SSIS and PowerShell – Execute process task
April 11, 2016Introduction
SQL Server Integration Services (SSIS) and PowerShell (PS) together offer a plethora of opportunities, and some shortcuts when having to import, export, or at times moving data. I have come across packages that contain a Script Task with lines and lines of C# code that, done with PowerShell, could make maintaining that package much easier. Overall, the most common thing I see Script Task doing is accessing the file system or doing some manipulation on a file. One thing I hope that picks up speed in the BI world of SSIS is utilizing PowerShell for these type of actions. This is not to say one is better than the other as you should pick what is best in your eyes, but when I can do operations against the file system with a one-liner in PowerShell it is just easier to maintain that in the package. In this article I will go over how you can use the most common task utilized for executing PowerShell code in an SSIS package: Execute Process Task.

March 16, 2016In the world of SSIS development architecture, preference should be given to extracting data from flat files instead of non-Microsoft relational databases. This is because you often don’t have to worry about driver support and compatibility issues in your SSIS development/server machine that is often attributed to non-Microsoft database vendors. In fact, I’ve been in several situations whereby we cannot upgrade to another version of SSIS (i.e. BIDS to SSDT) due to the lack of external vendor driver compatibility issues in the newer versions of SSIS.

February 19, 2016Introduction
In the article, Multiple Options to Transposing Rows into Columns, I covered various options available in SQL Server to rotating a given row into columns. One of the options included the use of a PIVOT relational operator. The mandatory requirement of the operator is that you must supply the aggregate function with only a numeric data type. Such a mandatory requirement is usually not an issue as most aggregations and subsequent pivoting is performed against fields of numeric data type. However, sometimes the nature of business reporting requests may be such that you are required to cater for pivoting against non-numeric data types. In this article we take a look at how you can deal with such requirements by introducing a workaround to pivoting on non-numeric fields.

January 4, 2016Introduction
One of the primary functions of a Business Intelligence team is to enable business users with an understanding of data created and stored by business systems. Understanding the data should give business users an insight into how the business is performing. A typical understanding of data within an insurance industry could relate to measuring the number of claims received vs successfully processed claims. Such data could be stored in source system as per the layout in Table 1:

August 14, 2015Introduction
There are great Microsoft tools to access to SQL Server in Azure. However, as a Database Developers and Administrators we need to help the end user to access to the information using a familiar and intuitive interface.
Most of the end users have a good knowledge in MS Excel. That is why it is recommended to connect our SQL Azure database to Excel. That way, the end user will be able to easily create reports, charts and generate useful information.
In this chapter, we will show how to connect to SQL Azure using Microsoft Excel.

April 6, 2015Introduction
A few days back I was looking at ways to access raw data from within Microsoft Dynamics CRM in an effort to extract the raw data and to place it in our data warehouse. I started to explore utilizing OData and SSIS to pull the necessary data from the cloud to our local warehouse.
Whilst there are known authentication issues between Dynamics CRM and the Microsoft OData SSIS data source (and thus we could not utilize this access method), I thought it to be so very powerful, that I began looking for other constructive manners in which to utilize the OData Source.

March 18, 2015Introduction
Have you ever felt like pulling your hair out, trying to ascertain exactly which fields in your existing Reporting Services datasets are being utilized by your reports. This happened to me recently during a corporate conversion and cleanup exercise for a database migration to the cloud.
The “aha moment” came after having presented a paper at the PASS SQL Server Nordic Rally (March 2015), when one attendee came up to me and asked if I knew of a method to do this. As they say ‘necessity is the mother of invention’ and spiking my interest, I played around until I came up with the solution that we are going to chat about today. The end solution may be seen below

March 16, 2015Introduction
Oft times we are forced into situations where we must clearly think outside of the box. In today’s “get together”, we are going to discuss a challenge that I encountered during the last week of February of this year. The client had been charting weekly business calls placed by his sales reps. Our client had been tracking these results within an Excel spreadsheet (see the screen dump below) and he would be using this spreadsheet to report the sales reps progress going forward. My task was to source this data for the corporate reports in Reporting Services, from this spreadsheet and do so on a weekly basis. The client, being resistant to change, was not willing to change the format of the spreadsheet to something more conducive to be utilized by the chart that he wished to produce (see immediately below).

March 4, 2015Introduction
As you will remember from our last “get together” we created an application that permitted us to report upon financial data based upon an unorthodox financial year. In fact, our fiscal year started in July and ended in June. We created a chart to display the data.
In today’s “get together” we are going to push our application a bit further and build in a subreport which will bring up the underlying data when the end user clicks upon the chart for any particular month. Thus should the user click on February 2015, then all of February’s data (for the selected funds) is shown in a matrix. If the user chooses March, then March’s data is shown.

Using Master Data Services in SQL Server to quickly create a GUI that may be maintained by the end user
February 20, 2015Introduction
Oft times we are forced into situations where we clearly need to think outside of the box. A case at hand arose early in 2014 where one of our client’s required a “quick and dirty” front end to modify data within a table that reflected the outstanding balances (of their clients) and the attempts that they had made to recover these funds. Master Data Services seemed to be the way to go!

February 12, 2015Introduction
A few months back, I presented a paper at SQL Saturday 327 in Johannesburg, South Africa. Late last month I received an email from one of the attendees. His issue was quite interesting and I decided to share it with you. The gentleman wanted a SSIS script that would permit him to extract data from a SQL Server database table and place it in a CSV file with a dynamically allocated name. Being a strong advocate of using the SSIS toolbox, I experimented with an alternative solution. We are going to construct THIS SOLUTION in today’s get together.
Let’s get started.

SQL Server security mechanism – How to control what data are users able to view within their reports
January 8, 2015Introduction
A few years back, a client asked me to implement a quick and dirty “security mechanism” to control what data the myriad of users were able to view within their reports. There were numerous tables with multiple columns and all departments (within the enterprise) had their data within these tables.
SQLShack Industries has tasked us with creating a similar quick and dirty “security mechanism”. We shall attack this challenge by creating the necessary stored procedures (to extract the required data) and then utilize these stored procedures to render and consume the data within our reports.
