Importing compressed data into SQL Server: Add an OLE DB destination

Importing Data into SQL Server from Compressed Files

March 5, 2019 by

Introduction

I have seen many organizations receive data from various sources and import into SQL Server. You might receive data in various formats and want to import into SQL Server. We can prepare a ETL (Extract-Transform-Load) process to import data into the SQL Server. In doing so, might receive data in a compressed file, which helps to send data over the network using a ZIP file format because it reduces the file size significantly. If we are receiving a ZIP file to import into SQL Server, we need to unzip it and then only we can import data. We might need to create a ZIP file as well from the existing files.

SSRS Report Builder introduction and tutorial

March 1, 2019 by

The SSRS report builder is a powerful tool for data visualization. In this article, we will take a first step into familiarizing ourselves with the SSRS report builder and we will also demonstrate a very basic SSRS report example. Additionally, we will review the self-service business intelligence approach just because this approach can be implemented through the SSRS report builder very easily.

Power BI Desktop Pie Chart Tree

February 27, 2019 by

Power BI Desktop amplifies the value of data. We can connect to multiple data sources and visualize the data interactively. One of the best parts of Power BI Desktop is the custom visual feature. It allows developers to create custom visuals and users can then download these visuals from the marketplace and use it as per the data set requirements. We can prepare reports using Power BI Desktop and share the reports using the Power BI service.

Export SQL Server FILESTREAM Objects with PowerShell and SSIS

February 14, 2019 by

In this series of articles on SQL Server FILESTREAM (see TOC at bottom), we explored various ways to store unstructured data in the file system with the metadata in SQL Server tables. If we have a large number of objects in the file system, it is advisable to use the fast disk for storage purpose. It is faster and provides better IO in comparison with the traditional file system.

Power BI Desktop and Python; like Peanut Butter and Chocolate

February 13, 2019 by

Power BI Desktop helps to visualize complex data with the help of inbuilt and custom visualizations. It allows integrating data from the various data sources and preparing visualization from it.

Microsoft recently integrated the Python programming language in the Power BI. Python is a powerful object-oriented language and is used by the data analyst and scientist to analyze complex datasets. We can now use the Python as a preview feature in the Power BI August 2018 release onwards. We can now use Python scripts to generate custom visualization. The combination of these technologies is akin to 1 + 1 = 3 or like the famous ad for Reese’s Peanut butter cups, when chocolate was introduced to Peanut Butter 😉

Importing SQL Server FILESTREAM data with SSIS packages

February 1, 2019 by

Initial configuration

We have been exploring the SQL Server FILESTREAM feature in this ongoing series of articles. In this previous article, Managing data with SQL Server FILESTREAM tables, we wrote about inserting FILESTREAM data into a FILESTREAM table and performing DML activities on it. Suppose we have created the FILESTREAM database in our instance and now we want to insert a large number of files into a FILESTREAM container. It is easy to write out the insert queries for a small number of files, but if the numbers of files were in huge quantity, it would be difficult to write out the code and insert data into it. It is difficult to manage such kind of requests regularly in the environment.

Importing and Working with CSV Files in SQL Server

January 28, 2019 by

Introduction

CSV (comma separated values) is one of the most popular formats for datasets used in machine learning and data science. MS Excel can be used for basic manipulation of data in CSV format. We often need to execute complex SQL queries on CSV files, which is not possible with MS Excel. However, before we can execute complex SQL queries on CSV files, we need to convert CSV files to data tables.

Power BI Desktop Q&A data interaction examples

January 3, 2019 by

The Q&A feature in Power BI desktop provides a way to move towards Artificial Intelligence. In my previous article, we learned about the prominent Q&A in Power BI Desktop feature. We can get the desired result from Power BI Desktop by asking a question in Natural language. It converts the result set in tabular, chart format based on the requirement. It also helps users to build the question with its intelligence. It is one of the most incredible features of Power BI.

An MDS Driven Approach to a Turnaround Time Calculation in SQL Server

November 30, 2018 by

One calculation that you are almost guaranteed to have to produce in your career as a T-SQL developer relates to the calculation of a turnaround time. This is often a key KPI for measuring the performance of both individuals and teams, particularly when the business operates within a service-oriented sector i.e. customer support, transportation, healthcare etc. Turnaround time calculation does not only refer to business metrics rather any activity (i.e. ordering a pizza) with a recorded start and an end time can have its own turnaround time calculated. In this article we evaluate different options for calculating a turnaround time including using DATEDIFF function, creating your own user-defined function (UDF) as well as an integration with SQL Server Master Data Services.

How to create an email alert in SQL Server Agent for job failures

November 28, 2018 by

SQL Server Agent is a Microsoft Windows service which helps to execute, schedule and automatize T-SQL queries, Integration Service Package, SQL Server Analysis Service queries, executable programs, operating system, and PowerShell commands. These actions which are performed by SQL Server can be called by the SQL Server Agent. Maybe, we can liken SQL Server Agent to an alarm clock because the agent will execute the scheduled task when the time comes

How to Programmatically Pass Credentials in an Embedded Power BI Report

November 20, 2018 by

In the article, How to embed a Power BI Report Server report into an ASP.Net web application, we looked at available options for embedding a Power BI Report Server report into an ASP.NET web application. Since the publication of the article, I have received several questions relating to how one goes about programmatically passing credentials for report server connection within an embedded Power BI Report Server report. The simple answer to such questions is that it is currently not possible to implement user impersonation in an embedded Power BI Report Server. However, like in most scenarios, there are workarounds that one could temporarily employ – at least until Microsoft comes up with a permanent solution to what is becoming a top requested feature at ideas.powerbi.com.

Executive Summary

CDS for Apps VS Power Query – is there a difference? If so, what is that difference? Are they mutually exclusive or complement each other? Later I briefly outline Common Data Services for Analytics no, Power BI Datapools no again, actually Power BI Data Flows. It is difficult to keep up with the correct naming.

How to secure Reporting Services with Group Managed Service Accounts

November 7, 2018 by

With Reporting Services’ (SSRS) ability to scale out to multiple hosts, you may quickly come across the need to reuse domain accounts. Updating passwords for such accounts becomes a lengthy and risky process often requiring downtime. You may have a reliable process, set in stone for updating service account credentials every 30, 60 or 90 days or you could be stumbling across accounts that haven’t changed in 5 years and the passwords are in a shared text file somewhere. In either case, there’s risk that’s hard to mitigate without magically creating more hours in the day.
