Compute Cumulative Sum in SQL
In this article, we'll walk through a straightforward example of calculating a Running Total in Microsoft SQL Server 2019. This tutorial will make use of the SQL Server Management Studio (SSMS) and the powerful features of the SQL language.
The SQL query in this example is designed to calculate a Running Total, which is a common requirement in various data analysis scenarios. To achieve this, we'll be using a combination of the , , and clauses.
Let's dive into the example without specifying a particular database or table to be used. This allows us to demonstrate the concept in a more general context, making it easier for readers to adapt the technique to their own projects.
In this SQL Server example, the function is used to calculate the Running Total, while the clause with is employed to find the Running Total. The clause sorts the results, and the specification defines the range of rows to be included in the Running Total calculation.
It's worth noting that this SQL example demonstrates the use of the clause to find the Running Total in SQL Server. The clause allows us to perform analytical functions on sets of rows, making it an essential tool for calculating Running Totals and other aggregations.
The SQL Server Management Studio (SSMS) is used in this example, but the same principles can be applied in other SQL environments as well. This tutorial uses Microsoft SQL Server 2019 (version 15.x), with the RTM build number 15.0.2000.5 cited for reference.
By following this example, you'll have a solid foundation for calculating Running Totals in your SQL Server projects. Happy querying!
