Understanding Date Ranges in Microsoft SQL Server Introduction Microsoft SQL Server provides various features for working with dates and date ranges. One of the most commonly used functions is the BETWEEN operator, which allows you to select data from a specific date range. However, when dealing with dynamic or user-inputted date ranges, things can become more complex. In this article, we’ll explore how to create a stored procedure in Microsoft SQL Server that accepts a date range from a user and returns the corresponding data.

Understanding the Problem and Solution When working with Pandas dataframes, it’s not uncommon to encounter scenarios where you need to calculate the number of weeks based on a specific date range.
