Introduction Sometimes it doesn't matter whether your query is efficient or not. For example, you might write a query you expect to run only once, and it might be working on a small dataset. In this case, anyth
For better performance we need to use best faster and efficient queries. This paper covers how these SQL queries can be optimized for better performance. Query optimization subject is very wide but we will try to cover the most important points. In this paper I am not focusing on in- depth...
T-SQL is an extension to the ANSI SQL standard and adds improvements and capabilities, making T-SQL an efficient, robust, and secure language for data access and manipulation.Although many tools are available for designing your queries visually, such as the Visual Database Tools that are ...
My current company already has a way to access databases through Excel bypassing SQL altogether. However, I'm intrigued by the idea of directly writing SQL queries for data retrieval. I have decent SQL skills, but I'm looking to polish them further. Additionally, I'm interest...
