kubernetes, Docker Swarm and Pivotal

Everything built-in:

SQL Server 2017 is a complete package that can be used for data management with 99.99% availability, simplicity, security, efficiency, affordability and reliability. Also, features like data compression, columnstore, partitioning, high availability, and disaster recovery.

I recent got to see the gartner’s magic quadrant for Operational Database Management Systems (ODMS). It is an interesting chart to visualize different companies and its market position in ODMS. There are 4 categories given in the chart with company’s position.

  • Niche Players –
    1. Couchbase
    2. MapR
    3. Clustrix
  • Visionaries
    • None
  • Challengers
    1. MarkLogic
    2. MongoDB
    3. EnterpriceDB
  • Leaders
    1. Microsoft
    2. Oracle

Insert or Update a File in Database – SQL Server

February 17, 2016 Leave a comment

Database is a repository for data of various formats. In the past, we use text files to store huge data and technology revolution has changed everything for what we store and How we store data. Big data is a good example. It happened in different forms as punch card, file system, relational database, graph db, NoSQL, NewSQL and etc.

But, in this blog post I am going to show a simple example for storing (insert) and altering (update) a binary image file stored in a table.


Create a Table

CREATE TABLE [dbo].[Images](

Sample Image file – SQL2016.jpg


Insert a record with a Image file

INSERT dbo.[Images]
(ImageDesc, ImageData)

Update an existing record with Image file

UPDATE dbo.[Images]
SET ImageDesc = ‘SQLServer’
,ImageData = BulkColumn from Openrowset( Bulk ‘C:\Test\SQLServer.jpg’, Single_Blob) as Img
WHERE ImageID = 1

This blog post is for code reference. You can use this code with not restriction.

How to debug T-SQL statement in SQL Server Management Studio

September 1, 2015 Leave a comment

Debugging is an important feature for every programming language with no exception SQL Server has this to help developer trace the their code and remove potential logical issue in the code before moving to production environment or simply to find the bug in the code.

SQL Server management Studio (SSMS) provide easy way to debug T-SQL statements.

Expectation: This blog post is to show how to use debug feature in SSMS with simple T-SQL statement.


declare @i as int, @n as int;
set @i = 0;
set @n = 5;

while @i < @n
set @i = @i + 1;
print @i;

Step 1: Open new query window and paste the above code

Step 2: Click Debug button on the toolbar


Step 3: Once debug starts, another debug related toolbar and windows (local variables, call stack) will show up. We can view and modify local variables and parameters, view global variables, as well as control and manage breakpoints while debugging.


Step 3: Click Step into (F11 – function key) to execute step by step.

This image is captured after 3 iterations. so, we can see the value of the variable @i = 3 and @n =5.


Try other debugging features in SSMS and keep  your code robust. Thanks.
