Understanding SQL Server’s Conditional Aggregation SQL Server’s conditional aggregation allows us to perform complex calculations based on multiple conditions. In this response, we’ll explore how to use conditional aggregation to create a query that lists the quantity of products in six clusters: Q1 (<15), Q2 (15-20), Q3 (21-25), Q4 (26-30), Q5 (31-35), and Q6 (>35). Background To understand this concept, let’s first consider the basic syntax of SQL Server’s conditional aggregation.
