How to automatically maintain Full-Text indexes and catalogs

September 21, 2017 by

Introduction

In a previous article entitled Hands on Full-Text Search in SQL Server, we had an overview on the Full-Text feature as it’s implemented in SQL Server. We saw how to create Full-Text indexes and that they were stored inside a container called a Full-Text catalog. We’ve also seen that, by design, this kind of index will generate a fragmentation.

How to replace hardcoded lookups using SQL Server Master Data Services

September 14, 2017 by

Introduction

A big part of the technical debt in my organization’s data warehouse (DW) and business intelligence (BI) environments relates to hardcoded lookup data. This is data required by the business to make sense of transactional data but was never planned for in the underlying source system and consequently get injected into DW and BI solutions. Inevitably, it is only a matter of time before DW and BI team lose track of the places wherein the hardcoded data reside thus making it difficult to maintain. Furthermore, due to lack of documentation or staff retention, anyone who subsequently takes over these DW/BI solutions can unknowingly create duplicate lookup data. In this article, I explain how we reduced such technical debt in my organization by moving most of the hardcoded lookups into SQL Server Master Data Services (MDS).

How to connect to (and query) Power BI and Azure using PowerShell

September 13, 2017 by

Power BI “as a whole” is a bit of a black box. If you’re like me and used to using SQL Server & its components; SSRS, SSAS etc. you have access to installation directories, Event logs, trace logs, error logs, chocolate logs? You can see full instances & their contents in one go, whether that be databases, reports or cubes. It gives you the control over & responsibility for performance & maintenance.

How to Capture Database(s) usage stats using sp_spaceused and PowerShell

September 11, 2017 by

Today’s businesses work with huge volumes of data. Sometimes, understanding the granularity of the data is helpful in data administration. Understanding the granularity poses unique challenges though and the database administrator needs to balance the key business and technical metrics of the environment. One of the key technical metrics is disk space estimation, which is vital to capacity planning and forecasting. The simplest way to get this information is by using the system stored procedure, called, sp_spaceused. The growth metrics can be captured periodically and stored in a central repository, a repository dedicated to helping with capacity planning and forecasting the disk requirements. This is a critical part of the day-to-day activities of a database administrator.

Synchronizing SQL Server Instance Objects in an Availability Group

September 8, 2017 by

Availability groups can no longer be considered new. The feature was released in SQL Server 2012 but I often notice that SQL Server Failover Cluster Instances (FCIs) are much better understood. For a very long time, when people thought about SQL Server they thought about the entire instance as a unit. Microsoft has been implementing new features and services which begin to segment the concept of an instance from the concept of a database.

Using Many-to-Many Relationships in SQL Server Analysis Services (SSAS) 2016

September 7, 2017 by

The Multidimensional Cube option of Analysis Services has handled many-to-many relationships with ease for many versions before 2016. The Tabular had a work around using DAX formulas until the release of SQL Server 2016. There are still some limitations to many-to many in Tabular but of course, there are some “tricks” to overcome the limitations. But, the many-to-many relationship will be in businesses data for many years to come. A solution has to be provided when it comes to Analysis Service databases.

How to drop a role in a SQL Server Database

September 6, 2017 by

Introduction

Let’s say we have a database role that we don’t need anymore because we defined another security policy using another database role. What are the steps to follow in order to properly drop this database role? That’s the question this article will try to answer, covering as many cases as possible.

In the following article, we will consider the simple steps we can follow in order to do this task using both SSMS and T-SQL. Then, we will focus on some facts that will lead us to the conclusion that, if we do it this way, it won’t work every time. We will list some situations where it could fail and define a test case situation in order to create a stored procedure that will do the job correctly, in all cases bymanaging these situations.

Nested Loop Joins in SQL Server – Batch Sort and Implicit Sort

September 1, 2017 by

In SQL Server, it`s not always required to fully understand the internal structure, especially for performance and optimization, if the database design is good, because SQL Server is a very powerful Relational Database and, as such, it has many inbuilt optimization processes which assure a response to the users as fast as possible. But it is always beneficial for the SQL Server developers and administrators to understand the internal structure of the SQL Server so that they can understand and fix the problems that slowed the response of the Database.

What is the difference between Clustered and Non-Clustered Indexes in SQL Server?

August 28, 2017 by

Indexes are used to speed-up query process in SQL Server, resulting in high performance. They are similar to textbook indexes. In textbooks, if you need to go to a particular chapter, you go to the index, find the page number of the chapter and go directly to that page. Without indexes, the process of finding your desired chapter would have been very slow.
