All aggregate functions are deterministic, which means they always return the same value when they run on the same input values. For more information, see Deterministic and Nondeterministic Functions. Analytic functions Analytic functions compute an aggregate value based on a group of rows. However,...
Scalar UDFs User-defined aggregate functions (UDAFs) Hiện thêm 2 User-defined functions (UDFs) allow you to reuse and share code that extends built-in functionality on Azure Databricks. Use UDFs to perform specific tasks, such as complex calculations, transformations, or custom data manipulati...

return results. These functions can be used in SQL queries to perform various tasks such as mathematical calculations, string manipulations, date and time operations, and more. SQL functions can be categorized into different types, including aggregate functions, scalar functions, and window functions....
