Welcome to our blog post where we will be discussing various concepts and ideas related to SQL Server. SQL Server is a powerful relational database management system that is widely used in the industry. Whether you are a beginner or an experienced developer, there is always something new to learn in the world of SQL Server.

QUOTED_IDENTIFIER and ANSI_NULL

When creating or altering SQL objects like Stored Procedures or User Defined Functions, you may have come across the terms QUOTED_IDENTIFIER and ANSI_NULL. In our blog post, we explain the significance of these settings and how they affect the behavior of your SQL code.

Working with Cursors

Cursors are a powerful tool in SQL Server that allow you to iterate over a result set and perform operations on each row. We provide a simple example of how to use cursors in SQL Server and discuss their benefits and drawbacks.

Finding the Nth Highest Record

While it is easy to find the top or bottom records in a database table, finding the Nth highest record can be a bit more challenging. In our blog post, we explore different approaches to finding the Nth highest record in SQL Server.

Performance Comparison – INSERT TOP (N) INTO Table

Did you know that you can use the TOP clause with the INSERT statement in SQL Server? In this blog post, we compare the performance of using TOP (N) with INSERT versus using INSERT with SELECT N. Discover the pros and cons of each approach.

Rollback TRUNCATE Command in Transaction

Contrary to popular belief, the TRUNCATE command in SQL Server is a logged operation and can be rolled back. We explain the details of how this works and provide a demonstration in our blog post.

Order of Columns in Update Statement

Have you ever wondered if the order of columns in an UPDATE statement matters? In our blog post, we delve into the topic and explain how the order of columns can impact the behavior of your update statements.

Improving Performance with Covered Indexes

Indexes play a crucial role in optimizing the performance of SQL Server queries. However, having too many indexes, especially covering indexes, can negatively impact performance. We demonstrate the concept of a covered index and how it can help reduce IO and improve query performance.

Concurrency Problems and Isolation Levels

Concurrency is a critical aspect of database systems, and SQL Server provides various isolation levels to handle concurrent transactions. We discuss the different types of concurrency problems that can arise and how SQL Locks can help mitigate them.

Running Multiple Batch Files in Parallel

Running SQL code in parallel can be a useful technique for improving performance. In our blog post, we explore how to run multiple batch files in parallel and discuss different approaches to achieve this.

Difference between COUNT(DISTINCT) vs COUNT(ALL)

The COUNT function in SQL Server has two options: COUNT(DISTINCT) and COUNT(ALL). In our blog post, we clarify the difference between these options and explain when to use each one.

Stay Connected and Social Media

Social media can be a valuable tool for staying connected and sharing knowledge. In our blog post, we share best practices for using social media effectively and discuss how it can benefit SQL Server professionals.

Various Leap Year Logics

Identifying leap years can be a fun challenge in SQL Server. In our blog post, we explore different ways to determine if a year is a leap year or not and discuss the logic behind each approach.

T-SQL Errors and Reactions

Encountering errors is a common part of working with SQL Server. In our blog post, we delve into how SQL Server reacts to errors and discuss the different types of T-SQL errors and their behavior.

We hope you find these SQL Server concepts and ideas helpful in your journey as a SQL Server professional. Stay tuned for more informative blog posts in the future!
