  Understanding SQL Functions SQL ( Structured Query Language ) functions are essential tools that simplify complex queries, improve code readability, and enhance database performance. These functions are predefined operations that take input values, perform specific tasks, and return output, often in the form of a single value or set of values. SQL functions are categorized into various types, including aggregate functions, scalar functions, string functions, date functions, and user-defined functions. 1. Aggregate Functions Aggregate functions perform calculations on multiple rows of data and return a single result. Common examples include: Snowflake Online Training Course SUM() : Calculates the total sum of a numeric column. AVG() : Returns the average value of a numeric column.
