A festive gift: Working with images

November 2, 2016 by

Introduction

With Christmas just around the corner, in today’s “get together” I thought that we would have some fun by cataloging a collection of ‘your favorite items’. Whether it be a coin collection, a china plate collection or a stamp collection, the process is the same and certainly something that you will enjoy creating and maintaining. For today’s example, we are going to construct a “Postage Stamp” cataloguing system. We are going to see how we are able to get from this..

How to create and manage T-SQL code snippets

October 28, 2016 by

Introduction

Transact-SQL (T-SQL) snippets were first introduced in SQL Server 2012 Management Studio. T-SQL snippets are templates containing one or more T-SQL statements which you can easily use them when you develop T-SQL scripts. The main concept behind code snippets is code reuse. With code reuse you develop faster, easier and with less syntax errors. If you frequently use specific T-SQL statements, then you should consider creating snippets with these statements as they will help you a lot.

How to create and configure the Tree Map Chart in SQL Server 2016 Reporting Services

October 28, 2016 by

In the previous article, in this series, How to create and configure a Sunburst chart in SQL Server 2016 Reporting Services, we have explored new chart types in SQL Server 2016; the Sunburst chart and the Tree Map chart, that are used to display hierarchical data. The Sunburst chart is a way of presenting relational datasets together in a compact form. The Tree Map Chart is also a way of showing hierarchical data.

In this article, we are going to show how to create a Tree Map chart and its comparison with the Sunburst chart.

SQL Server 2016 Database Scoped Configuration

October 21, 2016 by

SQL Server 2016 introduces a new set of configurations that can be applied at the database level to control its performance and behavior. These configurations were previously applicable only at the SQL instance level before version SQL Server 2016, With the ability to configure settings at the database level, many databases that are hosted in the same instance can now be isolated from each other, with each database has its own customized configurations. The database level configurations allow us also to set different database configurations for the Always On Availability Groups primary and secondary databases to meet the different types of workloads.

Reporting from OLAP cubes made easy

October 19, 2016 by

Introduction

Last month I ran two Business Intelligence pre-conferences in South Africa. A interesting request arose during the course of the preconference in Cape Town. The individual wanted an approach to extracting data from an OLAP cube that would avoid intensive utilization of MDX and more reliance upon T-SQL. His main concern was with filtering the data at run time, via the report front end.

In this “fire side chat” we shall do just that, utilizing the cube that comes with the new Microsoft database “WideWorldImporters” and we shall learn how we can get from this

SQL Server 2016 Parameter Sniffing

October 19, 2016 by

SQL Server tries always to generate the most optimized execution plan for each stored procedure the first time that the stored procedure is executed. The SQL Server Engine looks at the stored procedure passed parameter values when compiling the stored procedure, the first execution, in order to create the optimal plan including the parameters and keep that plan for future use in the plan cache. This parameter analysis process is called the Parameter Sniffing.

Using Dynamic Data Masking in SQL Server 2016 to protect sensitive data

October 17, 2016 by

Dynamic Data Masking is a new security feature introduced in SQL Server 2016 that limits the access of unauthorized users to sensitive data at the database layer.

As an example of the need for such a feature is allowing the applications developers to access production data for troubleshooting purposes and preventing them from accessing the sensitive data at the same time, without affecting their troubleshooting process. Another example is the call center employee who will access the customer’s information to help him in his request, but the critical financial data, such as the bank account number or the credit card full number, will be masked to that person.

SQL Server Management Studio 2016 Productivity Enhancements

October 11, 2016 by

Problem Statement

Developers who work in both SQL and .NET world must have experienced the differences between Visual Studio IDE and SQL Server Management Studio IDE.

Being a full-stack developer myself, I always felt that SSMS lacked a lot of basic features when compared to the functionalities which Visual Studio IDE provided out of the box. With SSMS being tightly coupled with SQL Server Core engine, the IDE had quite a technical debt associated with it over a period of time.

My journey to PASS Summit 2016 via SQLShack

October 3, 2016 by

My name is Ahmad Yaseen and I am a senior SQL Server database administrator at Aramex International Company for more than six years, where I started building my experience in the SQL Server administration field. Being a SQL Server Database administrator in such big company is not that easy, as the difficulties that you may face is not only at the beginning. What makes the DBA job special is that it is a very deep job, in which you will learn new things, have to solve new problems, fall in strange situations and be under pressure every day, but it is an interesting job for me.

Introduction

As we are nearing the end of the North American summer, I thought that we would take a lighter look at nifty ways of reporting information. In today’s “fireside chat” we have a look at a unique way of displaying our information using charts and line graphs all in one single chart (see below). We shall take things one step further and work with the colour fill of the vertical bars to reflect the values that they represent.

How to filter and block the data access using SQL Server 2016 Row-Level Security

September 28, 2016 by

SQL Server 2016 came with many new features and enhancements for existing ones, that concentrate on the aspect of SQL Server security. One of the new security features introduced in SQL Server 2016 is Row-Level Security. This feature allows us to control access deeply into the rows level in the database table, based on the user executing the query. This is done within the database layer, in complete transparency to the application process, without the need to manage it with complex coding at the application layer.

How to filter multidimensional OLAP cubes in SSRS reports

September 28, 2016 by

Ever since the early days of my career, SQL Server Reporting Services (SSRS) has been one of my preferred data visualisation tools simply because end users and developers alike use it for free. Although a majority of my SSRS solutions have been based off a relational dataset that uses Transact SQL (T-SQL), I have also produced several reports that used Multidimensional Expressions (MDX) to connect and retrieve data from SQL Server Analysis Services (SSAS) multidimensional OLAP cube. Recently, I found myself having to refactor some of these SSAS based SSRS reports, particularly converting a single value SSAS-populated parameter into a multi-value parameter. In this article, I explore how you can go about making these changes using SSRS query designer’s design and query modes.

How to migrate an on premise SQL Server database to Azure

September 27, 2016 by

Lately database administrators often hear the question “have you tried Azure?“ or “can we use Azure for some of our databases?“. For me it was hard to answer these questions at first, but after a while I got to know what is really important behind these situations. In fact, what really matters is assessing the current environment, calculating the most suitable pricing tier and preparing a smooth migration.
