Question
Write a query to display the number of electricity_reading in which the total_units per day is greater than 500. Give an alias name as 'count_total_units_500'.Note:1.

Specify condition on total_units column of electricity_reading table.3. Compare your executed result with the sample output given below.Sample output:
Solution
The query you're looking for would look something like this:
SELECT COUNT(*) AS count_total_units_500
FROM electricity_reading
WHERE total_units > 500;
This query works as follows:
SELECT COUNT(*) AS count_total_units_500: This part of the query is selecting the count of rows and giving it an alias name 'count_total_units_500'.FROM electricity_reading: This part of the query specifies the table we are selecting from, which is 'electricity_reading'.WHERE total_units > 500: This is the condition that the rows must meet to be included in the count. Only rows where 'total_units' is greater than 500 will be counted.
Please replace 'total_units' and 'electricity_reading' with your actual column name and table name if they are different.
