SQL Bulk Insert Concurrency and Performance Considerations January 18, 2019 by Timothy Smith 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 »

Generating Schedules with SQL Server Agent January 15, 2019 by Ed Pollack Summary 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. Read more »
SQL Server Replication with a table with more than 246 columns January 14, 2019 by Ranga Babu Problem 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, 2019 by Rajendra Gupta SQL 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. Read more »

Working With Line Numbers and Errors Using Bulk Insert January 10, 2019 by Timothy Smith In 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 January 9, 2019 by Ahmad Yaseen To fill an optimal role in all business’s computerized operations, information technology systems and infrastructure should be guaranteed, well controlled, aligned with the business goals and secured.

Tracking Times In Data Flows for Finding Performance Issues January 9, 2019 by Timothy Smith We’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, 2019 by Ahmad Yaseen In 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, 2019 by Timothy Smith From 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. Read more »
Improvements of Scalar User-defined function performance in SQL Server 2019 January 4, 2019 by Rajendra Gupta In 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, 2019 by Ranga Babu Problem 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. Read more »
