Understanding Network Authentication Modes When configuring SSMS server properties, it is essential to understand the different authentication modes available.

Pandas Group by Number (Instead of Time) The pd.Grouper function in pandas allows for grouping data based on a specific interval, such as time. However, sometimes we need to group data by a different criteria, like a number. In this article, we’ll explore how to achieve this. Understanding Pandas GroupBy Before diving into the solution, let’s quickly review how pd.Grouper works. The Grouper function is used in conjunction with GroupBy, which groups data based on a specified column or index.

Setting Result Rows Dynamically in Dependency of Cell Content As data sources become increasingly complex, it’s essential to have flexible and adaptable query solutions.
