One common task in analyzing vehicle data is calculating the average fuel consumption. In this blog post, we will explore how to use the AVG function in SQL to calculate the average fuel consumption.

Understanding the Data

Before we dive into the SQL query, let’s understand the structure of the data we’re working with. Assume we have a table called fuel_consumption with the following columns:

• vehicle_id: the unique identifier for each vehicle.
• date: the date when the fuel consumption was recorded.
• fuel_consumed: the amount of fuel consumed in liters.

SQL Query

To calculate the average fuel consumption across all vehicles, we can use the AVG function in SQL. Here’s an example query:

SELECT AVG(fuel_consumed) AS avg_fuel_consumption
FROM fuel_consumption;

Let’s break down the query:

1. SELECT AVG(fuel_consumed) AS avg_fuel_consumption: This statement selects the average of the fuel_consumed column from the fuel_consumption table and aliases it as avg_fuel_consumption.

2. FROM fuel_consumption: This specifies the table from which we are retrieving the data.

Example Result

Assuming we have the following data in the fuel_consumption table:

Executing the SQL query mentioned earlier will give us the average fuel consumption:

avg_fuel_consumption
---------------------
48.75

Conclusion

Calculating average fuel consumption using SQL’s AVG function is straightforward and can provide valuable insights when analyzing vehicle data. By using simple SQL queries, we can efficiently analyze large datasets and gain important information about fuel efficiency.
