Aggregate Functions in Laravel Eloquent Model

Did you know that an aggregate function works on a set of values and returns a single value?

All aggregate functions disregard null values except the COUNT(*) function.

Additionally, we can use aggregate functions with the SELECT statement’s GROUP BY clause.

Aggregate functions like max, min, count, average, and total are included in Laravel.

After we create an Eloquent model and a database table associated with it, we can retrieve data from the database.

Consider each Eloquent model as a query builder that lets us query the database table linked with the model.

Additionally, we can use count,min,max,sum and avg aggregate functions by Laravel to get values instead of a full model instance. We can call any of these methods after constructing the query.

Did you know we can combine these aggregate functions with query constraints?

This helps filter the data before performing the aggregation.

Here is an example:

In this example, we’re using the `count` function to get the total number of pending tasks. `Max` to find the highest salary in the IT department, and `sum` to calculate the total sales amount for completed orders in the last month. These aggregate functions offer an easy way to get data based on certain criteria.
