In database management systems, an aggregate function is a function that performs calculations on a group of values and returns a single value. It is used to summarize the data. It performs calculations on multiple rows of a single column of a table to form a single value of more significant meaning. These Aggregate functions are inbuilt SQL functions. They are often used with the GROUP BY clause to calculate an aggregate value for each group. Some of MySQL Aggregate functions are:
The AGGREGATE Functions ignore all NULL Values. AVGThe SQL AVG function calculates the average value of a column of numeric type. It returns the average of all non-NULL values. Syntax
For example:
COUNTThe COUNT function is used to count the number of rows in a database table. It can work on both numeric and non-numeric data types. The SQL COUNT function returns the number of rows in a table satisfying the criteria specified in the WHERE clause. It sets on the number of rows or non-NULL column values. COUNT function uses the COUNT(*) that returns the count of all the rows in a specified table. COUNT(*) considers duplicate and Null while Count(column_name) removes Null values records from counting.

MINThe aggregate function MIN() is used to find the minimum value or lowest value of a certain column or expression or a set of values. It is applicable to all the data types. It excludes NULL values and return distinct value as a result. Syntax
