Question
QueryQ1Write a query to display the average 8th hour unit consumption from electricity reading. Give an alias name to the average 8th hour consumption as 'average_8th_hour_consumption'.
Solution
Assuming that you are using SQL and you have a table named 'electricity_reading' with a column named '8th_hour_consumption', here is how you can write the query:
SELECT AVG(8th_hour_consumption) AS average_8th_hour_consumption
FROM electricity_reading;
Here is the step by step explanation:
-
SELECT: This keyword is used to select data from a database. -
AVG(8th_hour_consumption): The AVG() function returns the average value of a numeric column. Here, it is used to calculate the average of the '8th_hour_consumption' column. -
AS average_8th_hour_consumption: The AS keyword is used to rename a column or table with an alias. Here, it is used to give the alias name 'average_8th_hour_consumption' to the average value of the '8th_hour_consumption' column. -
FROM electricity_reading: The FROM keyword is used to specify the table from which to select the data. Here, the data is selected from the 'electricity_reading' table.
