How to execute a Deployed Package from the SSIS Catalog with various options

March 21, 2017 by

In my previous two articles on SQL Server integration Services (SSIS), Parameterizing Database Connection in SSIS and Deploying Packages to SSIS Catalog (SSISDB), packages were developed, deployed and configured in the SSIS Catalog. Now, it is time to execute the packages with various options. There are a couple of ways to do this, but we need to be able to change the parameter values as well as monitor for failures or successes.

Some uncommon but useful T-SQL and Database Engine Enhancements in SQL Server 2016

March 20, 2017 by

SQL Server 2016 is the most advanced version of Microsoft’s Data Platform released yet. This is obviously my favorite one as it has tremendous capabilities and enormous features. These new additions not only enhance the productivity of its users (Database Developer, DBA or Application Developer), but also enable the enterprise to use its data more effectively and efficiently.

The evolution of SQL Server Data Tools (SSDT) for Business Intelligence development

March 9, 2017 by

By all accounts, the introduction of SQL Server Data Tools (SSDT) in SQL Server 2012 was a watershed moment for many SQL Server developers. For better or for worse, SSDT as an IDE for business intelligence development changed – amongst other things – the way we deployed our SSIS packages (i.e. package vs project deployments), simplified Tabular Model development, and also introduced us to the SSISDB. Likewise the replacement of Business Intelligence Development Studio (BIDS) with SSDT had its detractors who were noticeably not very happy that in addition to installing SQL Server 2012 you still had to do a separate download and installation of BI templates for SSDT (previously, BI templates in BIDS were available as soon as you installed SQL Server 2005/2008). Although SSDT-BI is still being offered as a separate installation, subsequent releases of SSDT have included several enhancements changes that should go a long way to winning the hearts of its critics. In this article we conduct a comparative analysis of all versions (up until 16.5) of SSDT and identify all the major improvements that have been introduced in the BI templates.

How to work with filegroups in SQL Server and migrate data between them

March 8, 2017 by

As you may already have figured out, the default settings in SQL Server are not always the best. Such is the case when you are working with new user databases; usually you get a single data (*.mdf) and transaction log (*.ldf) file. The data file resides within the PRIMARY file group; the only one we have so far, and it will store all of our databases objects, system objects, user tables, user stored procedures and all other objects. In some cases this default configuration may be good enough for you, but let us cover why would you prefer a different configuration in your production environment.

How to import/export JSON data using SQL Server 2016

March 7, 2017 by

JSON is an abbreviation for JavaScript Object Notation. JSON is very popular and currently the most commonly used data exchange format. Most modern web and mobile services return information formatted as JSON text, all database web services, web browsers (Firefox, Internet Explorer) return results formatted as JSON text or accept data formatted as JSON. Since external systems format information as JSON text, JSON is also stored in SQL Server 2016 as text. You can use standard NVARCHAR columns to store JSON data in SQL Server 2016.

How to automate SSAS tabular model processing in SQL Server 2016

March 6, 2017 by

There are many ways to process your SSAS Tabular Model. This can be achieved in SSIS using the Analysis Services Execute DDL Task or manually, through Management studio GUI but to have a little fun & make the task more flexible I’m going to script this with ASSL/TMSL & build a notification round it. We can then schedule this as a step in a SQL agent job, call it from SSIS or PowerShell.

The impact of Residual Predicates in a SQL Server Index Seek operation

March 6, 2017 by


It is common assumption that an Index Seek operation in a query plan is optimal when returning a low number of output rows. In a scenario involving residual predicates, an Index Seek operation could be reading a lot more rows than it needs into the memory, then each row is evaluated and discarded in memory based on the residual predicate and returns low number of output rows.

This article will explain the concept and the impact of Residual Predicates in a SQL Server Index Seek operation.

How to reconnect to a SQL Server instance when all credentials have been lost

March 3, 2017 by

The Problem

I came across a strange and rare situation at a client recently, where they asked me to resolve a problem on Microsoft SQL Server but did not give me any credentials to connect to the system. I asked them to state the actual problem and the reply was “we lost all credentials”. A number of questions started to generate in my mind. How are applications running? The Answer was “The application login is embedded in a DLL and it’s a third party application which we don’t have support”. How can you lose all the SQL Server credentials? The AnswerIt was saved in a file and it was lost and the employee who knew it is no more working with the company”. Anyways, I had no choice but to have a solution for this strange problem.

Configuring the Azure SQL Database Firewall

February 28, 2017 by


The Azure SQL Database firewall lets you decide which IP addresses may or may not have access to either your Azure SQL Server or your Azure SQL database.

When creating an Azure SQL Database, the firewall needs to be configured before anyone will be able to access the database. By default, no external access to your SQL Database will be allowed until you explicitly assign permission by creating a firewall rule.

How to partition an SSAS Cube in Analysis Services Multidimensional

February 28, 2017 by

Partitioning is the concept where you divide your data from one logical unit into separate physical chunks. This can have several advantages, such as improved performance or easier maintenance. You can for example partition a table in a SQL Server database, but you can also partition your measure groups inside an Analysis Services (SSAS) Multidimensional cube. In this article, we’ll discuss how you can set-up partitioning. For more information about the expected benefits, take a look at Benefits of Partitioning your SSAS Multidimensional Cube.
