Come back when you're done reading and we'll continue. Let's now go to the examples and see how RANGE works in practice! If you're new to SQL window functions, maybe you should check what window functions are and how they compare to aggregate functions first. Those are PostgreSQL, MySQL, and Oracle DB. Regarding the date/time data types, only a very few popular databases support using them with the RANGE clause. Unfortunately, Microsoft SQL Server does not support it. You can use the numeric data types and the RANGE clause in almost all popular databases. You can use two data types with the RANGE clause: numeric and date/time types. Which Data Types Can I Use in the RANGE clause? The RANGE clause, on the other hand, limits the rows logically it specifies the range of values in relation to the value of the current row. The ROW clause does it by specifying a fixed number of rows that precede or follow the current row. However, each clause does it differently. They do, however, have the same purpose: to specify the starting and ending points within the partition, with the goal of limiting rows. Are the RANGE and the ROW Clauses the Same? Ready to dive in? Great! First, let's talk about RANGE and ROW. Feel free to have your Window Functions Cheat Sheet open while reading this article. It's normal to forget this syntax, especially if it's new to you or you don't use it very often. But when you use the ORDER BY, the default window frame is RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW. The default window frame without the ORDER BY is the whole partition. When you look at the syntax above, you see that both ROW or RANGE can be part of the window function. When I'm talking about the RANGE clause, I'm talking about the one used in SQL window functions, which have the following syntax:
