The Data Flow Task is an essential component in SQL Server Integration Services (SSIS) as it provides SSIS ETL developers with an ability to conveniently extract data from various data sources; perform basic, fuzzy to advance data transformations; and migrate data into all kinds of data repository systems. Yet, with all its popularity and convenience, there are instances whereby the Data Flow Task is simply not good enough and recently, I got to experience such inefficiencies. To demonstrate some of the limitations of SSIS’s Data Flow Task, I have put together a random list of Premier League’s leading goal scorers for the 2019-2020 season.Read more »

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.Read more »
Using Python SQL scripts is a powerful technical combination to help developers and database administrators to do data analytics activities. Python provides many useful modules to perform data computation and processing of data efficiently. We can run Python scripts starting from SQL Server 2017. We can create the ETL solutions to extract data from various sources and insert into SQL Server.Read more »
Power BI Desktop is a useful reporting and analytical tool to represent data in various formats. These presentations help us to quickly understand information and circulate it to stakeholders in a visual fashion.
In this article, we will show how to convert dates from dd/mm/yyyy to mm/dd/yyyy using the Script component and also derived columns in SSIS. We will also explain when to use a derived column (DC) and when to use the Script Component (SC).Read more »
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.
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.Read more »
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. See this article for what is possible with Power BI.
However, before we can execute complex SQL queries on CSV files, we need to convert CSV files to data tables.Read more »
This article will cover SQL bulk insert operations deterministic outcomes and responses covering not allowing any bad data to allowing all data to be inserted, regardless of errors.Read more »
This article will focus on the various ways to disable triggers in SQL Server so they won’t interfere with certain operations like bulk inserts.
One of the challenges we face when using SQL bulk insert from files flat can be concurrency and performance challenges, especially if the load involves a multi-step data flow, where we can’t execute a latter step until we finish with an early step. We also see these optimization challenges with constraints as well, as fewer steps to complete a data flow results in saved time, but possibly less accurate data.Read more »
In this article, we’ll discuss security implications of using SQL Bulk Insert and how to mitigate those risks.Read more »
In this article, we will explore the concept of using JSON data in SQL Server Reporting Services (SSRS). This usage concept will include a different approach than the usual methodologies because we will take advantage of SQL Server R service support.
What is JSON?
