Can you list the main aggregate functions used when working with SQL queries?

The main aggregate functions in SQL that are commonly used for data processing:

• COUNT() — counts the number of rows or values in a column.
• SUM() — calculates the sum of values in a column.
• AVG() — calculates the average value.
• MIN() — finds the minimum value.
• MAX() — finds the maximum value.

Example of usage:

SELECT COUNT(*), AVG(price), MIN(price), MAX(price) FROM products;
