SQL Bulk Insert Concurrency and Performance Considerations
January 18, 2019One 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.

Generating Schedules with SQL Server Agent
January 15, 2019Summary
SQL Server Agent allows us to create jobs and assign any number of schedules to them. This allows for great flexibility when deciding when jobs should run. Over time, as the number of jobs and schedules increase on a given SQL Server, it can become challenging to fully understand when and how often jobs run during a given span of time.

SQL Server Replication with a table with more than 246 columns
January 14, 2019Problem
In our environment we use SQL Server merge replication to replicate data to multiple subscribers. We had a situation where a table needs to be part of merge replication and the table has more than 246 columns. Merge replication supports tables with maximum of 246 columns. In this article let us see how to replicate a table with more than 246 columns.
Managing data with SQL Server FILESTREAM tables
January 14, 2019SQL Server FILESTREAM allows storing the Varbinary (Max) objects in the file system instead of placing them inside the database. In the previous article – FILESTREAM in SQL Server, we took an overview of the FILESTREAM feature in SQL Server and process to enable this feature in SQL Server Instance.

Working With Line Numbers and Errors Using Bulk Insert
January 10, 2019In the first part of reviewing the basics of bulk insert, we looked at importing entire files, specifying delimiters for rows and columns, and bypassing error messages. Sometimes we’ll want to skip first and ending lines, log errors and bad records for review after inserting data, and work with data types directly without first importing using a varchar and converting to the data type later. In this part, we look at these techniques using T-SQL’s native bulk insert.
SQL Server Audit Overview

Tracking Times In Data Flows for Finding Performance Issues
January 9, 2019We’re facing a challenge with several of our data flows that use more time than they have in the past and we’re not sure when this trend started. We know in the past month, our reports have been delayed by over a day from the start to the finish. For some of our data flows we use SQL Server Agent that calls SSIS packages or procedures, while some of them use a custom data import and reporting application we’ve created. How can we track the length of time for these data flows, since we’re using a combination of tools for importing data?
SQL Server Transaction Overview
January 8, 2019In general, a Transaction is a single unit of work consists of multiple related tasks that should succeed or fail as one atomic unit. To make the concept of the transaction more familiar and why it should go all or none, imagine one of the most critical transaction examples in our daily life, which is withdrawing money from the ATM.

T-SQL’s Native Bulk Insert Basics
January 8, 2019From troubleshooting many data flow applications designed by others, I’ve seen a common pattern of over complexity with many designs. Putting aside possible risks by introducing too much complexity, troubleshooting these designs often involves opening many different applications – from a notepad file, to SSIS, to SQL Server Management Studio, to a script tool, etc. It may sound like many of these are doing a hundred steps, yet many times, they’re simply importing data from a file, or calling five stored procedures and then a file task of moving a file. This complexity is often unnecessary, as is opening many different tools when we can use a few tools and solve issues faster.

Improvements of Scalar User-defined function performance in SQL Server 2019
January 4, 2019In SQL Server, we normally use user-defined functions to write SQL queries. A UDF accepts parameters and returns the result as an output. We can use these UDFs in programming code and it allows writing up queries fast. We can modify a UDF independently of any other programming code.
SQL Server Code simplification using synonyms
January 4, 2019Problem
In our environment, we use different DB servers and these servers are linked via Linked servers for cross server transactions. We use these linked servers in our stored procedures. The server names are different in different environments and we had to change the server names manually when we promote the stored procedures to other environments. There is a chance of errors while changing the server names manually. In this article let us see how can we eliminate changing the code manually.

Power BI Desktop Q&A data interaction examples
January 3, 2019The 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.

Uninstalling SQL Server on Ubuntu
December 31, 2018We learned to install SQL Server 2019 installation on Ubuntu without a Docker Container in one of my previous articles, but we might also get a request to uninstall SQL Server running on Ubuntu as well. Both the installation and the uninstallation of SQL Server is different in Linux than of Windows OS. In windows, we can remove or uninstall any program using the add or remove programs feature. In Ubuntu, We need to run the commands in order to uninstall the programs. However, before performing uninstallation, we need to take care of the below point.
